Connection of TIG Module (K930-1) to the Ranger 8

The TIG Module is an accessory that provides high frequency and shielding gas control for AC and DC GTAW (TIG) welding. See IM528 supplied with the TIG Module for installation instructions.

Note: The TIG Module does not require the use of a high frequency bypass capacitor. If any other high frequency accessory is used with the Ranger 8, a bypass capacitor (Order Kit T12246) must be installed in the Ranger 8.
