I am just messing around with some 1/8 & 1/4 mild steel, using a red band tungsten, DCEN. Any of the calculators that I look at and also the manuals say I should be using about 200 amps or so for the 1/4".
I started out at about 125 amps with the 1/8 and found that it really heated and melted the steel. The whole thing was glowing red including the tungsten.
So...I kept turning it down and trying it.
Basically now I am down to about 65 amps on the digital readout, using 1/4" mild steel and it's not working too bad but I think it should be much better than what I am getting.
I am hoping and based on what I have been reading here is a few of you could offer me some advice on what I could be doing wrong.
Looking forward to your posts...
