Product Questions and Answers

How to install work clamp:

  1. Use the right tools.

    Do not just hand tighten hardware. Use proper tools. A loose electrical connection will cause poor weld performance and excessive heating of the work clamp.

  2. Position cable.

    Work cable should be routed through the opening in the clamp handle.

  3. Secure cable.

    Tighten cable using a wrench to secure the lock washer and nut on the screw.
