Question about Lincoln Welding Tools

1 Answer

I am adding an outlet to service a mig welder 20 amp 230 volt. I calls for a 40 amp super lag circuit breaker. The store where I purchased the circuit breaker, wire and outlet said I could use a 50 amp and gave me 6-2 wire with copper ground. Do I need 6-2 with ground, Or is the small copper ground enough?

I have a marathon 3hp motor wired for 220 on a campbell hausfield air compressor. It has a white, black, and green wire coming out of the motor. I am using a no. 12 wire with ground. how do i wire it up to...


Hi! sims146
The Green wire from the electric motor is ground. Check the compressor motor, make sure it is wired for 220-230 Volts. If it has a white wire it could be wired 120 Volts. There should be voltage and current ratings on the motor plate. I always double check these connections. At 230 Volts this motor should be 17 Amps full Load. A 25-30 amp fuses are required to protect this motor circuit. Otherwise up to a 42.5 Amp Inverse Time Delay Breaker could be used.
The welder circuit should have 230 Volts between the Red and Black wires. The white wire is Nutral / Ground. Hopefully this is a 30 to 40 Amp circuit. The Four prong air compressor outlet, White is Neutral, Black and Red 230 Volts, Gray should be ground. Please check with Voltmeter, as some times people swap colors.

yes your ok if they say the unit doesn't need to be changed in the incomimg power from 208 up to 230 volts or vice-versa,normally they classify motors as120/208/ 230 /460 volts, instead of 120/240/480 volts,but all line voltage varies in this voltage range between 230 to 255 volts a.c. with a +10/-10 percent tolerance either way,and as long as the instructions dont say anything about changing motor connections your good to go, just look on the motor body if possible and make sure theres no wiring diagrams to change voltage,but i would say no in a package A/C like that, and as far as the current goes your good with the 20 amp tandem pole breaker,let me know if i can further assist you. thanks

Inspector is correct! In wall or conduit wiring awg will always be greater than "open air" wiring. IE: the size of wire coming from your pole ... it's smaller than from your service riser into your meter. Code allows the cord to heat up... open air will cool it down.

I have an old mastercraft 110 volt ac stick welder model 110-104 have not used it for years have lost the instruction manual plate on the machine says primary voltage is 115 and primary amperage is 26.6...


35 amp should do nicely however make sure the mains cable is of the correct size, better still, get a qualified Electricion to install it.
Usualy 30amp could be used but using 35amp gives you some reserve
