Work Cable Installation

Refer to Figure A.2.

1.Open the wire feed section door on the right side of the WELD-PAK 3200HD.

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.4. As delivered, The machine is connected for negative polarity (required for the Innershield process), con- nect the short cable attached to the connector block (1) to the negative (–) output terminal (2) and the work cable (3) to the positive (+) terminal (4).

5.For GMAW Only: Refer to Figure A..2. To wire for positive electrode polarity. the appropriate configu- ration for the GMAW (MIG) process use the provid- ed wing nut to connect the work cable’s terminal lug to the negative (–) output terminal (5) located above the Wire Feed Gearbox (6). Make sure that both wing nuts are tight.

GUN INSTALLATION

As shipped from the factory, the WELD-PAK 3200HD is ready to feed .023”-.025" (0.6 mm) solid wire. If

.030 (0.8mm) solid wire. If .030" (0.8 mm) solid wire is to be used, change the contact tip to the appropriate size.

NOTE: If .035" (0.9 mm) Innershield flux-cored wire is to be used, assemble the mig nozzle and .035” tip on to gun and reverse drive roll.

Connecting Gun Cable to the WELD-PAK

3200HD.

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 WELD-PAK 3200H case front. Make sure the con- nector 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 connector so control leads are on the under- side and tighten the Thumbscrew (8) in the con- nector block.

4.Connect the gun trigger control lead terminals to the two insulated 1/4" (6.4 mm) tab terminal con- nector bushings located below 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 WELD-PAK 3200HD, the switch must be a normally open, momentary switch. The terminals of the switch must be insu- lated from the welding circuit. Malfunction of the WELD-PAK 3200HD may result if this switch shorts to the WELD-PAK 3200HD welding output circuit or is common to any electrical circuit other than the WELD-PAK 3200HD trigger circuit.

GAS CONNECTION

When using the GMAW process, a cylinder of shield- ing gas, must be obtained. For more information about selecting gas cylinders for use with the WELD-PAK 3200HD refer to the ACCESSORIES section.
