3.4.1 Welding current regulation and remote control
The welding current can be adjusted with the control knob, if panel adjustment (PANEL) is
selected.
If you want to adjust the welding current with the remote control, connect the remote control
to the machine and then select remote control with the current adjustment selector (7). The
following remote control options are available: RTC10, RTC20, R10 and R11F. The remote foot
pedal R11F can only be used with TIG welding in 2T operation mode.
3.4.2 MMA welding settings
MMA welding is selected when the indicator next to the MMA symbol is lit. If needed, press
the process selection button to select the MMA process (4). The machine automatically sets
suitable values to the ignition time, ignition pulse and arc dynamics.
3.4.3 TIG welding function
Select the TIG welding process by pressing the MMA/TIG button.
Torch switch control in 2T mode and HF arc ignition
The shielding gas starts to flow when the torch switch is pressed and the welding arc is
established automatically via HF ignition. The current starts to rise (if an upslope time is
EN
established) to the set welding current level. When you release the switch, the current starts
to decrease. After the specified downslope time, the arc is disconnected and the set post-gas
time begins.
Torch switch control in 4T mode and HF arc ignition
The shielding gas starts to flow when the torch switch is pressed. When the switch is released,
the arc is automatically established via HF ignition. The current starts to rise (if an upslope time
is established) to the set welding current level. When ready to end the welding cycle, press
and release the torch switch again. The welding current starts to drop (if a downslope time is
established) until the arc is extinguished and the set post-gas time begins.
HF or Contact ignition
The TIG arc can be established with or without an HF pulse.
If the HF indicator is not lit, the arc can be established by lightly contacting the tungsten
electrode to the work piece. Press the torch trigger and then quickly lift the contact of the
tungsten electrode from the work piece (2T function); the arc is established simultaneously
and effectively.
For HF ignition, press the HF button so that the indicator is on (item 6). Press the TIG torch
trigger and hold or release, depending on whether 2T or 4T is selected. The shielding gas flows
and the HF (High Frequency arc) ignites the welding arc.
Setting parameters
Select the welding parameters with the arrow keys (3) and adjust the parameter values with
the control knob (8). When setting the parameters, the display (9) will show the parameter
being adjusted as well as the numeric value that will be set for it. After three seconds, the
display returns to normal state and shows the welding current value.
