EN3.4.1 Welding current regulation and remote controlThe welding current can be adjusted with the control knob, if panel adjustment (PANEL) isselected.If you want to adjust the welding current with the remote control, connect the remote controlto the machine and then select remote control with the current adjustment selector (7). Thefollowing remote control options are available: RTC10, RTC20, R10 and R11F. The remote footpedal R11F can only be used with TIG welding in 2T operation mode.3.4.2 MMA welding settingsMMA welding is selected when the indicator next to the MMA symbol is lit. If needed, pressthe process selection button to select the MMA process (4). The machine automatically setssuitable values to the ignition time, ignition pulse and arc dynamics.3.4.3 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 the welding arc isestablished automatically via HF ignition. The current starts to rise (if an upslope time isestablished) to the set welding current level. When you release the switch, the current startsto decrease. After the specified downslope time, the arc is disconnected and the set post-gastime begins.Torch switch control in 4T mode and HF arc ignitionThe 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 timeis established) to the set welding current level. When ready to end the welding cycle, pressand release the torch 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 contacting the tungstenelectrode to the work piece. Press the torch trigger and then quickly lift the contact of thetungsten electrode from the work piece (2T function); the arc is established simultaneouslyand effectively.For HF ignition, press the HF button so that the indicator is on (item 6). Press the TIG torchtrigger and hold or release, depending on whether 2T or 4T is selected. The shielding gas flowsand the HF (High Frequency arc) ignites the welding arc.Setting parametersSelect the welding parameters with the arrow keys (3) and adjust the parameter values withthe control knob (8). When setting the parameters, the display (9) will show the parameterbeing adjusted as well as the numeric value that will be set for it. After three seconds, thedisplay returns to normal state and shows the welding current value.MinarcTig Evo 200, 200MLP10
