Best way to strip 2/0 - 4/0 welding cable

Hey everyone,

What is the best way yall strip welding cable ( its stranded wire and flexible). I have a variety of sizes on what is considered welding cable. Ranges from #1 - 4/0.
I have bought a crank wire stripper but it didn't work. The blade just deforms the insulation and doesn't cut unless you have it deep enough to cut the copper to and that's even hit or miss.
So far all I have been doing is cutting it into short pieces about a foot and a half or so and just using utility knife. But I would like to find another way maybe faster. Since I have alot.
I don't want to buy an electric one if its not gonna work, cause they seem to be the same principle as the crank one I have.
I get this kinda wire over any other sizes. But I would also like to be able to do the smaller stuff to when I get it.

So any tip, tricks, advice is appreciated.

How much do you get and how often do you get it?

I got a good bit and it comes and goes on how often I get it. But I got a decent size pile built up I need to get knocked out. And I got a chance of trying to get alot more but I want a good way to get it done. Since its all thick stuff 3/0 and 4/0.

What about an angle grinder with a thin metal cutoff blade. Just go down the outside cable from top to bottom. If you are concerned with cutting too deep, make a shallow cut, then finish with a box knife.

I you've ever shucked an ear of corn this welding cable is a cinch, box cutter cut the first foot have your wife grab onto the exposed cable and you go off into the other direction pulling the insulation off. This works on rubber based covers if it's plastic then you'll have to lightly score the cables cover.

I've done miles of this type of wire.

Once the insulation is off, drag your hand along the cable to bunch up the paper crap, should be some synthetic string in there also, once you have a bundle and it no longer moves just use side cutters or grab that box knife to cut that nasty bundle off.

That cable would bring a better price re-sold to someone who is a welder, unless for some reason it's preferable to disguise the wire.

I don't get that much welding cable but i usually cut it into 12-18 inch lengths and run it through my electric stripping machine. The main problem is that the wire inside is a finely stranded wire and crushes easily. You have to set the cutter to a depth where it scores the insulation but doesn't really cut too deep. I pass it through a few times and that weakens the insulation enough that it peels off okay.

You've got the cutting wheel set a little too deep if the cable skitters off to the sides when you're passing it through. ( It's a fussy adjustment to get it just right.)

Jumper cables are kind of a booger to do because the insulation is so thick.

This is one of those tasks where a chopper / granulator would be the better tool for the job. You might just sell the welding cable at the yard as high grade insulated copper wire and save yourself all of the work. Figure one way ... you get ICW price. Stripping it probably wouldn't give you better than #2 copper price. There might not be a huge difference between the two where you are.

You just have to figure out whether or not the juice is worth the squeeze.

I want an electric stripper but didn't have the money at the time, and I don't want to spend the money on one for it not to work, so I bought one that I could attach a drill to, that looked to be tje.same as electric to see if it worked. But it didn't even score the insulation. The insulation just formed around the blade and went on through. Maybe If the blade spun at the same time it might would have.but the blade on the one just spins as the cable glides over it. The only way I could get a score was having it set to deep, it would stay center. I only tried a few pieces, so I'm sending it back. Do the wire feeder and the blades spin on the electric ones?
I've looked into granulators to, but that's way to much money for me.. unless there's some out there I couldn't find.
Any links to tools yall use or the info of tools used is appreciated as well.
If I could get caught up on it I think it would be worth it. I think last time I heard, insulated was .60 a lbs and #2 was 1. 50. But I haven't checked prices recently tho

You might check prices. They have gone up a bit.

You can use a board and a sheetrock screw. That's a low cost solution. The main thing is to get the hole through the board just the right size for the cable you are pulling it through.

Try home made wire stripper as the search term on youtube.

Ahh well ... gotta jet ... time to head out to the job.

I get 2/0 and 3/0 welding ables, the insulation is messed up so I'm scrapping it. But I will have a large amount of the insulation. Just wondering of what to do with it, instead of just throwing it away.

Another spoon feeder, are we gonna have to walk you through this whole process step by step.

What do you mean. I'm genuinely curious. I'm new to this whole thing. But I don't mess with any other scrap stuff. And come into the wire with possibility to get more.
I'm getting it done, just wanted to see if there's a better way to do things from people who are more experienced.
And with the wire insulation I have searched stuff but just wanted insight from experienced people.

The rubber insulation is classified as hazardous waste.

Next you'll say but it's not tires, yea yea but the components that make up the chemistry are basically the same and should be treated as such when disposing of said material.

You'll have to sharpen your pencil and factor in the cost of waste disposal when you eh purchase this cable. If you have a tire recap shop nearby check with them to see how they deal with rubber crumbs.

The biggest problem with discarding old tires is that they contain chemicals and heavy metals that leach into the environment as the tires break down. Some of these chemicals, according to the California Integrated Waste Management Board, are carcinogenic and mutagenic (cause cancer and gene mutations).

Applications of Crumb Rubber

Rubber crumb is sold as feedstock for chemical devulcanization or reclamation (pyrolysis) processes, added to asphalt for highway paving and pavement sealers, or used for the production of a large number of recycled rubber-containing products. Some of the major applications of crumb rubber are as follows: Sport Surfaces

• Kindergarten Playgrounds and Recreation Areas
• School Sports Areas
• Athletic Tracks
• Tennis and Basketball Courts

Automotive Industry

• Bumpers
• Splash Guards and Fenders
• Floor Mats for Cars and Trucks
• Floor Liners for Trucks and Vans

Construction

• Hospital, Industrial, and Bathroom Flooring
• Floor Tile
• Foundation Waterproofing
• Dam, Silo, and Roof Liners

Geotechnical/Asphalt Applications

• Rubberized Asphalt for Roads and Driveways
• Drainage Pipes
• Soil Conditioner
• Porous Irrigation Pipes
• Road Building and Repair

Adhesives and Sealants:

• Adhesives and Sealing Compounds
• Textured and Non-Slip Paints
• Roof Coating and Waterproofing

Shock Absorption and Safety Products

• Shock Absorbing Pads for Rails and Machinery
• Sound Barriers for Highways
• Abrasion Lining in Mining Equipment

Rubber and Plastic Products

• Pipe Insulation and Lining
• Garbage Cans
• Shoe Soles and Heels
• Wire and Cable Insulation

Your questions are fine and one purpose of the forum. For the most bang for your buck if you feel you have to strip it I'd go with one of the wire stripping machines you can find on ebay or alibaba that usually cost between $250-400. They have slots for several different gauges and adjustable blade settings and many do not require 3 phase power. I mostly don't recommend stripping wire unless it's for the fun of it. With a few exceptions like copper degaussing wire and a fair amount of 90% and above recovery wire, you can usually make *far* more $ selling the wire as is and spending the time you woulda spent stripping it on the phone calling electricians and asking to buy their scrap wire then selling it at a margin.
