PARAMETER DESCRIPTION
LIFT TIG mode of operation. A remote control device may be used for use
during LIFT TIG operation. See section 4 for the 14-Pin Remote Control
Receptacle for complete details of the remote device.
Depressing this button and illuminating the corresponding LED will enable
the Cooling Water Pressure Sensor circuitry. This circuitry operates in all
welding modes, i.e. STICK, LIFT TIG and HF TIG. If insufficient water
pressure is detected when enabled, the unit will display error code E33,
produce an audible alarm and the welding current will cease. Restoring
water pressure, or disabling the WATER COOLING circuitry by depressing
the button to extinguish the LED, will reset error code E33 and welding
WATER
current will resume.
COOLING
WARNING: Disabling the water cooling pressure circuitry is not
recommended and could cause damage to water cooled torches.
