Connect a 3 phase plug with earth (minimum 40 A) to the power cable. Chief MI200T 3 phases 220 V / 50 Hz In case of bad connection or bad voltage on the electrical line, the following screen will appear : On the right hand side of the screen appears the voltage on each phase. - Page 6 Filling the cooling tank Chief Automotive Technologies recommends that you specific welding machine coolant with antifreeze and corrosion inhibitors in this cooling tank. The use of other cooling liquids, and in particular standard cooling liquids, can lead to the accumulation of solid substances inside the cooling system (due to electrolysis), this will negatively impact the cooling efficiency, and possibly cause total obstruction of the system.
