We just ran across 65 feet of Essex Royal 10-4 SOW 600V cable for free(the best price). This should work for what I am doing would'nt you think? My connects are three wire but, I could just cut back the fourth correct?
Thanks,
Mario and Tyler

That will work fine. Good buy on the wire

Thanks to all once again

Dad! is that you???
Gee imagine, two electrodes and we're both named bull. shheet!

anywaz, 10 is rated in ye ol happy code book at 35-40 amps depending on your insulation. although it should be fused at no more than a 30 amp ckt bkr. Dont know the needs of your welder but it will say on the nameplate. yes you can just cut off or not use the neutral. happy welding. my welder says it uses 53 amps on the primary side. (a stick welder) have never had any trouble with it so far on a 50A breaker but ya aint spozed to do that!! i used 10 guage because i got it free too. just keep an eye on it. feel it once in a while. put it on a 30A breaker to be really safe. i dont think it will trip. you can use the one you normally use for your dryer if you dont want to buy another one.

The MM175 will draw 19.5A from the 230V line.Hope that helps...Jay

It is common NEC (National Electrical Code) practice to protect #10 AWG wire with a 30 amp fuse or breaker, #12 is 20 amp, #14 is 15 amp. These figures can vary slightly depending on the wire type and installation., but as a general rule these figures are good

It is also standard engineering practice to size wire at 125% of full load. At 19.5 amps with 4/C #10, you are way under the max load....start welding.

Yep,
started welding today everything went great so far. I did notice the wire when I was wrapping it up was warm in spots but, welded great.
Thanks,
Mario(Dad)

oh yeah, just one small note to everybody. when using an extention cord, if you leave any of it coiled up, IT WILL CUT THE AMPACITY OF THE WIRE so always unroll it as much as possible when using something with a big load, like your welder

Greetings,

I realize that this is a little late for the originator however for

230 Volt Extension Cord features 25' of 8/3 power cable with molded NEMA 6.50 (pin) male (plug) and female (receptacle) at each end.

also available in optional 50' length.

This extension is ideal for your 230 Volt welder and will mate up with all standard Miller, Hobart and ESAB 230 Volt welders with factory supplied power cords and plugs.

I put mine together from a local electrical supply house. I got 20ft (I forgot what guage) but it's for outdoor use. The thick rubber jacket is what determines the price in most cases. As long as you're using it inside a shop in dry conditions, you don't really need it. But you never really know when a puddle shows up in the garage, so I got the outdoor one.

Dah! Come on. Not the transformer theory. You should see how many miles of sealtight flex are coiled up under computer floors. You don't loose anything worth talking about.

That is out of 310-16, but you have to use the correction factor for more than three current carrying conductors in 310-15(b)(2)(a), which is 80%. You are still okay at #10.

I think you'll find that the biggest problem with leaving extension cables coiled up is the danger of fire caused by the cable acting as a coil. Mig welders draw a lot more amps than computer cables.
During my time in the services as a lineman I actually saw a drum of partially uncoiled cable melt because of this.

Better safe than sorry.

I'm a licensed electrician by trade in NJ. As far as welders go in the code book, the gauge of the wire is determined BY THE SIZE OF THE WELDER AND DUTY CYCLE, NOT THE CIRCUIT BREAKER SIZE. Welders aren't continious duty. They have a very short duty cycle and as such, the wire is derated in size. It could be very possible to use #10 AMG for a 60 amp welder! At 240V, I would not be worried about voltage drop. Comparing a 240 volt circuit compared to a 120 volt circuit, both operating at the same wattage, the 240 volt circuit could be 4 times longer in distance before voltage drop becomes a problem. Ohms law.

Most likely you'll need 10/3 SJ or SJO cord, 50 foot will be no problem. You do not need a neutral because you do not have a 120 volt load.

Welders are covered under article 630 in the NEC

Hey you wire heads keep talking. This is one of the most informative threads I have ever read on this site!!

[302 Z28]

And...it will not hurt if the wire remains coiled.
