it is single phase and 3-phase. if i wanted to change plug from 4 wires to 3 wires how would i change wires on the welder it self ? thank you.
By Customer Service on August 7, 2012
Answer:The CST 280 comes with a 4 conductor power cord. If you want to run the unit on 3 phase use all 4 wires, black,white, red, and green. On 1 phase use only the black, white,and green. Do not use the red. Tape it off and isolate it. Note in some cases the odd color is not red ,but may be blue or brown. Always drop out the odd color wehn using on 1 phase

Answer:You can install a Miller HF-251D-1 High Frequency Arc Starter & Stabilizer 042388 on a Miller CST 280 Stick Welder 907251011. If your plan is to weld aluminum with is set up remember that the CST 280 produces DC weld output current and aluminum needs AC weld output so it cannot be used for aluminum

can this machine be hooked up to 220. or does something need to be changed to go from 3 phase to single phase
By Customer Service on October 23, 2013
Answer:The Miller CST 280 Stick Welder 907251011 can be run on 220 volt single phase.. All you would need to do is turn the voltage selector switch, which is under a cover on the rear of the machine , to the 220/230 volt position . The line voltage input cable is a 4 conductor cable.. When running on 220 volt single phase you would need to use only the black, white and green leads.. Drop out the red lead and insulate it properly..
