Setting AC MIX – AC TIG and DC TIG processes alternate. This function is recommended when welding different material thicknesses in aluminium. Min / Max 10% to 80%. This option is available with the advanced functions in AC.Q start and Q time (DC TIG) – Q start for a good start in low-current applications. Ideal for thin plate welding with a reliable starting arc (less chance of plate burnout). The start current can be set from 20A or higher. This function is available in the advanced functions in DC. – Q time the duration time in which the Q start should be present. Adjustable from 0.1 seconds to 60 seconds.AC WaveformSquare wave (default): Set by default in AC TIG welding. Gives a stable arc and maximises in welding and cleaning modes. The arc makes a typical noise during welding due to the rapid switch from positive to negative.– Soft square wave: A softer arc than the square wave with slightly more fluidity in the weld pool.– Trapezoidal wave: Low heat input ideal for thin materials that use a higher AC frequency.– Sine wave: Soft, smooth arc with a lower noise level. Heat input is between square wave and trapezoidal wave with a lower welding speed.Complete the XTT212Di with the XTS908 water cooler. – Capacity: 5 litres – Max. Flow water cooler: ≥2 litres/min – Weight water cooler empty: 5.5 kg – The water cooler can also be fitted to the XTT212Di at a later date (plug & work system).
