Assembly
MIG Welder Unit
1. Assemble the Axle (30) and Wheels (29) as illustrated in the Wheel Assembly Drawing
at the end of this manual.
2. Place the second wheel over the end of the Axle and secure in place with the Axle
locking clip.
3. Insert the Handle (4) into the Handle Sockets (3) and mount the Handle Sockets to
the Side Panel B (1) top using supplied hardware.
Note: The Handle (4) configuration may differ slightly than what is shown in this manual.
4. Lift Side Panel B (1) all the way to expose the wire spool and Wire Feed Mechanism
(11).
5. Remove the Nut from the Wire Spool Axle (10). Place the Wire Spool over the Axle
with the wire exiting the spool over the top. Refer to photos above. Replace the Spool
Axle Nut.
6. Open the Wire Feed Mechanism (11) as shown in the photo (top-right).
7. Feed and guide the spool wire into the Wire Feed Mechanism, past the feed wheels
(C), and into the Welding Torch / Cable (16).
It will help if the Welding Torch / Cable (16) is straightened out as much as possible.
Push in until the wire comes out the Welding Torch head. If it cannot be fed manually
all the way out, it can be fed automatically when the welding unit is powered up.
8. Close the Feed Mechanism (11) over the wire, and adjust the feed tension (D) if
necessary.
9. Check that +/– cables to connection Knobs (34) are correct. See photo (top-left).
When using non-flux wire and protective gas, connect wire cables as shown in photo.
For flux cored wire, no gas is required. Reverse cable connections.
