Lincoln Electric IM528-B Operation on Other Lincoln Power Sources, Lincoln Power Source Settings

OPERATION

OPERATION ON OTHER LINCOLN POWER SOURCES

The table (Table 13) lists the recommended switch and control settings for the TIG Module when used with various Lincoln power sources.

Operate the power source in accordance with its Manual.

Note that AC power sources must be derated approximately 50% when used for AC TIG welding. This is due to the special nature of the TIG welding arc. Input currents will also be higher when AC TIG welding. Be sure the power source is properly fused to handle this situation.

If your power source has remote control capability,

refer to the second half of the diagram Figure 9 which covers the proper use of the TIG Module Current Control with Hand and Foot Amptrols.

Once the TIG Module and the power source are properly set up, TIG welding is very easy. Position the torch in place, lower your helmet, and press the Arc Start Switch or Amptrol. The power source contactor (or the optional TIG Module contactor) will close, gas will flow for a one-half second preflow time, and the high frequency will come on. The arc should strike and welding should begin. At the end of the weld, simply release the Arc Start Switch or Amptrol, and the contactor will open, shutting off the arc. The Afterflow time will begin, cooling the torch, protecting the weld and the tungsten. If another weld is started during the Afterflow time, there will be no preflow time delay. The contactor will close immediately when the Arc Start Switch or Amptrol is pressed.
