Chicago Electric MIG 170 Owner's Manual & Safety Instructions page 12

IMPORTANT:
Securely hold onto the end of the
welding wire and keep tension on
it during the following steps.
If this is not done, the welding wire
will unravel and create a tangled
"bird's nest", wasting wire.
9. Cut off all bent and crimped wire.
The cut end must have no burrs or
sharp edges; cut again if needed.
10. Keep tension on the wire and guide at least
12 inches of wire into the Wire Liners.
11. Swing the wire feed swing arm down, and swing
the feed tensioner up to latch it across the tip of
the arm. Make sure the Welding Wire is resting in
the bottom groove of the Feed Roller, then turn the
feed tensioner knob clockwise a couple of turns.
After the wire is held by the tensioner,
you may release it.
12. Pull the Nozzle to remove it.
13. Using the third oval hole on the Multi-wrench, turn
the Contact Tip counterclockwise and remove.
14. Lay the Torch Cable out in a straight line so that
the wire moves through it easily. Leave the cover
open, so that the feed mechanism can be observed.
