I see by Miller's recommendation that I need the 2/0 welding cables for a Miller Bobcat 250 or 225. What say you guys? Could I get by with a smaller size. Cyberweld wants $408 for them. Yikes! Would a really good set of jumper cables do? (just kidding)! I think I saw an earlier post that said #2 wire would be just fine but I've been told there's a difference between welding cables and plain old insulated copper wire. Thanks again in advance for everyone's expertise. I have learned a bunch from this forum.
Reply:Oops. I'm sorry. They're $480. Not $408.

Reply:I would just look on craigslist, Im sure you could find some used ones for a decent price.
Reply:2/0 is too big. I had it for my Lincoln G7 and it just wasn't needed. It makes for a heavy stinger. #2 is too small in my opinion. I don't care what the chart sez. #1 would do a fine job. I use #1 for my ranger 250 and have a #2 whip and stinger. For 1/8" its fine. I can get it warm with 5/32 rod (190 amps).David Real world weldin. When I grow up I want to be a tig weldor.
Reply:The charts DO matter . the lengths are decided by the amps you are going to use. There is no fooling the laws of physics (nature) . When you need big leads,there is no substitute. Just like trying to make do with a 100 amp welder , when you need 200 amp machine . And, the chart will show that the longer leads you need , the bigger they need to be . ($$$)[SIZE="5"Yardbird"
Reply:MY LWS said #2 would carry 200 amps 50' It gets warm with 12 feet. That is why I don't believe the charts. There is a chart copied from the bible in this thread Post # 16http://weldingweb.com/vbb/showthread.php?t=24558Now that I look, musta been the duty cycle I had it on my LN-25David Last edited by David R; 10-21-2008 at 09:42 PM.Real world weldin.

Reply:Thanks for the info, guys. Miller's cables are 50 feet long....I suppose you could get by with shorter ones but If I happen to be welding some fence braces where I can't get the trailer to, having 50 feet would be nice. I have checked Craigslist in the DFW area but no luck on just cables. Miller's #2 cables are half the price of the 2/0, so I'm guessing #1 cables ought to be somewhere in between the two price-wise. I have done almost no stick welding since I bought my Millermatic several years ago so I'm not sure what problems I'd encounter if I get too small a cable. I suppose they wouldn't carry the current and the welds would suffer....of course we're talking rusty oilfied pipe here.
Reply:If you're welding (your own business ) for hire , you'll find you always need more cable than you have . I stopped at 175 feet (stinger) &100 feet (ground) of #1/0 cable. And ,occasionallysomeone wanted me to have MORE cable to a more remote site. I always turned down those jobs , they were invariably small jobs that would not have paid for even a little bit of cable. I was lucky when i bought my cable, got it from a friend who was a Belden distributor, in 1981, for 75 cents a foot. cheap, even then . Another tip for newbies; keep a spare stinger with your truck, maybe two or 3 . I liked to have a small one for 3/32 rod, a regular one , and a BIG sucker for 3/16 rod. the bigger the stinger , the bigger the stinger lead . The leads being about 10-12 feet long with quick disconnects, of course.[SIZE="5"Yardbird"
Reply:Well, I don't plan to advertise myself as a 'welder'. You guys would laugh if I ever posted pics of my work. Some of the welding samples I've seen on this board are beautiful and you are all to be lauded for your skill. I'll just be doing various projects on the farm but I like to have the right tool for the right job. Even though they're pricey, sounds like I should just 'ante up' and get the cables Miller recommends. Thanks again. |
