I am concern with the main side cables. The welding cables are properly rat= ed. 300 amps for insurance and it is properly insulated. Theinsulation is v= ery thick and can take heavy abuse.

If you are concerned about the welding cables then get proper cables for th= at use, which are very thick, and have insulation that will take the abuse = likely to occur in a workshop. >=20 > Here is the long story........ > I just got into welding.
