WARNING

ELECTRIC SHOCK can kill.

•Keep the electrode holder, TIG torch and cable insulation in good condition and in place.

•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® V205- T AC/DC™ “off” before connecting or discon- necting output cables or other equipment.

This unit does not include a TIG torch, but one may be purchased separately. The accessories section of this manual lists a number of Lincoln Electric TIG torches, and TIG Torch Starter Packs that are recommended for use with this machine; 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.

OUTPUT AND GAS CONNECTION FOR TIG WELDING (FIGURE A.1)

The TIG Torch Twist-Mate and work cable Twist-Mate Connectors are supplied with the welder. To connect the cables, turn the Power Switch “OFF”. Connect the torch cable Twist-Mate plug into the DC(-) Electrode/Gas Output Receptacle on the front of the welder and turn it clockwise until snug,(Do not Overtighten). This is a quick connect terminal and also provides the gas connection for the shielding gas to the torch.

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 terminal. Insert the connector with the key lining up with the key- way, and rotate clockwise; until the connection is snug. Do not over tighten.

WARNING

To avoid receiving a high frequency shock, keep the TIG torch and cable insulation in good condi- tion.

WORK CABLE CONNECTION

Next, connect the work cable to the “+” output terminal in the same way. To minimize high frequency interfer- ence, refer to Machine Grounding and High Frequency Interference Protection section of this manual for the proper procedure on grounding the work clamp and work piece.
