3.Route the cable under and around the back of the Wire Feed Gearbox (6).

4.For GMAW Only: Refer to Figure A.2. As deliv- ered, the SP-135 PLUS is wired for positive polari- ty. This is the appropriate configuration for the Gas Metal Arc Welding (GMAW) process. To complete installation, use the provided 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.

5.For Innershield Only: Refer to Figure A.4. To wire for negative polarity, connect 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).

GUN INSTALLATION

As shipped from the factory, the SP-135 PLUS gun is ready to feed .023 - .025” (0,6 mm) wire. If .030-.035” (0.8-0.9 mm) wire is to be used, change the contact tip to the appropriate size. Refer to the MAINTENANCE section for contact tip installation details.

NOTE: If .035” Innershield Flux-cored wire is to be used, see the Accessories section for the Innershield Welding Kit.

Connecting Gun Cable to the SP-135

PLUS

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 SP- 135 PLUS case front. Make sure the connector is all the way in the metal connector block to obtain proper gas flow. Rotate the connector 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 connector 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 SP-135 PLUS, the switch must be a normally open, momentary switch. The terminals of the switch must be insulated from the welding circuit. Malfunction of the SP-135 PLUS will result if this switch shorts to the SP-135 PLUS welding output circuit or is common to any electri- cal circuit other than the SP-135 PLUS trigger circuit.

GAS CONNECTION

Refer to Figure A.5

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 SP-135 PLUS, refer to the ACCESSORIES section.
