What size wire do you run to have good luck with the HF 90A? I once had one, a blue #94056 and after some frustration concluded it could do good work only in a narrow range of material thickness and settings, and must have been designed for shop fabrication or something where the application never changed. I've read that the more recent black ones are much better. I finally replaced mine with a Century 110v DC welder with similar specs, it was night and day better. What's your secret, to get good luck with the HF 90A?
I have the old blue 90A version that is hot all the time it is on. I run .035" wire with the best luck and most forgiveness... I've done a fair amount of welding 1/8" material with great success down to sheet metal, welded the 3" channel iron bumper on a small trailer and it's very attached...
