Minarc T 223 ACDCOperating manual - EN>> To take pulse TIG into use, press the pulse TIG button in the control panel.>> To adjust the pulse frequency, long-press the pulse TIG button. The value ranges are listed in the followingtable.Parameter Parametervalue DescriptionPulse fre-quency, DC0.1 ... 10 Hz,step 0.110 ... 100 Hz,step 1100 ... 300 Hz,step 10Default = 1.0HzThe pulse frequency determines how many pulse cycles are created per second (Hz).(10 ... 50 Hz strains the eyes.)Pulse fre-quency, AC0.1 ... 5 Hz,step 0.1The pulse frequency determines how many pulse cycles are created per second (Hz).3.3.2 Ignition modes in TIG weldingTIG ignition modes determine the way in which the welding arc is ignited. Two ignition modes are available in TIG weld-ing: Lift TIG ignition (DC TIG only) and High Frequency (HF) ignition.Lift TIG ignition (DC TIG current mode only)In Lift TIG ignition you briefly touch the work piece with the electrode, then press the trigger and lift the electrode to asmall distance from the work piece. The Lift TIG ignition must be activated in the control panel. Also known as “Touchignition” or “Contact ignition”.High Frequency (HF) ignitionIn HF ignition, a press on the torch trigger produces a high voltage pulse that creates a spark to ignite the arc. The HFignition mode is always ON in AC TIG current mode.>> To set the HF ignition mode ON/OFF in DC TIG current mode, long-press the control panel's welding para-meters button.3.3.3 Trigger logic functionsSwitch between the 2T and 4T trigger logic by pressing the control panel's trigger logic button. The 2T and 4T triggerlogic functions are available for TIG, cleaning and polishing processes.You cannot change trigger logic during welding/cleaning/polishing.2T (default)In 2T welding, pressing the trigger ignites the arc. Releasing the trigger switches the arc off.© Kemppi 37 1922350 / 2413
