PROCEDURE TO INSTALL DRIVE ROLLS AND WIRE GUIDES
WARNING
•ELECTRIC SHOCK CAN KILL.
•Turn off input power at the welding power source before installation or changing drive roll and/or wire guides.
•Do not touch electrically live parts such as the wire drive or internal wiring.
•When feeding with the gun trigger, the electrode and wire drive mechanism are "hot" to work and ground and could remain energized several sec- onds after the gun trigger is released.
•Only qualified personnel should perform this operation.
1.Turn OFF the welding power source.
2.Open the
3.Remove the outer wire guide by turning the knurled thumbscrews
4.Rotate the triangular shaped drive roll retaining mechanism to unlock the drive rolls and remove the drive rolls.
5.Remove the inner wire guide.
6.Insert the new inner wire guide, groove side out, over the two locating pins in the feed plate.
7.Install a drive roll on each hub assembly and lock by rotating the triangular drive roll retaining mecha- nism.
8.Install the outer wire guide by aligning it with the pins and tightening the knurled thumbscrews.
9.Close the idle arm and engage the idle roll pressure arm. Adjust the pressure appropriately.
FEEDING WIRE ELECTRODE
WARNING
•ELECTRIC SHOCK CAN KILL.
•When feeding electrode with the gun trigger, the electrode and wire drive mechanism are always "hot" to work and ground and could remain "hot" several seconds after the gun trigger is released.
COLD FEED/GAS PURGE SWITCH
1.Turn the reel or spool until the free end of the elec- trode is accessible.
2.While tightly holding the electrode, cut off the bent end and straighten the first 6" (15 cm). Cut off the first 1" (2.5 cm). If the electrode is not properly straightened, it may not feed or may jam.
3.Insert the free end through the incoming guide bushing.
4.Press the Cold Feed switch and push the electrode into the drive roll.
5.Feed the electrode through the gun.
6.Adjust the brake tension with the thumbscrew on the spindle hub, until the reel turns freely but with little or no overrun when the wire feeding stops. Do not overtighten.
