THE K930-2 TIG MODULE

•Set the WELD MODE switch to the “Touch Start Tig 20-250 Setting”.

•Set the IDLER switch to the “AUTO” position.

•Set the WELDING TERMINALS switch to the “Remotely Controlled” position. This will keep the solid state contactor open and provide a “cold” electrode until the triggering device (Amptrol or Arc Start Switch) is pressed.
