3. Move tension knob up. Then move ten-
sion arm away from wire feed roller (see
Figure 12).
4. Remove end of wire from spool while pinch-
ing roll to prevent unraveling. Cut bent end
of spool. Slide wire through wire guide along
wire drive roller and into wire housing (see
Figure 12).
Generally speaking, the size of wire should be
changed depending on what thickness of metal is
being welded on. Use 0.030" wire for thinner met-
als and 0.035" for thicker metals. Wire thickness
primarily affects the depositional rate of the con-
sumable metal/amperage, so machine settings
may also need to be adjusted if the wire size has
been changed.
To install/change wire:
5. Remove wire drive roller by twisting cap
counterclockwise. Lift up to remove cap with
wire drive roller.
7. Install wire drive roller so desired slot is on
top, and reattach it to machine with wire drive
roller cap.
8. Move tension arm against wire, then flip ten-
sion knob down to secure tension arm in
place (see
Figure 14).

6. Compare gauge of wire to slots in wire drive
roller to determine which slot fits best. Large
wire groove fits 0.035" flux-cored wire, and
small groove fits 0.030" flux-cored wire (see
Figure 13).
