If you only have 3 wires you don't have the fourth wire for 120V. Since this is a 240V only device it doesn't need it. Black and white are your hots and green is ground.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What are the wires on a Lincoln ac 225 welder there are 2 black and 1 green?

Check the nameplate on the welder, if the voltage that runs the welder is 240 volts then the two black wires connect to a 240 volt supply and the green wire connects to the ground of the supply.


If you have a spa that is 240V with 4 wires can you hook an extension cord from a 240V welder to it to see if it works if the cord only has three wires?

Well, maybe. What is the current rating on the spa circuit? What is the current rating on the welder? If the welder is larger than the outlet, then no. It must be the other way around. If the current ratings are OK, then yes. Your welder doesn't need 110V so it doesn't connext to neutral. Connect the hot leads to hot and ground to ground.


How big of a generator do you need to drive a 200 amp welder?

When you refer to a 200 amp welder you are talking about the output side of the welder. What you have to do is find out what the input voltage and current of the welder is to calculate the size of a generator needed to operate the welder.


How do I wire a single phase 120 amp 230 volt flux and mig welder to a 200 amp panel?

It is very likely that the 120A current you quote is the output current. Check your Welder Box and look at the input current. It is likely around 30 Amps. To wire a 30A circuit you will need 10 gauge wire and it is likely 3 conductots + ground. You will need a 230V Breaker. Connect the black and red wires from the 10 gauge cable to the breaker, white wire to neutral and ground to ground.


What size circuit breaker is needed for a 190 amp welder?

The size of the circuit breaker and the wire that will feed the welder is based on the amperage that is needed by the welder. The voltage only explains what the insulation factor of the wire should be.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

What does welder do?

Welder as in the person: A welder joins metal together using Oxy-fuel or more commonly Arc processes. Welder as in the Machine: A welder converts electricity from your home/workplace and turns it into suitable voltage and amperage for welding operations. That is to melt the base metal and add filler metal (electrode) In the case of gouging the arc is transferred between the carbon electrode, melts the base metal and a stream of compressed air carries the molten puddle away. A Welding machine may also be a fuel driven machine often used on job sites away from electrical connections.

Is TIG Welder is also considered as Co2 welder?

No , although Co2 may be used , along with other gasses , a welder using this process is not considered a Co2 welder . TIG stands for tungsten Inert Gas , so the welder is considered / called a TIG Welder.
