Just bought a Zeny 50 plasma cutter and I've never used one before. I will be using it outside in a paved area. Where should I ground the big alligator cable? Should I stick a copper pipe into the ground and clip it to that?


The ground clamp should be connected to the (electrically conductive) workpiece that you're cutting.

  • Make sure you're wearing all the proper safety equipment (gloves, eye protection, flame retardant clothes, etc.).
  • Work in an area that prevents others from coming too close.
  • Work in an area away from flammable materials.
  • Make sure you are familiar with the operation of the equipment, and safety gear.
  • Have a fire extinguisher nearby.
  • Don't burn yourself or anybody else.

    I see. What threw me off was that most videos did not do this but used a metal table. I'm assuming you can just connect it to the metal table and cut the piece on top of it? – swinefeaster Jun 22 '17 at 15:34

    @swinefeaster Yes, that's correct. If you're working on a conductive surface, you can simply ground to the surface. – Tester101 Jun 22 '17 at 16:34
