Welding Cable Lead Size???????? Help

[millerrules]

I have a bobcat 225 nt w/ no cables. I was wanting to put 50 feet of each. I would like to know if 2/0 gauge is big enough to do medium welding? Any help is appreciated.

The cable size is determined by amperage and length of lead. I would get cables to handle the max output of the welder but if you know you will never run that high then I guess it could save some $ to downsize. There is charts that should not be hard to find if you google it but I'm sure you're LWS has the chart handy. If you plan to by off the internet from a welding supply, they probably have the chart listed with the cable.

You will have no trouble at all with #2 cable, much smaller and cheaper than 2/0. weldersales

I agree, 2/0 is overkill for that machine especially for light general work. For giggles download the owners manual, its in there.

i have the same machine and i use 1/0 cable. i have about 75 feet for both cables. you should prepare to use your machine for anything that comes along. someday you may need to use it for something heavy. nice machine by the way.

According to Miller's own chart, #1 would be sufficient for 100 feet

This welding supply lists the chart.

Think 1/0 would be sufficient for any application you have in mind for your bobus

[Sberry]

Yes, 1/0 would be plenty and I would be tempted to add another 25 ft of lighter cable to the whip end. It would cost less, 50 ft might be plenty for ground but 50 is too short by a pinch for electrode holder. Also the small is going to be easier to drag around and cheaper to replace when worn.

If you go with 2/O, you will be fine. If you go with #2 and want to go further than 50', you won't. Go big if you can afford it. Sometimes the work is further away than you can get to! Trust me, it happens.
