What Cable Diameter for MMA (Stick) Welding?

Welding cable diameter is generally selected on the basis of welding current level. The higher the current and duty cycle, the larger the diameter of the cable to ensure that it does not overheat (see relevant standard).

If welding is carried out some distance from the arc welder, it may be necessary to increase cable diameter to reduce voltage drop.
