FEEDING ELECTRODE AND BRAKE ADJUSTMENT
1.Turn the reel or spool until the free end of the electrode is accessible.
2.While tightly holding the electrode, cut off the bent end and straighten the first 6 in. (150 mm). Cut off the first 1 in. (25 mm). (If the electrode is not properly straightened, it may not feed or may jam causing a “birdnest”.)
3.Insert the free end through the incoming guide.
4.Press the Cold Feed Switch while pushing the electrode into the incoming wire guide.
WARNING
If feeding with the Gun Trigger, the electrode and wire drive may be electrically “HOT”.
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 wire feeding is stopped. Do not overtighten.
DRIVE ROLL KIT INSTALLATION (KP1505-[])
1.Turn off welding power source.
2.Pull open pressure door to expose rolls and wire guides.
3.Remove outer wire guide by turning knurled thumb screws counterclockwise to unscrew them from Feedplate.
4.Remove the drive rolls, if any are installed, by pulling straight off the shaft. Remove the inner guide.
5.Insert the inner wire guide, groove side out, over the two locating pins in the feedplate.
6.Install each drive roll by pushing over the shaft until it butts up against the locating shoulder on the drive roll shaft. (Do not exceed maximum wire size rating of the wire drive).
7.Install the outer wire guide by sliding over the locating pins and tightening in place.
8.Engage the upper drive rolls if they are in the “open” position and close pressure door.
To set drive roll pressure, see Drive Roll Pressure
Setting.
DRIVE ROLL PRESSURE
SETTING
The Power Feed 10 pressure is factory
The optimum drive roll pressure varies with type of wire, surface condition, lubrication, and hardness. Too much pressure could cause “birdnesting”, but too little pressure could cause wire feed slippage with load and/or acceleration. The optimum drive roll set- ting can be determined as follows:
1.Press end of gun against a solid object that is electrically isolated from the welder output and press the gun trigger for several seconds.
2.If the wire “birdnests”, jams, or breaks at the drive roll, the drive roll pressure is too great. Back the pressure setting out one turn, run new wire through the gun, and repeat above steps.
3.If the only result is drive roll slippage, disengage the gun, pull the gun cable forward about 6 in. (150 mm). There should be a slight waviness in the exposed wire. If there is no waviness, the pressure is too low. Increase the pressure setting one turn, reconnect the gun, tighten locking clamp and repeat the above steps.
PROCEDURE FOR SETTING ANGLE OF FEEDPLATE
1.Loosen the clamping collar screw using a 3/16 in. Allen wrench. The clamping collar screw is accessed from the bottom of the feedplate. It is the screw which is perpendicular to the feeding direction.
2.Rotate feedplate to the desired angle and tighten clamping collar screw.
