Do all Plasma cutters use air?
If so, Is there anyway to use a plasma cutter if your out on site at a job and don't have air?

I'm looking at buying the Supercut 50P but I am wondering how I could use it on a job site with no access to air...

Every plasma cutter I know of needs air. I would guess you need O/A cutting torch for job site. Maybe you could use large nitrogen tank with plasma? I don't know if it would work maybe someone smarter than me will chime in.

They all need regular air. You could use a portable 20gal 120v compressor.

I was thinking in welding class, the instructor had a plasma hooked up to a gas bottle. Maybe Nitrogen!?!? I could be wrong of course I'm never wrong.... :/

2 things I am thinking... If the cfm is low enough you can used compressed air... Like a scuba tank. Or better would be a small compressor.

Flip side is go oxy/acetylene.

It seems like you buy this and then you need that.... Sheeesh!! I'm gonna be broke by the time I've got all the crap I want!

What is the cfm needed for a Plasma.. or for the Supercut 50P Plasma?

Maybe Nitrogen!?!?

Ahh, You may have found a use for my lonely Nitrogen bottle!!!!! What does Nitrogen cost to refill???... Still think going to bottled air if you are going with a bottle.

yes buy a gas compressor from harbor freight or northern tool .

If it would work, I could make a portable air tank and just fill at the shop. Of course it would be a very limited window to cut

5.0 cfm at 70-90 psi have friend that got a gas compressor from harbor fright works good http://www.harborfreight.com/212-cc-9-gallon-135-psi-gas-powered-wheelbarrow-air-compressor-68140.html lol i need one of these for a back up compressor at my shop

I'm getting ready to buy a generator from Northern so the compressor has got to wait.... But, that's not a bad deal!
Next purchase after the generator is the Plasma cutter

What is the cfm needed for a Plasma.. or for the Supercut 50P Plasma?

Specs are 55-70 psi/ 3.5 cfm Pretty good quantity of air.

what size plasma do you have they show different air specs for what one it is

it would work for about a minute or so . my 50 will empty my 80 gallon tank fast know since forgot to turn my compressor on one day and it empty it really fast

CGCINC get the PowerPlasma 50. It will run circles around the SuperCut. IGBT is vastly superior. I had a SuperCut 50 and upgraded right away.

I have the powerplasma 50 but like the features on the powerplasma 60c also since low frequency so works for a cnc table = IGBT = is the way to go night and day difference in cutting and more durable than mossfets

What about the Blowback start? The Powerplasma 50 is the only one with that?
Also, I like the option of running on 110v just in case....The Powerplasma 50 says it's an option but what does that mean?

Blowback is a nice feature for CNC, no HF to mess up the electronics and no lag in transfer. Also to blow holes in things, a lot of power all at once. The Trafimet S45 is a nice torch (and harbor freight sells the consumables for it too; so consumables local for most US customers even on the weekend).

"I'm" not and never will be a fan of 110/15-20amps stuff, but waiting on the 160STH (new Duncan idea I think I will like; should have it in a couple weeks) maybe change my mind on the 110volt stuff.

A PP50 on 110vac, might work OK. But that would be the only thing we make I would use on 110.

If you plan on JOB SITE work, I would go IGBT. The MOSFET machines will work, but go bigger if you are getting paid for the work. On the compressor, see if you can find a 3.5CFM @ 90 PSI compressor, that will run it fine. And plan on a good water filter, not trap. The silicon ones work well if you are on a budget (desiccant type) .

I saw prices for consumables, and it seems, S45 (blowback) consumables are more expensive than for A81 (HF). IMHO, the difference is compensated by cutter's price if we are talking about hobbyists, but it might be a reason to choose HF by professional fabricators.
