REAR CONTROL PANEL

1.Power Switch: Controls the input power to the machine. Make sure the machine is properly con- nected to the input supply before turning the machine on.(See Figure B.1)

2.Fan: The cooling fan will turn ON when the machine is turned ON and it will continue to run whenever the output of the machine is ON. If the output of the machine is OFF for more than five min- utes, the fan will turn OFF. This reduces the amount of dirt that is deposited inside the machine and reduces power consumption.(See Figure B.1)

Refer to the Output LED section below for more information about conditions when the output of the machine is ON.

3.Gas Inlet: Connector for the TIG shielding gas. The gas source must have a pressure regulator and flow gage installed.(See Figure B.1)

CONTROLS AND SETTINGS (See Figure B.2)

4.Mode Switch: This switch changes the welding modes of the machine. The V160-T has three weld- ing modes: Stick (SMAW), Lift TIG (GTAW) and HF TIG (GTAW).

When the mode switch is in the Stick position, the fol- lowing welding features are enabled:

•Hot Start: This is a temporary increase in the output current during the start of the stick welding process. This helps ignite the arc quickly and reliably.

•Arc Force: This is a temporary increase in the out- put current during normal stick welding. This tem- porary increase in output current is used to clear intermittent connections between the electrode and the weld puddle that occur during normal stick welding.

•Anti-Sticking: This is a function which decreases the output current of the machine to a low level when the operator makes an error and sticks the electrode to the work piece. This decrease in cur- rent allows the operator to remove the electrode from the electrode holder without creating large sparks which can damage the electrode holder.
