5.3 Welder Installation Warning! All connections shall be made with the power supply being turned off. The correct steps are: first, ground the welder reliably and ensure correct wiring without missing correction; and then connect the input power cable. 1)MMA Installation https://www.arccaptain.com... - Page 21 The welding output line cannot be coiled, as this will cause the machine to work abnormally. Select the corresponding tungsten electrode according to the current, and start welding by lift TIG or high-frequency arc starting. https://www.arccaptain.com...
