Powering a 230V Welder with Generator ... Question

[Tim_in_NC]

Hi Guys,

I'm looking to purchase a Hobart 190 Welder ... It's a 230V unit.

I want to use my Generator to power it when welding.

My Generator is a Generac XP8000E Unit.

It has a 240V out with 30 amps ...

I want have any issues running this welder from this generator will I ???

Here's what the Generator Manual States:

"120/240 Volt AC, 30 Amp Locking Receptacle – Supplies electrical power for the operation of 120 and/or 240 Volt AC, 30 Amp, single-phase, 60 Hz, electrical lighting, appliance, tool and motor loads."

Here are the specs for the Welder:

"Input Voltage : 230 V | Weld Thickness : 24 ga.- 5/16 inch - Single Pass | Duty Cycle : 30% @ 130 A"

Just wanted to make sure all is good from the more electrically inclined fellas ...



Thanks

What's the amp draw on the welder

 

[Tim_in_NC]

I found the following:

Welds 24 ga. up to 5/16 in. mild steel in a single pass
Operates off 230V input power
7 voltage settings for fine control and improved arc performance
25 to 190 output amperage
Duty cycle - 30% at 130 amps
Durable feed head with quick-release drive roll lever - easy accessibility to thread new wire
Dual groove, quick change drive roll
Self-resetting thermal overload system protection
Built-in contactor eases use and is an excellent safety feature which makes wire electrically "cold" when not welding
Manufacturers limited warranty

There should be something that says the draw, such as 40 or 50 amps, I believe what you posted is the current the welder makes to make the welds. Most big welder a are 50 amps. What does the plug look like that comes off the welder,there should be a nema label on it.

I looked on northern tools and if that correct then that's a welder that gets hooked right into the feed coming into the panel, does say 130 amps which your gen would never do.

Just noticed it's dc voltage and not ac.

One of the reviews says 30 amps so then you should be ok with the gen

 

[Tim_in_NC]

Yea ... just read one of the question from a review ... and a response was that the input amperage is 20.5 and a 30 amp breaker is recommended ...

Looks like I should be ok with the generator running the welder ...

Thanks guys.

It says input 20.5 amps right on the specifications tab on the Hobart site for the 190.

Yea ... we figured that out ... thanks

Are you looking to use it where there is no power or do you just not have 240V where you need to use it? I think the next step up is the 210 mvp, it will run on either 120v or 240v, might be worth it if you don't have to drag out a gennie every time you want to make a quick weld.

I'll mainly be using out where 240 isn't available ... no problem breaking out the generator ...

Thanks

230 v     kva          kw
20.5      4.7          3.88

It appears you will be OK.

Most big welder a are 50 amps.

It is true that most big welders are equipped with a 50 amp rated plug. That is just the standard and has nothing to do with what the welder needs. Many folks would avoid buying a welder if it had a special non standard plug to correspond with the lower required amperage.

You'll notice those big welders using the 50 amp plug have a very small, like 12 gauge, cord.

I've run my 240 amp lincoln tombstone welder with a 6500 watt genset to build up grouser pads on a dozer in the field. You notice it when you first strike the arc but then for the rest of the bead the genset power is fine.

Oh and the weld voltage is in the 25 volt range. So 100 amps is 2500 watts output and you must assume the welder has an efficiency loss of 10% or so.

just my ten cents but i would want 40 amp out of the genny to give constant 20a on the welder because of the inrush on the welder transformer when you strike
