1. Open the case side door.

2. Slide the connector end of the gun and cable through the hole of the machine front and into the gun connector bushing on the wire drive.

3. Make sure the gun connector end is seated fully into the wire drive and tighten the thumbscrew to secure the gun.

4. Plug the gun trigger lead connector into the 4 pin gun trigger receptacle on the machine front.

5. Wire Drive Polarity. MIG welding requires Positive

(+) polarity. Connect the short power cable from the wire drive to the positive (+) output terminal and tighten the thumbscrew.

6. Work Lead Connection. Slide the lugged end of the work cable through the hole in the machine front and place on the negative (-) output terminal and tighten thumbscrew.

1. Locate the green labeled 4"(102mm) diameter spool of .025”(0.6mm) L-56 solid MIG wire and place onto wire spool spindle. Orient the spool so that the wire feeds off the top of the spool.

2. Secure spool in place by tightening the wing nut against the against the spacer that holds the wire spool on the spindle.

3. Open the top drive roll pressure arm by rotating the tension adjustor arm down and pivoting the idle roll pressure arm up.

4. Remove the outer wire guide.

4a. Slide gun out of drive slightly.

5. Remove the lower drive roll and inner wire guide.

6. Install the .025”-.035”(0.6mm-0.9mm) inner wire guide.

7. Install the .025”(0.6mm) smooth grooved lower drive roll.

8. Carefully unwind and straighten the first six inches of welding wire from the spool. Do not let the end of the wire go to prevent the wire from unspooling.
