Upgraded circuitry gives you finer TIG output
adjustment with the remote foot or fingertip
control. If you need more output while using
the remote control, simply increase the
setting of the front panel amperage control.

Arc Welding
Power Source
Issued April 2003 • Index No. AD/1.2
AC output for superior aluminum welding
and DC output for mild and stainless steel.
Four-position polarity
and range selector
switch
offers two AC
current ranges, DC
electrode (–) for TIG,
and DC electrode (+)
for Stick.
Special arc starting
circuitry eliminates
high- frequency starts.
Built-in arc assist starter
for DC TIG.
Built-in arc assist stabilizer
for AC TIG on aluminum.
Process switch automatically
sets machine for TIG or Stick.
Unique “flow-through” shielding
gas TIG torch connection allows
removal of torch without tools.
The Power of Blue®.
Power source is warranted for 3 years, parts and labor.
Original main power rectified parts are warranted for 5 years.
