How To Install or Replace TOUGH LOCK Consumables

• 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.
