COMPACT WIRE WELDERS
CONTROLS AND SETTINGS
See Figure B.1
1. POWER SWITCH – Turns power on and off to the
machine.
2. ARC VOLTAGE CONTROL – This knob sets the
output voltage of the machine. Along with wire feed
speed (WFS) this control sets a weld procedure.
Refer to the procedure decal on the inside wire drive
compartment door to set a correct welding proce-
dure based on type of material and thickness being
welded.
NOTE: The Arc Voltage Control will be either a contin-
uous control or a multi-position switch depend-
ing on the model.
3. WIRE FEED SPEED CONTROL (WFS) – The knob
sets the speed that the machine feeds wire. Along
with arc voltage control this control sets a weld pro-
cedure. Refer to the procedure decal on the inside
wire drive compartment door to set a correct welding
procedure based on type of material and thickness
being welded.
See Figure B.2
4. GUN TRIGGER – Depress the trigger to activates
the wire drive to feed wire and energizes the output
of the machine. Depress the trigger to weld and
release the trigger to stop welding.
5. WELDING GUN – Delivers wire and welding current
to the weld.
a. Gun Liner – wire travels through the liner from the
wire drive. The gun liner will feed .025” to .035”
(0.6mm to 0.9mm) wire. The 180A machine can
weld with .045”(1.1mm) wire if an optional
.045”(1.1mm) liner is installed in the gun.
b. Contact Tip – provides electrical contact to the
wire.
c. Nozzle – When flux-cored welding the black noz-
zle protects the mounting threads on the gun.
When MIG welding the brass nozzle funnels the
shielding gas to the weld.
6. WORK CLAMP & CABLE – Clamps to the work
piece being welded and completes the electrical
welding circuit.
7. GUN TRIGGER CONNECTOR RECEPTACLE –
Plug the 4 pin gun trigger connector into this recep-
tacle.
