Finally got my replacement out and fired it up. Good to go, cuts like butter.

Just head back from Aquamoose. He too was unable to repair my unit with replacement parts. Glad to know it isn't me, sad that I spent $100 on shipping to get a replacement.

Used in a CH siphon blaster and it worked out really well. at $6.99/50lbs, it is by far the cheapest media I've found. Just be sure that what you are getting is small enough to not clog the gun. I got two bags, one medium and one rough ground, the latter being too big. As a bonus, this stuff...

sent back for replacement.

Awesome! I've got a siphon blaster as well, so I'll give it a shot. I've been thinking about rigging a bucket to my palm sander to keep the media agitated and aid pickup.

they list it as barn lime, used for neutralizing the acids from waste and making soil generally better PH balanced to support plant growth.

everything was nice and tight on the lugs, ground and torch side.

I know the standard is sodium bicarbonate, but I am unable to find it in bulk. I can however, get Calcium Bicarbonate from TSC for $3/50lbs. The hardness is 3 on the Mohs scale compared to 2.5 for sodium bicarbonate, so I don't think that will be a problem. I'm looking to blast some aluminum...

i checked it and adjusted to .03-.04

I checked the FETs on the bottom, all are open positive probe in the middle, negative to the sides. i did not find any diodes that were short.

Ok, I adjusted the gap to .040 and it is still going OC. It will run the pilot all day, but as soon as it jumps to the ground, it goes OC.

Any other thoughts?

10.8ohms torch tip to ground clamp. Open from torch to case ground. Open from clamp to case ground. I did check under the insulation and it is not shorted. I did disconnect the temp sensor at the board, not desolder the sensor.

Also it is open when powered on, but 18.24M after tripping And it still trips with the sensor disconnected.

Light stays lit until I turn off the power and turn on again. Fan comes on immediately on power. Resistance goes to open(capacitor charging?) when probed. I disconnected the sensor at the board and it is open.

Does not appear to be short

I tried mine out tonight for the first time. I turn it on, and get the pilot arc, but when I cut, the OC light comes on quickly. I checked the ground and it is good. I was able to get about a 10 second cut, but that is the best I could manage. thoughts?

I haven't found a decent deal in Tallahassee, FL in years.

My 8th grade math teacher related this one to me: When he was in chemistry class in high school, they were reviewing the distillation of alcohol. The teacher had a large still setup on the front bench which was distilling through the class. At the end of the class, he had a small beaker of...
