WELDSKILL 200AC/DC INVERTER
Manual 0-5207 3-7 INSTALLATION, OPERATION AND SETUP
9. Wave Balance / Arc Force Indicator
This indicator light will illuminate when programming Wave Balance (AC HF TIG mode only) or Arc Force
(STICK mode only).
10. Forward Programming Button
Pressing this button will advance to the next step in the programming sequence.
11. Multifunction Control
The multifunction control knob is used to adjust welding current.
It is also used to adjust parameters when in programming mode.
12. Back Programming Button
Pressing this button will go back to the previous step in the programming sequence.
13. AC frequency Indicator
This indicator light will illuminate when programming AC Frequency (AC HF TIG mode only).
14. Purge Button
Press and hold the PURGE button to purge the gas line in LIFT TIG and HF TIG modes. To PURGE the
shielding gas line in LIFT TIG and HF TIG modes press the PURGE button and release. The indicator will
illuminate and shielding gas will purge for a preset period of 15 seconds. (This cannot be adjusted). To stop
shielding gas from purging within this time press the PURGE button and release and the purge indicator
will extinguish and shielding gas will cease.
15 Pulse Button
Press the PULSE button to toggle Pulse On and OFF in LIFT TIG and HF TIG modes
16. Programming Parameter Indicators
These indicator lights will illuminate when programming.
17. Mode Button
Press the MODE button to toggle AC and DC output in all Process modes
18. Digital Ammeter
The digital amperage meter is used to display both the pre-set current and actual output current of the
power source.
At times of non-welding, the amperage meter will display a pre-set (preview) amperage value. This value
can be adjusted by varying the multifunction control when the Programming Parameter Indicator light
shows BASE CURRENT.
When welding, the amperage meter will display actual welding current.
Should a remote device be connected the maximum setting of the power source will be determined by the
respective front panel control, irrespective of the remote control device setting. As an example, if the output
current on the power source front panel is set to 50% and the remote control device is set to 100%, the
maximum achievable output from the unit will be 50%. Should 100% output be required, the respective
power source front panel control must be set to 100%, in which case the remote device will then be able
to control between 0-100% output.
