Or you have been lucky. Back when I played fire fighter. A homeowner had
one of those fancy roll up extension cords. Well he has something plugged into
it in his basement and only like 5 feet of 50 unrolled. Some time in the middle
of the night I melted down and started a fire. House was a total loss for being
lazy.

So go ahead and leave the rolled up, take video of the fire so you can entertain
us.

We had a reel in the HT shop on the Destroyer. Their was 800 feet of welding
lead on the reel. Every 50 feet was a connector so we would unwind to the
next connector and then hook that to the welder. So there was never current
running through the coiled lead.

I won't run them either.

Yes, another vote for do not use leads whilst they are still coiled on drums.

I have seen many extension cables melted together due to being used coiled tightly on drums.

As for welding cables on steel drums, a transformer is a coil of cable would around an iron core so in addition to the heating problems you can get all sorts of strange electrical effects occurring.

Reels keep from twisting assholes in to the cables from coiling.

If you use non-ferrous matl. for the spool, the inductance of an "air core" coil isn't going to effect the arc measurably, I'd bet.

LOL, I'll take that bet ...

The current flowing through the leads (or an extension cord) can heat them up. As they heat up, the resistance will increase, as will the heat. Normally, air will cool them. But if the cables are stacked closely, they MIGHT heat up. At least in my mind this is the "science" behind fires or meltage.

If you are just looking to hang the cables somewhere, cut an old wheel in half, clean the sharpys from the halves, weld on tabs to mount them, then hang the cables from them...

I would still recommend reels to roll up and store the cables. It is so much faster to just pull the cable straight out and double back with the cables pulled straight and not dealing with a coiled mess. And stored much neater, especially if you have a long set.

Shade had a good suggestion with quick connections, so you only use want you need. However, remember each connection is more chance for corrosion and added resistance, plus cost.

I would keep one shorter set about 25’, and then maybe a 100’ set, depending on what he will be welding.

"the inductance of an "air core" coil isn't going to effect the arc measurably, I'd bet."

I'm with Shade on this one; former job (35 yrs) in industrial instrumentation, part of my job involved induction heaters - one type used the "client" (an 8" diameter 24" long "billet" of Zirconium alloy, DEFINITELY non-ferrous) as a "core" - the heater coil drew 500 amps, and would heat that billet from room temp to dull cherry in about 15 MINUTES.

After that the billet was placed on a mandrel and pushed thru another (different alloy) and much larger billet by a 1000 TON hydraulic press, to form a co-extruded tube (nuke plant cooling pipes)

I don't (yet) have my stick leads on spools, probably never will; but I DO have 'em in sections with connectors; longest section's 25', stinger is on an 8' whip.

When I got the little green stick/tig inverter, made adapters to use all my leads with dinse plugs. Made a 6/4 extension cord, 85 feet. Now if necessary I can weld (stick) as far away as 140' from a 240 outlet WITHOUT firing up the genny. Up to 100 feet with wire (the little "offroad" mm211)

Definitely NOT a pro, but it works for a cranky old "hobby farmer/mad scientist" ... Steve
