Work Cable Installation
Refer to Figure A.2.
1.Open the wire feed section door on the right side of the Handymig 170i.
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 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
(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

GUN INSTALLATION
As shipped from the factory, the Handymig 170i gun is ready to feed .023"
NOTE: If .035" or .045" (0.9 mm or 1.2 mm) Innershield
Connecting Gun Cable to the Handymig 170i.
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 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 (2) in the Handymig 170i case front. Make sure the connec- tor 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 con- nector 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 (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 Handymig 170i may result if this switch shorts to the Handymig 170i welding output circuit or is common to any electrical cir- cuit other than the Handymig 170i trigger circuit.
GAS CONNECTION
The Handymig 170i is supplied with a mixed gas Regulator and a 3m gas hose. A cylinder of an appro- priate shielding gas must be obtained from your gas distributor.
