How To Install or Replace TOUGH LOCK Consumables


IMPORTANT:

  • Neck Insulator MUST be in place before welding to properly insulate the neck armor.
  • Check all parts to ensure that connections are tight before welding.
  • The heavy duty retaining head MUST be tightened with a 5/8 inch (16 mm) wrench to prevent the contact tip from overheating.
  • DO NOT use pliers to remove or tighten the retaining head or scoring may result.
