My neighbor got one of those cheap Harbor Freight TIG welders
recently. I've never TIG welded at all, but since I have more
experience welding than him (stick, MIG) he wanted me to see
if I could get the thing going for him.
If you're not familiar with these inverter TIG machines, they
are very stripped down. There are three LEDs on the front panel,
one each for "power," "welding," and "over heat." When I try to
get an arc going the "welding" LED comes on and stays on indefinitely.
You can hear the gas solenoid open up when the light comes on,
but it stays open indefinitely as well. According to the poorly
translated manual the "welding" LED should go off automatically
after the arc is broken and the gas solenoid should shut off.
The other problem is that I can't get an arc going. Bringing
the tungsten down to the work causes a tiny spark, and that's
all. No amount of scratching, tapping, or carefully lowering
the torch will start an arc at any power level setting.
Since I have absolutely zero experience with a TIG welder
it's hard to tell how much of this is my fault and/or
how much is the machine's.
Any enlightening comments you may have will be greatly appreciated!
