Controls and Operational Features
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.
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 0.6mm to
0.9mm wire. The PM180C machine can weld
with 1.1mm wire if an optional 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 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
receptacle.
8. WELDING GUN CONNECTOR BUSHING &
THUMBSCREW: Provides electrical power to the
welding gun. The thumbscrew holds the welding
gun into the connector block (Front of Machine, Side
Door and Wire Drive Cover have been removed for
clarity of Items 8 and 9).
9. OUTPUT TERMINALS: These connections allow to
change the welding polarity of the machine
depending on whether you are MIG welding or flux-
cored welding.
10. WIRE SPOOL SPINDLE AND BRAKE: Turns
Holds a 102mm diameter spool. Use the 51mm
spindle adapter included with the machine to use
203mm diameter spools. The thumbscrew sets the
brake friction to prevent the spool from over rotating
when the trigger is released.
11. WIRE DRIVE & COMPONENTS: Feeds wire from
the wire spool through the drive and through the
welding gun to the weld.
