5. Thread wire to gun as follows:

a. Round o the free end of the welding wire with a le.

b. Release the tension lever to relieve pressure on the feed rolls. Rotate pressure adjusting knob o the pres-

sure roll bogey and lift bogey upward to access the feed rolls.

c. Thread the wire through the inlet guide, over the feed roll grooves in the feed rolls, and into the outlet

guide.

d. Lower the pressure roll bogey to engage the wire making sure the wire is seated in both the lower and upper

feed roll grooves.

e. Remove nozzle and contact tip from the gun. Turn on the Power Source using the main power switch and

then turn on the DuraDrive feeder by moving the Power Toggle switch to the "ON" position Inch the wire

using the DuraDrive jog switch until the wire exits from the front end of gun. Thread the contact tip over the

wire and tighten in tip adapter. Replace gun nozzle.

6. When wire coils are to be used, raise the spindle assembly to its highest mounting position in the spindle post.

Mount the wire reel onto the spindle as though it were a spool (see 1 and 3 above). Remove wing nuts and cover

plate from reel. Remove coil from its package, but do not remove its bind ing wires or straps. Slide coil onto reel

so that wire will be drawn from bottom of coil (starting end for a coil is always the outer end). Replace reel cover

plate and wing nuts. Cut o coil tie wires. Adjust brake screw and thread wire to the gun as covered in 4 and 5

above.

F. ADJUSTING THE PRESSURE ROLL ASSEMBLY

When a new wire size or type installed, set the pressure adjustment as follows:

1. Unscrew the pressure adjustment knob until the pressure knob is free.

2. Alternately press and release the gun trigger switch while slowly tightening the pressure adjusting knob until the

wire begins to feed with out slipping. The pressure applied should be the minimum required to provide positive,

nonslip wire feed. Too little pressure will result in wire slippage while ex cessive pressure will scar and deform the

wire.
