Greetings all,
First of all, this machine is GREAT! The control in AC with the pulser is incredible. After some initial problems with torches,(We did not need the
700 amp rated torch that came with the machine, 250 is working just fine. Add to that the reluctance of our tool room guy to buy the correct set up, we attempted to "Frankenstein" a set up together, need I tell you how that worked out?) We are now rolling right along with one of the smaller 250 amp Miller torches and life is mostly good.Now for the question; When welding in DC, usually SS, I can not keep a decent point on my tungsten. 3/32" 2% Thoriated tungsten, ground to "pencil point" erodes like crazy, a simple 1 to 1 1/2X diameter or so grind yields a slightly longer lifetime, but it tends to ball slightly and I lose alot of arc control. Running DCEN with or without pulser doesn't seem to matter.
So, any ideas? Am I missing something in the directions or use of the machine? As always, any and all help is greatly appreciated.
Regards, Jim
