You should be looking for SO type cable.

What kind of jacket is on welding cable?


As for gauge, I would look at 4. your standard Range plug from Lowes is 6.


Best deal; depends on your location.

Lowes only stocks SJ but Home Depot stocks SO. I am not sure what the largest size they have in 3 conductor is but I have bought plenty in 10-14 gauge.

NO.

At 100A, you are using either pin+sleeve connectors ($$$) or single pole connectors (Cam-lok).  If you use pin+sleeve, you can use type SO (assuming you can find 2AWG 4 conductor cable - and it's only rated for 95A).  Otherwise, you need to move to type W (again 2AWG or 4AWG 4 conductor cable, depending on temperature rating).  If you are using single-pole connectors, you need to use either type W or type SC, and can use 4AWG or 2AWG.

Your better to use single strands of #2  than a jacketed SO cord with all 4 wires inside. It increases the capacity per the NEC so you might be all right.

Opps... I didn't see that 100a... I was thinking for a small power disro using the 14-50 plug.

cant use welding cable as feeder cable. It was banned many, many years ago. Type SC is what you want. You can use type W but it is much more expensive, heavier, and difficult to work with.

SO cable would have to be used with pin and sleeve connectors (or
another multipin connector) Its not to code to 'fan out' a multiconductor cable and put camlocks on the ends. The individual conductors inside SO cable carry no ratings, not to mention its dangerous as the insulation is easily damaged. Last, you cannot have a single conductor feeder smaller than #2, except for the ground where #6 is permitted.

Historically we used J-Custom Supply.

They had best price/quality. Granted it has been nearly ten years since I have been in the market, but that was the go-to for many of us in the southeast US.
