Help. I've been working this all morning up to 3:00 this afternoon. I'm tig welding square tubing into a frame for a gate. Tubing is steel .120 wall. Tungsten is 3/32 orange band (ceriated?). Straight Argon at 11 to 15 cfm. All joints are square and tight. I've sanded off any scale (actually, all surface around joint) and I'm cleaning with laquer thinner all around and IN the tube as well.
What the F**K? Even my filler (er70s2) is clean. I've reground tungsten too many times. Probably started with 7" and down to 5". I keep getting contaminants where the tungsten appears to be eroding and turning a slight (burned?) color. The weld puddle is bubbling before my eyes leaving some porosity behind. I'm keeping the tung out of the puddle and probably somewhere around 1/8 to 3/16 from the work. I'm even seeing sparks at some points.
I could just Mig the **** thing, but I don't want to give in. I'm determined to get done with TIG.
The "lift arc" has been a source of trouble for me. I have a syncro 250 and it seems everytime I use the lift arc I can feel the tungsten fuse to the work and I'm positive it's pulling off a tiny piece of steel. What other technique do people recommend? By the way, I barely touch the tung to the work and it fuses. Help syncrowave users!!!!
Any help out there?
