    Your earth clamp completes the circuit between your welder and the workpiece, and a poor connection here shows up as a weak, inconsistent arc no matter how good your technique is. This heavier 300 amp clamp handles more current and longer welding runs than the standard 200 amp version.

    If you're running a bigger MIG or stick welder, or doing longer passes at higher amperage, the extra rating here means the clamp won't heat up and lose its grip partway through the job.

    Straightforward to fit to your earth lead. Full specs are in the tabs below.
