Work Cable Installation
Refer to Figure A.2.
1.Open the wire feed section door on the right side of the PRO 100.
2.Pass the end of the work cable that has the termi- nal lug with the smaller hole through the Work Cable Access Hole (1) in the case front.
3.Route the cable under and around the back of the Wire Feed Gearbox (6).
4.For Innershield Only: Refer to Figure A.2. As delivered, the PRO 100 is connected for negative electrode polarity. This is the appropriate configu- ration for the Innershield process. To complete installation, use the provided wing nut to connect the work cable’s terminal lug to the positive (+) out- put terminal (5) located above the Wire Feed Gear- box (6). Make sure that both wing nuts are tight.
5.For GMAW Only: Refer to Figure A.4. To wire for positive polarity (required for the MIG process), connect the short cable attached to the connector block (1) to the positive (+) output terminal (4) and the work cable (3) to the negative

GUN INSTALLATION
As shipped from the factory, the PRO 100 gun is ready to feed 0.035” (0,9 mm) wire. If .023"
Connecting Gun Cable to the PRO 100
1.Refer to Figure A.2. Unplug the machine or turn power switch to the OFF “O” position.
2.Pass the insulated terminals of the gun trigger con- trol leads, one at a time, through the Gun Cable and Control Lead Access Slot (2) in the case front. The leads are to be routed under the Wire Feed Gearbox (6) and through the Cable Hanger (7) on the inner panel.
3.Insert the connector on the gun conductor cable through the Gun Cable Access Hole (2) in the PRO 100 case front. Make sure the connector is all the way in the brass connector block. Unscrew thumbscrew on the connector block a few turns if gun connector will not insert fully. Rotate the con- nector so control leads are on the underside and tighten the Thumbscrew (8) in the connector block.
4.Connect the gun trigger control lead terminals to the two insulated 1/4" (6,4 mm) tab terminal con- nector bushings located above the “Gun Trigger Connection” decal in the wire feed section (4). Either lead can go to either connector. Form the leads so that they are as close as possible to the inside panel.
CAUTION
If the gun trigger switch being used is other than that supplied with the PRO 100, the switch must be a normally open, momentary switch. The termi- nals of the switch must be insulated from the welding circuit. Malfunction of the PRO 100 may result if this switch shorts to the PRO 100 welding output circuit or is common to any electrical cir- cuit other than the PRO 100 trigger circuit.
