Ok Ive already posted a few times about my new machine, just very very new with this and please dont tear me open when i ask what im about to ask. I already have NOOB written on my forehead
ANyways so i was excited to start on a new project making steel shooting targets out of 3/8 AR500. Well since that stuff is $$$ I decided to start out with a plate of just 3/8" mild steel. (think they call it AS36?) anyways got home all excited and powered it up for a test run. I would have been better off taking a lighter to that steel... (overexagerated) but it just wouldnt peirce it all the way through and when it did it took repeated passes. After 20 minutes of playing with it and ruining my consumables with all the back splash of slag i got i gave up and assumed the 50 amps werent strong enough to get through it. Then I saw peoples videos with the same machine on youttube blowing through 1/2" steel with 40 amps like it was butter! Whats goin on!?!
Ive looked for stickys on the psi/amperage settings and didnt see much, and the owners manual didnt help after a quick scan. Can anyone tell me what im doin wrong? I was running it on about 42amps with the psi from 80-100. Im getting the feeling im not getting enough air pressure from my compressor but the main gage never dropped the whole time. Its just a 20 gallon 1.5 horse 150psi but surely it could handle cutting for a few seconds.
Also here comes the newb question. Do you need the ground clamp for this machine. I just realized I wasnt using it but it still was melting away. Im going to feel like an idiot if the answer is yes but i though that maybe the pilot arc was taking its place since u dont use that when you tig and stick. Thanks for whoever helps me on this. I really appreciate it.
