/diy/ - Do It Yourself

>>1271292
i'm not a welder, just an ME with some basic knowledge. i was curious though so i googled around. there's not much available in objective technical terms (see pic related, fucking "buttery") but it seems that square waves penetrate better and aren't susceptible to losing the arc at zero voltage crossing. a triac dimmed waveform will be different though. you'll have long dead periods on most settings where i guess the arc could die and then be reignited by the sudden spike at turn-on a few ms later. so you might get a unique flickering effect. i have no doubt that triac controlled diy welders are properly documented somewhere though so you don't have to listen to my retarded speculation.
