1.Verify the unit is off and lift the panel on the welder to expose the wire feed mechanism.

2.Loosen the wire feed tensioning screw on the drive mechanism. This allows initial feeding of the wire into the gun liner by hand.

3.Install the wire spool onto the spindle so that the wire can come off the spool on the end closest to the wire feed guide tube. Do not cut the wire loose yet.

4.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.

5.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. Close the wire feed panel.

7.Turn on the welder and activate the gun switch until the wire feeds out past the torch end. Turn welder off.

8.Carefully slip the contact tip over the wire and screw it into the torch end. Install the nozzle by turning clockwise. (See Figure 5). Cut the wire off approximately 1/4 inch from the end of the nozzle.

Assembly - WF2000

All welding accessories for the welder are inside the wire feed compartment. Lift and remove wire feed cover to find handle, workclamp, etc.

Handle Assembly

1.Slide handle into plastic ends as shown (Fig. 6).

Figure 6 - Handle Assembly

2.Place handle assembly on welder aligning two holes in plastic ends with threaded holes in welder housing.

3.Fasten screws through handle ends and into cabinet.

WORK CLAMP

1.Loosen hex bolt on work clamp.

2.Insert cord (labeled work on the front panel of the welder) through clamp handle and slide bare wire under the clamp block. Tighten hex bolt making sure bare wire is clamped securely (Fig. 7).

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.
