Hi to all.. I have been trying to practice wTig welding Aluminum using my Dialarc machine on AC. I am using Argon with a brown (tungsten and Zirconia) electrode ball shaped. I don't have access to a constant voltage machine right now. I am having a terrible time starting the arc. The weldament is clean and I run a SS brush over it before proceeding.
Any suggestions... or should I give up and buy a machine with Hi frequency???
Its possible to do..but damned damned hard to do without HF.
You can pick up a HF box that would sit on top of your welding machine...
or you could do as I do..and simply not tig aluminum with a tig rigged stick machine. I recently swapped up for an absolutely beautiful and mint older Cobra Heavy Duty Mig spool gun (has water coolant of the mig hose etc ) and and am using it for aluminum on top of one of my Miller 35s.
Im not a welder, nor do I play one on TV..sigh...but it really takes a proper HF tig machine to weld aluminum. Or a spool gun/mig
Or even stick
'In the first place, we should insist that if the immigrant who comes here in good faith becomes an American and assimilates himself to us, he shall be treated on an exact equality with everyone else, for it is an outrage to discriminate against any such man because of creed, or birthplace, or origin. But this is predicated upon the person's becoming in every facet an American, and nothing but an American... There can be no divided allegiance here. Any man who says he is an American, but something else also, isn't an American at all. We have room for but one flag, the American flag... We have room for but one language here, and that is the English language.. and we have room for but one sole loyalty and that is a loyalty to the American people.' Theodore Ro osevelt 1907
Thanks for the great advice from all of you. I am obviously using the wrong equipment for aluminum. I guess I had better start saving my pennies for an Inverter or a Synchrowave maybe. gunner suggested a HF add-on , I wonder will this adapt to my Dialarc, I must check that out.
Also Gunner...I like your quote from Thedore Rosevelt...It applies here in Canada as well....
