Lincoln Electric V160-S manual Output and GAS Connection for TIG Welding Figure A.1

A-4 INSTALLATION A-4

The following Lincoln engine drives meet these condi- tions when run in the high idle mode:

•Ranger 250,305

•Commander 300, 400, & 500

Many engine drives do not meet these conditions (eg Miller Bobcats, etc). Operation of the Invertec V160-S is not recommended on engine drives not conforming to these conditions. Such combinations may overvolt- age the Invertec V160-S power source.

OUTPUT CONNECTIONS

WARNING

ELECTRIC SHOCK can kill.

•Keep the electrode holder and cable insulation in good condition.

•Do not touch electrically live parts or electrode with skin or wet cloth- ing.

•Insulate yourself from work and ground.

•Turn the input line Switch on the Invertec V160- S “off” before connecting or disconnecting out- put cables or other equipment.

First determine the proper electrode polarity for the electrode to be used. Consult the electrode data for this information. Then connect the output cables to the output terminals corresponding to this polarity. For instance, for DC(+) welding, connect the electrode cable (which is connected to the electrode holder) to the “+” output terminal and the work cable (which is connected to the work clamp) to the “-” output termi- nal. Insert the connector with the key lining up with the key way, and rotate approximately 1/4 turn clock- wise; until the connection is snug. Do not over tighten.

This unit does not include a TIG torch, but one may be purchased separately. The Lincoln (K1781-7 PTA-9FV, K1782-11 PTA-17FV) and (K1782-6, K1782-8 PTA- 17V) are recommended for use with this machine for this purpose; however, any similar TIG torch can be used. To attach the Twist-Mate Plug to a Lincoln Torch, slide the rubber boot onto the torch cable (enlarge the boot opening if necessary), screw the fit- ting on the torch cable into the brass connector snugly and slide the boot back over the brass connector.
