Turn off the air and try to cut, If you get a spark from the tip to the material as you hold the torch about 1/16" from the piece and pull the trigger. Pilot arc..

The model of unit determines if it can weld. Models 40-50 etc. Are p-cutters only. Models 320-420-520 etc. are welder capable. 50 amp P-cutter, 150 amp DC Tig, 120 amp Arc in one machine..

One the tip is inside the shield,The other is sticking pass...You can drag a non-drag one, But it doesn't last as long,, Plus it will stick sometimes..And yes water will mess up your tip...



and here's the non drag shield..

Mine will not lite up if the tip is bad or you have no air.. If everything is ready to go.. It will light up as soon as I pull the triger, Now if it's not close to the steel.. It won't stay lit very long.. And once I'm done cutting with it.. The air will keep running for a little while to cool down the tip..

so basicly with the drag tip the shield keeps the tip from touching the work and the shield makes the contact....I think I got it...
and with the pilot arc the arc is internal like a pilot light in a water heater and the tip doesnt have to touch the workpiece to fire up....
I want to thank everyone for all the help making me understand how these work and the different types...
I could see right away how handy this is going to be for making all sorts of brackets I used my cutting torches to make everything when I installed my rearend and again when I installed the air bag suspension. I must have spent days grinding the rough edges left from the torch and they never did look quite right but everything worked so I just went on to something else now I may have to go backwards once again and do it all over ,it shouldnt take long at all..

Ok,so I've been playing around with this p cutter Im amazed at how quick it burns spot welds I can burn through 1 layer or 2 layers of sheetmetal and leave a layer it all depends on the amperage and air pressure,,,,So Now I have a question for the guys that use them all the time....

question:when cutting sheetmetal should the machine be set at the lowest amperage that cuts whats needed or should it be set all the way up with the air at max too? How do you know where to set the amps and air at..
I saw a vid that says the air pressure should be at 70 psi ...sounds like a lot of pressure, I can cut with about half that and just to burn one layer of sheetmetal all I need is 13 amps and 15-20 psi....can you have too much air and not enough amps or viceaversa...
Today I will cut up the old roof skin I'm replacing and Im going to cut off all the lips on all four sides so I can store the metal for future use...I'll be making a guide that runs along the edge and also keeps the tip from touching...these are some long 5-6' cuts and I dont really want to warp it so I'm figuring the lowest amps that cut (25 A) and about 30 psi

I keep my air around 45 psi most of the time and amps at 20-25 for general sheet metal work. Then turn it up for heavy steel plate. I have never had to use over 60 psi air, even in the 1/2" or thicker.

so what determines how smooth the sides of a cut come out in the thicker steel ? lets say 3/8 -1/2"

Cutting speed has a lot to do with quality of cut and amount of slag on the back side. Experience

I bought the software for a p-cutting table setup.. Plan on building the table this winter. Have a spare computer. Adapt the torch to fit and Ebay has complete stepper motor setups very reasonable. This spring I hope to have it up and running.

I leave my internal regulator at 60psi all the time. I do turn down the amperage for sheet metal but I don't recall having an amp reading on the gauge. For thin sheetmetal, you should have the air and amperage set high enough to walk along at a steady pace. It shouldn't take more than 30 seconds to cut 6 ft. The higher air pressure clears the curf and cools the metal quickly and avoids warping. Go too slow and it will warp...

That makes a lot of sense you guys ....I may be to old to keep up with this bad boy ....I'll tell ya what, I'm getting good at these spot welds now. Today I went around and drilled out all the holes I made with a 5/16 drill just to pretty them up ,it only took a min and they look they were drilled...I'm totally floored with this thing....It makes me sick though ,thinkling about all the money I could have saved (and made) if I got one five years ago when I was thinking about it...
I found one spot weld I missed and I had the drill in my hand but insted of drilling one dang hole I disconnected the air,got the P cutter, hooked it all up and blew out the hole.I had to laugh at myself, It sure didnt take long for me to get spoiled...

Just pulled the trigger on a TIG welder !!
I've been watching the Eastwood 200 AC/DC for a while waiting for the price to drop even more than the 50 bucks it was reduced a while back. Well today they marked it down another $50. $800 and FREE shipping (gotta be FRUGAL)to get introduced to TIG...
