i got a tig welder from harbor freight 220v and i need help with the wire. ok the welder has 3 wires and the colors are green, black, and white and i am trying to hook it up to the 220v to the dryer outlet. so i bought a cord for the dryer and the cord also has 3 wires. 2 bigger ones and a littel one. so witch witch wires go to witch.
please help me

 

the two big wires will go to the white and black wire; the little wire to green that is the ground.


be very careful and make DOUBLE SURE your connections from one plug to the other are VERY SOUND; 220v + lots of amps = BIIIIIIIIIIG sparks and death

 

yea, and make sure ur breaker is off while ur wiring it up, or just dont have it connected.
good luck and what was said above should be right, the smaller wire is for ground, so whatever the welder color is for ground, hit that, the other two should be swappable.

 

I hope it worked out okay. Maybe he got zapped and fell into the washer.

If want to be sure about the connections just take a volt meter and test the connections. 2 of the possible three connections will only read around 120 volts while the other one will read around 240 volts.

 

oh man i hope u dont burn down ur house when that breaker suddenly decides to fail on u

ok black and white is the postive and green is the ground. thanks for all the help. ill make sure to have a fire extinguisher just in case lol.

 

with ac its called hot neutral and ground

the black and white are the hot and neutral (really doesn't matter polarity as its always changin) and the green weldder wire is the ground that goes to the smaller wire on the dryer. I used to work at an appliance store and we'd have to wire the welder to the type of plug in the house; its not that hard; just be very careful; a loose connection or a short can be very intersting.

 

That is strange. As far as I know the color codes, the two hot wires are supposed to be black and red. The white wire should be neutral and the green or sometimes bare wire should be ground. This is the canadian wire code however.
