Thanks in advance. My garage is wired with a 220v 20amp outlet. My Lincoln has, what I believe to be a 50 amp plug. Is it OK to cut that off and just wire a 220 v male outlet to fit?
Reply:If plug fits on the outlet, your ok.That machine won't need over 20amps.The 50 amp on the plug is just the style it is.People run anywhere from 20 to 100ps thru those plug.Again,Do you have a picture of the plug and outlet ?
Reply:No, 20 amps is not enough. Run a 6/3 or 8/3 50 amp circuit for the welder.

Reply:Thanks MinnesotaDave. But not sure what that all means.
Reply:Ok,I'm messed up.I'm not sure about those small plugs.Someone else knows more about them I'm sure.I don't even know if you'll be able to fit the welders power cord wires on that new plug. The wire may be to big.Carry on....
Reply:That plug will work up to a certain point, then trip the breaker.If you are going to use it much and want to cut down on the frustration of having to reset you breaker, install a 40 amp circuit with 8 gauge wire. Better yet, install a 50 amp breaker with 6 gauge wire so you will have a place to plug in a buzz box when you get one.GravelThe difference between theory and practice is that in theory there is no difference.

Reply:I researched this when I was getting my first welder. I had 15 amp circuits in my garage, and the welder would pull up to 27 amps.In short; you are OK using that circuit for that welder. Using that plug is fine.The long answer; The code that governs electrical wiring has some interesting things to say about circuits for welding. I'll give a bare bones summary. The first point to know is that a circuit breaker is to protect the wiring from over heating. Insulation on overheated wires breaks down and causes shorts and fires. Wire can be overloaded a little for a short time, so a 20 amp break will not pop under 50% overload for several minutes.The second point is that welders considered an "intermittent load" by the electrical code. This is important because welding usually involves a lot of starts and stops. Your welder is rated for 22 amps draw at 175 amp output. Note that the chart says but is only to be used at 130 amp output for 3 minutes out of every 10. That could be 3 welds of 1 minute each, or 6 welds of 20 seconds each or 1 weld of 3 minutes. This is the "duty cycle" of 30%. At full 170 amp output your duty cycle is likely to be 10%. Remember, the wire cools down when the welder is not being used.The third point is that thinner wire will lose more energy to heating. The longer the wire is, the thicker it has to be to avoid losing too much power. If possible, make sure that the 220 wiring is of the proper size for the distance that it is from the circuit breaker. If you use an extension cord, use a 20 or 30 amp cord if possible.The fourth point is that your welder must be the only device on the circuit. The duty cycle allows the wire and circuit breaker to cool between welds. When lights are on, they have a 100% duty cycle so the wire does not cool down as much. If you have 500 watts of lights on the same circuit, then your welder may overload the breaker or overheat the wires.Last; When you are using the welder at LESS than 100% output (say... 90 amps) it will draw a lot less power from the outlet. Read the charts in the manual to find out what the duty cycle is at the lower amp settings.Hope that helps.Dan
Reply:Thanks all. That is the sole outlet on that circuit. I did put on the new plug and did my first few welds. All went fine. Well accept that I don't know how to weld yet.
Reply:Do you own the house? what was plugged into that outlet before ,what gauge is the wire, is the panel box in garage or basement where you can add conduit and pulled #6 or #8 wire with a 50 amp breaker and outlet. you don't want to loose your home because you over heated a #12/#14 romex wire .gxbxc
Reply:As GXBXC said, it's a good idea to open the breaker panel or pull the socket and check to ensure that your 20 amp circuit is using wire that is 12 ga or bigger. Bigger would be 10 ga.Some people make the mistake of replacing a 15 amp outlet with a 20 amp outlet without upgrading the wire. If it was there when you moved in, there is no telling if it was done right. Even electricians sometimes use the wrong wire, so it does not hurt to check.Dan |
