I know, i just never experienced such a consistent surge with a dirty tungsten. Not saying it couldn't happen, just not understanding completely how it works.

I kind of agree. Looked like it could have been a number of things mentioned, IMO. But the latest welds he posted look pretty darn good. If I can get aluminum welds like that when my welder gets here I'll be doing the snoopy dance! ;)

sorry for the misunderstanding , i think the probleme was cause mainly by a dirty tungsten. why it was dirty was because i was low on argon when i first got the machine and turn down the post flow way to low so my tungsten was building up a layer of oxide on the tip when i arc off( colored tungsten tips ). i tought this would not do much but turns out its a huge deal when running 100amp or less on AC at 30% balance. how i find out is that when i received my new argon botlle i did all the stupid check and made sure everything was perfect, take the time to grind a good tip on my tungsten , then i ran a first bead which layed down perfect, no issue till the post flow stop too soon and my tip got blue, try an other bead right after and the trouble reappears, resharpen the tungsten trouble disapear. so im pretty sure its that . I did by the way play with the point gap on the HF board, it was a bit too much open , but i dont think this was an issue cause the HF is only used on start up and it was fine before i play with it. maybe its because its an entry level welder with basic circuitry but any way as long as i baby my tungsten i think ill be fine
