We used the Primeweld machines at work and they are good for home use.. not welding all day. We have 8 machines, every one of them had the motherboard go out before the year was up.

I'm struggling with arc start. Even on a brand new tungsten sharpened with a special tool. I maintain the Gap and not even introducing filler rod yet, I just struggle with getting the puddle started. I thought it was an issue with the spark gap inside the machine so I went and swapped it at harbor freight and got the same results with the new machine

@whoknows3347 ya my father was mostly impressed doing ac on 6061 aluminum Just could not believe how clean the cleaning cycle was and how smooth it welded I could not tell you the difference I’m just a novice lol and he is not easily impressed with anything so I was really happy about it
