Power Control Switch

Trigger Hold Switch
Trigger hold allows operator to weld without
holding gun trigger.
To use trigger hold function, place trigger
hold switch in the ON position.
The operator must hold the trigger for a mini-
mum of 2 seconds, but no longer than 6 sec-
onds before releasing it. Welding will contin-
ue when trigger is released.
To stop welding, press and release the trig-
ger.

Jog/Purge Switch
Pressing the Jog switch allows the operator
to jog wire without energizing the contactor
or gas valve.
Pressing the Purge switch allows the opera-
tor to purge gas lines before welding and to
preset gas flow rate at the flowmeter.
4
Wire Speed Control
Use control to adjust wire speed within the
speed range selected by the wire speed
range switch, located on the inner control
panel. Maximum wire speed may be limited
by arc voltage.
When using wire speed dual schedule, the
reduced wire speed will be 87.5% of the
standard wire speed− See Section 6-3.
5
CC/CV Switch
Use switch to match feeder with the output of
the power source.
While welding in CC mode, actual wire speed
is dependent on arc voltage.
While welding in CV mode, the wire feeder
remains at constant speed and the wire
speed is not dependent on arc voltage. Max-
imum wire speed may be limited by arc
voltage.
6
HI/LO Speed Range Switch
Use switch to select speed range. High
range is 100 to 800 Inches per Minute (2.5 to
20.3 Meters per Minute). Low range is 25 to
200 Inches per Minute (0.6 to 5.1 Meters per
Minute).

Soft Start Switch
The Soft Start feature provides a smooth
start during most weld conditions. When the
trigger is pulled, the wire speed is approxi-
mately 50% of the weld wire speed, as set by
the wire speed control knob. After an arc is
established, the wire speed increases to the
weld wire speed.
When using small diameters wire, or with in-
verter power sources, it may be necessary to
turn soft start off to obtain smooth starts.
After adjusting the switches, close and latch
the door before welding.
