WELDSKILL 200AC/DC INVERTER
INSTALLATION, OPERATION AND SETUP
3-6
Manual 0-5207
1. Thermal Overload
This is due to the duty cycle of the power source being exceeded. Once the power source cools sufficiently
it will automatically reset and the Fault Indicator and Err 001 will go off and the power source is then
able to continue welding. During the time of cooling the power source should remain ON such that the
fan continues to operate allowing the unit to cool sufficiently. If after 30 minutes with the fan running
the Fault Indicator has not gone OFF then have an Accredited CIGWELD Service Provider check the
power source.
2. Primary Circuit Overcurrent
This is due to primary circuit component(s) malfunctioning which results in excessive primary circuit
current. Switch OFF the power source immediately to allow all components to cool down for at least
30 minutes. If after 30 minutes “Err 001” is displayed and Fault Indicator illuminates when the power
source is switched back ON turn the power source OFF and have an Accredited CIGWELD Service
Provider check the power source.
7. Process Selection Button
The process selection control is used to select the desired welding mode. Three modes are available,
GTAW (LIFT TIG), GTAW (HF TIG) and MMAW (Stick) modes.
Note that when the unit is powered off the mode selection control will automatically default to LIFT TIG mode.
This is necessary so as to prevent inadvertent arcing should an electrode holder be connected to the unit
and mistakenly be in contact with the work piece during power up.
8. Trigger Mode Control Button (HF TIG and LIFT TIG Mode only)
The trigger mode control is used to switch the functionality of the torch trigger between 2T (normal), and
4T (latch mode).
2T Normal Mode
In this mode, the torch trigger must remain depressed for the welding output to be active. Press and hold
the torch trigger to activate the power source (weld). Release the torch trigger switch to cease welding.

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 and LIFT TIG modes), the power source will remain activated until
the selected down slope time has elapsed
