Step 1: Select proper wire feed roller according to the welding wire diameter
1) Release two preload adjustable press rods;
2) Unscrew the nut of wire feed roller and remove it;
3) Replace with proper wire feed roller, put the side of the corresponding wire feeding trough facing
inward, and then tighten the nut.
Step 2: Install the wire spool. Note that the welding wire must be led out from the wire spool, insert the
wire spool on the spool shaft, and pass the welding wire through the wire feed roller. The welding wire
must be placed in the slot and then clamped. The welding wire should be ordinary welding wire ranging
from 5 kg to 25 kg, but flux-cored wire should not be used.
Step 3: Adjust the press rod pressure to stably send out the welding wire.
4.5.2 Wire feeder connection
Figure 4-3 Assembling of wire feeding brass nozzle
Step 1: Connect the wire conduit. Loosen the locking screw to insert the brass nozzle of the wire conduit
onto the wire feeder, pass the welding wire through the brass nozzle and tighten the screw fixing the
brass nozzle.
Step 2: Assemble the wire conduit on the torch head bracket and tighten the nut; adjust the length of wire
conduit to extend to the welding brass nozzle.
Step 3: Connect the control line of the wire feeder. Insert the 7-pin connector plug of the control line into
the 7-core socket on the rear panel of the wire feeder and tighten it. Then, insert the other end into the
wire feeder interface on the rear panel of the machine.
