7.3 Description of the control panel operation:
- The control panel consists of buttons, LED indicators, a digital display and a knob. The control
panel is convenient for users.
- The 3-digit panel display shows parameter settings, current values and error codes E-x.
-Functions 2T; 4T and spot welding are available at operating mode of the TIG button
- ArcForce function for MMA electrode welding: automatic increase of welding current
in the case of sticking of the end of the electrode with the material being welded, particularly
useful at welding pipes.
- High-reliability TIG HF ignition
- All functional parameters are adjustable.
- TIG DC, TIG pulse, TIG AC, TIG AC pulse and MMA welding methods are available.
- Gas pre-flow time,post-flow time, initial current, upslope time, downslope time and final current
are regulated in the TIG DC and TIG AC methods.
- Gas pre-flow time, post-flow time, initial current, upslope time,
downslope time, welding current, background current, pulse frequency are adjustable at
TIG pulse and TIG AC pulse operating modes.
- The device displays error codes (see section 10) in the event of overvoltage, undervoltage or
overheating.
- An error memory function and a statistical function available Cumulative error times can be
obtained.
7.4 Saving the parameters after finishing welding.
The parameters used will be automatically saved after switching off the device (no automatic
saving will be done if no operation is performed after setting the parameters and when the
machine is switched off within 5 seconds).
When the device is switched on the next time, the parameters will be restored. When the
welding mode and the TIG button operating mode are selected again, auto-saving will be
carried out after 10 seconds.
