EN132.6.1 Welding current regulation and remote controlThe welding current can be adjusted steplessly with the control knob, ifpanel adjustment (PANEL) is selected.If you want to adjust the welding current with the remote control, connectthe remote control to the machine and then select remote control with thecurrent adjustment selector (7). The following remote control options areavailable: RTC10, RTC20, R10 and R11F. The remote foot pedal R11F can onlybe used with TIG welding in 2T operation mode.2.6.2 mma welding settingsMMA 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, ignitionpulse and arc dynamics.2.6.3 tig welding functionSelect the TIG welding process by pressing the MMA/TIG button.torch switch control in 2t mode and hf arc ignitionThe shielding gas starts to flow when the torch switch is pressed and thewelding arc is established automatically via HF ignition. The current starts torise (if an upslope time is established) to the set welding current level. Whenyou release the switch, the current starts to decrease. After the specifieddownslope time, the arc is disconnected and the set post-gas time begins.torch switch control in 4t mode and hf arc ignitionThe shielding gas starts to flow when the torch switch is pressed. When theswitch is released, the arc is automatically established via HF ignition. Thecurrent starts to rise (if an upslope time is established) to the set weldingcurrent level. When ready to end the welding cycle, press and release thetorch switch again. The welding current starts to drop (if a downslope time isestablished) until the arc is extinguished and the set post-gas time begins.hf or Contact ignitionThe 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 contactingthe tungsten electrode to the work piece. Press the torch trigger and thenquickly lift the contact of the tungsten electrode from the work piece (2Tfunction); the arc is established simultaneously and effectively.For HF ignition, press the HF button so that the indicator is on (item 6). Pressthe TIG torch trigger and hold or release, depending on whether 2T or 4T isselected. The shielding gas flows and the HF (High Frequency arc) ignites thewelding arc.13© Kemppi Oy / 1339
