Specs

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.

Econotig®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.
