OPERATING STEPS

WELDING IN TIG MODE

1.Connect the TIG torch and cable Twist-Mate™ quick connect plug to the Electrode/Gas output recepta- cle. This receptacle also contains an integral gas connection for the torch. Connect the work clamp to the work piece.

2.Set the TIG/STICK switch to “TIG”.

3.Set the Polarity Switch to DC- for welding steel or stainless steel; or to AC for welding aluminum.

4.Connect the Foot Amptrol to the Remote Control Connector.

5.Turn on the cylinder gas valve and adjust the flow regulator to obtain desired flow.

6.Turn the power switch to “ON”. NOTE: There will be a 15 second gas flow when the power is turned on.

7.Preset the Output Control on the control panel to the maximum desired amps, as read on the digital meter.

8.Depress the Foot Amptrol to energize the torch and establish an an arc with the work piece. The digital meter reads the actual amps while welding.

NOTE: When the TIG/STICK switch is set to “TIG”, depressing the remote control will start a 0.5 second gas pre-flow before energizing the TIG torch. When the remote control is released the TIG torch is de-energized and gas flow will con- tinue for the time set by the Post Flow Time control. When the polarity switch is set to DC, the TIG Arc Starter will turn on and off auto- matically to start and stabilize the arc. In AC the TIG Arc Starter will turn on with the output and remain on continuously until the remote control is released.

PULSE TIG CONTROL

Use this knob to set the frequency or the number of pulses per second(pps), from 0.1pps to 20pps.

This setting adjusts heat output and bead shape for travel speed. Thinner plate that is welded with faster travel speed will require higher frequency than thick- er plate with slower travel speed. 2-3pps is a typical starting point.
