Plug the welder into the proper power supply receptacle. Flux Core Wire Installation Welding power may be applied to the output terminals, feed roll, work clamp, gun cable connection and welding wire even when the the gun switch is not activated. Do not touch these parts when the welding machine is on. Note: Before installing welding wire, be sure that the diameter of the welding wire matches the groove in the drive roller on the wire feed mechanism and that the wire size matches the contact tip in the end of the gun (see Figure 5). Any mismatch could cause the wire to slip, bind or weld poorly. 1. Verify the unit is off and lift the panel on the welder to expose the wire feed mechanism. 2. Remove the spool quick lock by pushing in and rotating 1/4 turn counterclockwise. The knob, spring, and spool spacer can now be removed. 3. Loosen the wire feed tensioning screw on the drive mechanism. This allows initial feeding of the wire into the gun liner by hand. 4. Install the wire spool onto the spindle so that the wire can come off !

Do not cut the wire loose yet. Install the spool spacer, spring, and quick lock knob by pushing in and turning the knob 1/4 rotation clockwise. 5. Hold the wire and cut the wire end from the spool. Do not allow the wire to unravel. Be sure that the end of the wire is straight and free of burrs. 6. Feed the wire through the wire feed guide tube, over the groove in the drive roll and into the gun liner. Tighten the wire feed tensioning screw so that it is snug. Do not over tighten. Install the outer welder panel. 7. Remove the nozzle by turning counter-clockwise. Then unscrew the contact tip from the end of the welding torch (See Figure 5). Plug the welder into the proper power supply receptacle. 8. Turn on the welder and set the wire speed rate to Maximum. Activate the gun switch until the wire feeds out past the torch end. Turn welder off. 9. Carefully slip the contact tip over the wire and screw it into the torch end. Install the nozzle by turning clockwise. (See Fig. 5). Cut the wire off approximately 1/4 inch from the end of the nozzle.

Cut retainer stiffeners and detachable handle away from shield. Trim the excess plastic to remove sharp edges. 2. Insert filter lens. 3. Attach the stiffeners over the pins on the lens retainers (See Figure 9). 4. To attach the handle, place shield on a flat surface and press handle into place (See Figure 10). Figure 10 NOTE: If you have never welded before or have little experience, a full face helmet is recommended. Both hands are needed to stabilize and control the angle and arc length of the torch.

Remove the lens retainer from the helmet. 2. Place the clear lens into the helmet first, then place the shaded lens into the helmet. The clear lens should be on the outside. Its purpose is the protect the shaded lens from sparks and spatter. Secure the two lenses by snapping the lens retainer in place. 3. Position the adjustment arm on the right side of the helmet. Place the small pin on the arm into one of the small holes in the helmet. This adjustment controls the fit of the helmet when it is lowered, and can be easily repositioned if necessary. 4. Position the headgear inside the helmet. Assemble the helmet by inserting the stud screw through the headgear and helmet (and adjustment arm on the right side) into the tension nut as shown. Do not tighten the tension nut completely. 5. Trial fit the welding helmet. Adjust headgear ratchet band to a comfortable position and lower the helmet. If the helmet is too far or too close to the face, use a different hole for the adjustment arm. Adjust t...
