OPERATION 4-4 Manual 0-5555
4T Latch Mode
This mode of welding is mainly used for long welding runs to reduce operator fatigue. In this mode
the operator can press and release the torch trigger and the output will remain active. To deactivate the
power source, the trigger switch must again be depressed and realised, thus eliminating the need for the
operator to hold the torch trigger.
Note that when operating in GTAW (HF TIG mode), the power source will remain activated until the
selected down slope time has elapsed

SPOT Mode
Spot welding is used to weld two thin plates together at a desired location by melting the top and
bottom plates together to form a nugget between them. The weld time is set by adjusting the Spot
Time duration to the desired time. To select and set Spot time first select Spot Mode on the Trigger
and Spot Mode Control Button then either using the Multifunction Control Knob (11) or Back button
increment until the Spot Time
indicator is selected then use the Multifunction Control Knob to
set the desired Spot Time duration in seconds. Range is 0.5 to 10 seconds.
9. Gas Purge Button
Press and hold the PURGE button to purge the gas line in TIG modes. To PURGE the shielding gas line in
HF TIG mode press the PURGE button. The indicator will illuminate. To stop shielding gas from purging
release the Gas Purge button and the purge indicator will extinguish and shielding gas will cease.
10. Arc Force Indicator
This indicator light will illuminate when programming Arc Force (STICK mode only). Refer to Section
6.02 in the Programming Mode for further detail.
11. Multifunction Control Knob
The multifunction control knob is used to adjust welding current.
It is also used to adjust parameters when in programming mode.
12. AC Hz (Frequency) Indicator (AC TIG Modes only)
This indicator light will illuminate when programming AC Frequency (AC TIG modes only). Refer to Section
5.03 in the Programming Mode for further detail.
