Minarc T 223 ACDCOperating manual - EN3.3 Additional guidance to functions and featuresThis section summarizes some of the Minarc T 223 ACDC functions and features and how to use them.3.3.1 TIG processes and current modesAC TIGAC (alternating current) TIG is a TIG current mode where the polarity of the electrode alternates rapidly between positiveand negative. Used especially in aluminum welding.>> To select the AC TIG current mode, press the control panel's current mode button in the TIG operation mode.>> To adjust the AC balance, long-press the current mode button in the AC TIG current mode.>> To adjust the AC frequency, press the current mode button or the control knob button when the AC balanceadjustment is active.Parameter Parametervalue DescriptionAC+ / AC-balance-60 ... 0 %,step 1,default = -25%Adjust the positive and negative current cycles in AC TIG welding. Low percentage means that, onaverage, the welding current is more on the negative side, and high percentage that, on average,the welding current is more on the positive side.AC fre-quency30 ... 200 Hz,step 1 (up to100 Hz),step 10 (over100 Hz)Default = 60HzAdjusts the frequency of the alternating current in AC TIG welding.DC- TIGDC- (direct current, negative polarity) TIG is a TIG current mode where the polarity of the electrode is negative through-out the welding process. Negative polarity allows high penetration.>> To select the DC- TIG current mode, press the control panel's current mode button.Pulse TIGPulse TIG is a welding process where the current is pulsed between the base current and the pulse current. Pulse TIG isused for optimizing arc characteristics.The user can adjust the pulse frequency, other parameters are defined by the active welding program (separately for DCand AC).© Kemppi 36 1922350 / 2413
