I have a TIG syncrowave 250dx which i bought used about a month ago. At this point i am fairly proficient with mild steel and i am trying to weld aluminum. 1/4" thick alum strips. No matter what i do the weld sounds really off, the arc constantly wanders, the tip really ***** up fast and it's impossible to make any real weld with it. Any ideas?
I have used pure tungsten and 1.5% lanthanated tungsten. Machine is set to AC. Post flow at 9 seconds, balance at 4, and HF at 20-60. HF cont. is also set correctly. 100% argon set to 19cfm.
At this point i am beginning to think something is wrong with my machine. Any ideas? If my settings sound right what malfunction on the machine's side would cause this to happen?
