Weldfast MMA1197 Earth Clamp Magnetic 600Amps
A magnetic earth clamp for welding, rated up to 600A. A magnetic earth clamp is a good alternative to a standard crocodile or earth clamp with jaws where clamping onto the job is not possible.
This magnetic earth clamp simply magnetises to the work piece or welding table. The earth lead is attached to the clamp with grub screws, clamping onto the copper strands of the cable.
The magnet earth connection can be used for MIG, TIG or Stick welding.
A lot of welding related issues can be traced back to a bad earth, so its always worthwhile checking condition and replacing if required. The earth clamp and welding leads should be suitably rated to the machine being used. If too much current passes through the lead, it will get hot, can get damaged and could be a fire risk.
