No # for me either yet. Was the last shipment all the remaining ones going out, or do you have another batch to ship? Not rushing your generosity of efforts; just curious.

Glad you popped in. I see that you have used different emails which confused things a bit.

Stand by for your tracking number!

So I practiced for a while on some 3/16 and it did good. After about 10 minutes it wouldn't maintain an arch. Today I went back out to cut some 1/2" and it cut ok for 10 seconds or so then went out. After it finishes the air purge I hit the trigger again and it goes for a second and shuts stops again. Air will flow, but no arch. Tried several settings, no change. Any ideas?

Sorry about any confusion. Thanks for the update.

Plasma cutters have a duty cycle Disney I think you definitely exceeded the expected run time . I do not believe you damaged unit but I suspect you may have used up one of the consumables in the torch head. I would recommend you open up the torch and check your consumables,suspect the electrode or the starter cartridge (if unit has one ) . All so check to make sure your air supply is providing dry air as this will negatively effect consumable life.

Make sure your ground is on CLEAN steel. Hit it with the grinder first if you need to. Also make sure the torch is not on top of a ton of rust and scale.

I second this, I finally had mine out last night after repairing the torch and had the same issue - replaced the consumables (which did not appear degraded) and it started working again.

On another note, I used it for about a half of an hour.... then it didn't turn off with the off switch and I had to unplug it. Has anyone else had this issue???? Or does anyone have any ideas???

Mine runs for a minute or so after I turn off the power. I'm guessing it will run till it's cool enough to safely shut down.

Back from vacation and ready to accept delivery of our cutter.

Hurrah!

Got tracking and it should be here by Tuesday!

Now I got to get air and electric hooked up!

Scary good!

Sean..........I don't know what to say, that would adequately thank you for what you have done for us all.

You should have a pile of karma, bigger than the stack of cutters.

It runs so it will properly cool down.

Given that a number of people seem to be new to plasma cutters I sure hope everyone is using the proper shaded eye protection. I see a lot of people who think that a plasma can be run with regular safety glasses or nothing and don't realize that plasmas produce UV just like welding does you are just not in as direct a line of path of the arc as when welding.

I've been using my welding helmet set on the grind setting.

Sean thanks got it and got to wire it and fire it up , ordered a leather wrap and will let every one know what I think of it. Here is a photo of the plug end and model # I use on all my 220 volt welding equipment. I all so replaced the grounding clamp with the harbor freight 400 amp clamp , I have been using these for the last 10 years or so on my welding equipment and have been pretty happy with it.

[Ohmthis]

Aqua moose, I'm back from vacation. Ohmthis #23 on the list and I believe #13 invoice.

 

[SlowAl]

Caught this as I was looking through the machine. This small circuit board at the front end was missing a standoff screw (you can see the hole for it right next to the standoff) so it was just sort of flopping around. I didn't check the screw and thread size but i had the same type of screw in my container of extra computer/hard drive/motherboard stand off installation screws.

If it wasn't mentioned already in the thread, make sure to double check all the screws you can see. About half of them were barely tightened finger tight.

 

[MoparTrucks]

I got mine today and it was everything advertised. Glad I participated in this lark and I am looking forward to putting it to work on numerous projects,

Thanks again AquaMoose....if there is a GJ hall of fame you rightfully belong there.

 

[Ameshel]

Hi everyone if any one needs to sell there unit let me know as a buddy is looking for one just private message me and will work out the details , thanks AndyM

[mindedc]

I don't mean to be a jerk, but please funnel all for sale units back through Aquamoose for those that paid for units but got short changed. After all the people that were on the original list have been at least offered the chance to get the unit they paid for in good faith, then we can expand to friends and family.

 

[bczygan]

Sean.......THANK YOU!

Got mine today!

 

[Will S.]

Seems awfully quiet around here, given that a whole bunch of new plasma cutters should be doing some cuttin. Is anyone using their's yet? How about posting up your thoughts on the new shop tool, and maybe some pics of what you're doing with it?

 

[Goohead]

Would like some feedback as well

Got mine but life got in the way

 

[AnEv942]

I played with mine a bit-mostly practicing cuts on different material. I did cut out some disks to be used as articulating feet for the cut table I built.


Other than just running some cuts on different material practicing, its a tool back on the shelf waiting for a need/project to use. Sorta anti climatic after waiting so long.

Cut out another silhouette just for grins, kinda fun but impractical.

Other than learning to use. Thin material just cant move fast enough trying to follow a pattern-bottom where I just zipped across zero dross, edge was round and smooth- interesting. Means just cutting raw materials speed has as much to do as air&amps.

But the machine itself- I had added a 20' cord which proved too short.


Re wired adding flanged male twist lock receptacle and made a 35' cord. Hardwired the 20' cord on mig replacing its 6' cord. (That was like a breadth of fresh air-opening up and working on the inside of the Lincoln).

Because I keep inadvertently firing off torch trigger I added a disable switch so I can 'park' torch and leave machine on/fan running for longer cool time My first impulse was to shut machine off. Need to come up with a positive torch holder?

Required moving internal board to get enough room to mount switch. Got second one threaded, as I was pulling out tap elbow hit drill press i jerked-snap. Used 3" 6-32 screws and replaced the stacked stand offs SlowAl showed.
. Wiped of the meaningless symbols
What else..

Oh, went to auto parts to get a longer strap for the work clamp...would have though I was asking for a ride to Pluto-had no clue what I wanted, bizzare. Cars dont use ground straps anymore?. Went to rv and hardware. Guy at hardware knew what it was, "..Simple braided copper cord with ends?" Yes! "No I don't have", suggested parts house. I said we only have an Auto zone now....so soldered on some lugs to extend what I have. The strap used in clamp has no ends.

Piddly stuff, kinda fun just modding the machine but don't have any pressing projects for it.

Was hoping to hear Disney had some luck getting his machine going? Doubtful issue but I did have breaker take a dump, one leg dead.

 

[Monkey Milk]

Got both machines, went though them and tighten up what needed and proceeded to cut some 1/2 steel plate at 45amp at 45psi. Both machines work perfect. I found out that too much pressure (90psi) causes too much blow back. Correct me if I'm wrong?

 

[wbrian63]

I've got mine all hooked up - pictures to follow shortly.

Since I typically won't be welding and cutting at the same time (as in never), I disconnected my 50' cord from the welder (replaced the original cord when I purchased the unit) and made an outlet box from a 6x6x4 junction box. Since these items come with a series of partially-punched 1/2 - 3/4 - 1" holes in 4 sides, I even took the time to weld those back in place. One outlet on the top for the welder, one on the bottom for the plasma cutter (couldn't do sides because of the proximity to the mig gas tank). Short section of original extension retained to replace the cord from the welder (naturally the original unit had gone missing), and two new plug ends for the welder and cutter.

Mounted the outlet box to the back of the welding cart and I'm all set for power.

Before firing it up, I checked the wiring for the switch at the nozzle and found no issues. I did add a small nut and bolt through the handle of the switch as another poster on this thread had done. I agree that the durability of the switch is in doubt if the lever doesn't bottom out against the barrel of the handle.

I did shorten the wires at the attachment point on the case - makes it more tidy and less likely to get caught on or by something.

Before I got the cutter, I purchased a Motor Guard M-60 filter from Amazon. There's a hole in the casting on the top that is just the right ID for a 5/16 tap, and so I tapped the casting. Added a mounting tab to the back of the welding cart next to the mig tank. Plumbed 1/2" copper into a T that feeds air to the filter - outlet of the filter goes to a Milton quick disconnect female adapter. Other outlet of the T goes down the side of the cart, along the base towards the front and across to the other side where I've added 2 more female fittings. Now I can hook up shop air to the cart and use short whips to power my pneumatic grinders without having to connect and disconnect all the time.

The inlet for the regulator I fashioned from a short section of old air hose with a male QD fitting on the end.

To test the cutter, I cut a couple of triangular pieces out of some 3/16 plate to make some gussets for shelf to hold the cutter on the welding cart.

Have a lot of learning to do regarding amps/pressure. First attempt was too few amps and that results in some really nasty blowback that will make you jump.

On the first gusset, I was a bit disappointed with the amount of dross on the back side of the cut. Took just a few seconds with a grinder to remove it and reveal a clean edge.

Then I remembered that others had commented that the dross was easily removed with a chipping hammer, so that's what I used on the 2nd piece. Clean as a whistle.

Now all I need is a small collection of 3/16 or 1/4" flat bar to use as straight edge guides for cutting.

I'm also not crazy about the ergonimics of the switch on the nozzle. I guess I'll get used to it.

Great tool - wish I had it years ago.

Thanks Moose for all your hard work on our behalf!!!

 

[Will S.]

AnEv942, thanks for your post, and pics. Some good ideas there, that I'm sure others will adopt.

wbrian: Thanks, too. Lots of good ideas there, and I'm anxious to see those pics.

And yes, again, thank you to Sean, for all your time and ongoing effort, that make this possibe.

Cable to replace what comes with the unit.

I see people replacing the cable that comes with the unit.

Some are using #10 and some #12.

Some are using SOOW and some are using SJOOW.

????????

The existing seems to be 2.5mm conductors. #10 would equate with that.

http://www.powerwerx.com/wiregauge.asp

The existing cable says 450A-750A. SJOOW is 300A and SOOW is 600A.

SJOOW is 3.84oz/FT and SOOW is 4.8oz/FT.

The #10 SOOW that I have is substantially heavier than the cord supplied with the unit.

What is the best choice for a fairly long cord (Say 30' or so)?

Is the 300A SJOOW adequate? It saves some weight but costs a very little bit more.

Bill

 

[littleponderosa]

wbrian63 - could you put up a photo of how you attached & plumbed in your motorguard filter. I'm nearly at loss without connecting it to the cart to keep everything clean & neat. Several different attempts did not look like what I was after.
Thanks
Bill

SJOOW is 300 VOLTS (not amps) and SOOW is 600 Volts. Both are more than adequate for a 220V machine (including safety factors, a SJOOW can handle brief voltage spikes of around 400V, and 300V regularly, so 220V is no problem). SOOW is usually more expensive than SJOOW. Odd that you can get SOOW for less than SJOOW

I'm a fan of SOOW over SJOOW simply because most SOOW tends to have a higher quality rubber outer sheath that is more flexible in both cold and normal weather, versus the usually cheap, hardish plastic covering a lot of SJOOW comes with. Having a nice flexible extension cord makes it much easier to use, rather than a stiff that never lays down or goes where you want it to.

Use this to calculate your AWG and length (http://buyextensioncord.com/info_voltage_drop.shtml). Voltage drop should be kept BELOW 3% for the best performance. You need to know how many amps your machine draws too (not how many it puts out, how many it draws from the wall, will probably be on a sticker somewhere on the machine), but other than that, it should be pretty easy to use. That way you can play around with gauge sizes and lengths.

 

[danscobra6]

This was not one of the group buy units, but it's a 110/220v 50 amp pilot arc plasma. I remounted the water trap on the side for easy access and it also keeps it away from the fan. Then threw some left over yellow on it. Don't laugh but for years the HF $1.99 filters have worked perfect. There are 2 air hoses coming off the compressor and one has a pre-plasma regulator and the same filter on it. Water is a big enemy to plasma cutting and with the 2 filters there has never been a drop or sign of moisture in the glass trap. Also very little restriction. I really think if you mount these on a cart it's nice to have everything attached to the cutter so you can pull it out and use it somewhere else. Dan

That is the main reason I choose SOOW. It can get quite cold up here and I hate having to fuss with a stiff cord.

 

[volleyball]

SOOW is cheaper for me as the distributor deals in volume on this and not SJOOW

Will S / LittlePonderosa - pictures as requested.

Here's the welding cart from the rear - you can see the outlet box on the left side of the tank. The welder plugs into the top, the plasma cutter plugs into the bottom. Inside the box, I have a 6-pole terminal block. I used some jumper clips to connect terminals 1 & 2 together, 3 & 4 together and 5 & 6 together. Power comes in from the cord - hots to 1 and 3, ground on 5. One socket attaches to 1, 3 & 5 opposite the cord connections, the other socket attaches to 2, 4 & 6. This way there's no jumpers from one socket to another.

The filter is mounted on the left side of the tank. I attached a 'T' that feeds air through the filter to the cutter, and also to a manifold on the front of the cart to attach tools.

As I noted previously, the filter (at least the one I bought) had a socket on the casting that was the perfect size for a 5/16-18 tap, so I tapped it, welded a tab to the welding cart and bolted the filter in place.

Here's the bottom of the filter - the socket here matches the one on the top:

And the path of the unfiltered air - down and across the side of the cart:

Under the front and up the side to a manifold where I can hook up 2 whips for grinders or whatever I need:

Hope this helps.

 

[littleponderosa]

Thanks for the assist. I've made some adjustments to the plan, will get you photos when I've completed the project.
I did decide to run an extra air line connection out for tools as you did. Didn't really think I needed to originally, but it only makes sense.
Thanks again
Bill

 

[Will S.]

Brian, thanks for posting those detailed pics. Good ideas, there. Nice setup. I have the same filter, but it is (for now), attached to the compressor, where I can connect to filtered air, or just to the manifold following the water sep, which I use for the air tools.

May 'borrow' some of your ideas, once I decide on a cart for the plasma cutter. No room on my welding cart for both.
