CONTROLS AND SETTINGS

This machine has the following controls:
(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
procedure based on type of material and thickness being
welded.
3. WIRE FEED SPEED CONTROL (WFS) – The knob sets the
speed that the machine feeds wire. Along with arc voltage
this control sets a weld procedure. Refer to the procedure
decal on the inside wire drive compartment door to set a cor-
rect welding procedure based on type of material and thick-
ness being welded.
(See Figure B.2)
4. GUN TRIGGER – Pressing the trigger activates the wire drive
to feed wire and energizes the output of the machine. Press
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 nozzle protects
the mounting threads on the gun. When MIG welding the
copper 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 receptacle.
