Adjusting
Wire Feed Tension
Wire feed tension must be set properly to ensure
that the welding wire feeds correctly during weld-
ing operations.
To adjust wire feed tension:
1. DISCONNECT MACHINE FROM POWER!
2. Slide latch back to lift top cover and expose
installed wire spool and wire feed driver (see
Assembly on Page 16).

Note: Wire tension should be tight enough to
prevent wire from slipping in driver wheel, but
not so tight that it cannot feed through assem-
bly smoothly. If wire tension is too low, it can
cause wire spool to unravel.
5. Once desired wire tension is achieved, close
top cover of machine.
3. Use wire tension knob to adjust wire tension.
Turn knob clockwise to increase tension, and
counterclockwise to decrease tension.
4. Hand-tighten wire spool nut to apply tension
to wire spool (see
Figure 19). Spool should
spin freely when wire is being fed through
machine, but immediately stop after letting go
of trigger to prevent unraveling.
