Installing The Wire - MasterCraft MIG 180 Instruction Manual

Installing the wire

WARNING!
Potential hazard that could result in serious injury or loss of life.
• Always switch the power OFF and unplug the power cord from the AC power
source before installing the wire.
• Remove rusty wire or rusty wire spool.
• Do not weld work pieces that are thinner than 24 gauge. The welding unit is
not designed to do so. Doing so may burn the work piece.
• Before installing, remove the old wire from the MIG gun assembly to prevent
the wire from being jammed inside the gun liner.
• Do not remove the welding nozzle when the MIG gun trigger is pulled due to risk
of an electric shock. Turn the power OFF before removing the welding nozzle.
Refer to the chart below for wire selection based on type of welding:
Welding Type
MIG welding
Flux-core welding
Note: MIG wire can be either mild steel,
stainless steel, or aluminium solid wire.
1. Remove the nozzle (1) and contact tip (2)
from the end of the MIG gun assembly
(fig 1Y)
.
Note: Ensure that the groove on the drive roll
matches with the size of the wire being
installed.
2. Unwrap the wire spool from its
packaging and do not unhook the wire
from the spool at this time.
3. Remove the wing nut, bushing and
washer from the hub in the wire
compartment.
Note: If a 4" spool is used, proceed to step 4
and then follow step 7. If an 8" spool is used,
skip to step 5.
