Work Cable Installation

Refer to Figure A.2.

1.Open the wire feed section door on the right side of the SP 170-I.

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 the feedplate (6) and in front of the Wire Feed Motor.

4.For GMAW Only: Refer to Figure A.2. As deliv- ered, the machine is connected for positive elec- trode polarity. This is the appropriate configuration for the GMAW (MIG) process. To complete installa- tion, use the provided wing nut to connect the work cable’s terminal lug to the negative (–) output ter- minal (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 (required for the Innershield process), connect the short cable attached to the connector block (1) to the negative (–) output termi- nal (2) and the work cable (3) to the positive (+) ter- minal (4).

GUN INSTALLATION

As shipped from the factory, the SP 170-I gun is ready to feed .030" solid wire. If other wire is to be used, change the contact tip to the appropriate size.

Connecting Gun Cable to the SP 170-I

As shipped the gun is fitted with a liner suitable for all wire diameters from .025” - .045” (0.6mm - 1.2mm) and has an .030” (0.8mm) contact tip installed.

1.Refer to Figures A.2 and A.4. 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 (A.2-2) in the case front. The leads are to be routed up the inside of the case front, behind the gas line.

3.Insert the connector on the gun conductor cable through the Gun Cable Access Hole (A.2-2) in the SP 170-I case front. Make sure the connector is all the way in the brass connector block to obtain proper gas flow. If the gun connector will not fully insert, unscrew the thumbscrew on the connector block a few turns. Rotate the connector so control leads are on the underside and tighten the Thumbscrew on 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 (A.4). Either lead can go to either connector.

CAUTION

If the gun trigger switch being used is other than that supplied, 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 170-I may result if this switch shorts to the SP 170-I welding output cir- cuit or is common to any electrical circuit other than the SP 170-I trigger circuit.

GAS CONNECTION

When using the MIG process, a cylinder of shielding gas must be obtained. See Table B.1. Additionally a flow regulator is required. For more information, refer to the ACCESSORIES section.
