TOUGH LOCK™ Consumables


Innovative TOUGH LOCK™ Consumable Series can help to reduce your consumable costs and maintenance downtime.

TOUGH LOCK Contact Tips are manufactured from high-quality, high-conductivity copper using a mandrel-drawn process that controls tip tolerances. When mated with TOUGH LOCK Retaining Heads, they produce lower contact tip temperatures.

TOUGH LOCK Retaining Heads with Dual Taper Technology are manufactured with a tapered design at both ends that keep your consumables locked from contact tip to neck for improved weld consistency and to maximize heat dissipation, keeping your front end consumables running even cooler!

Need to get into tighter spaces?
TOUGH ACCESS™ Consumables are a sleek line of consumables (including retaining heads and nozzles) that allow entry into those hard-to-reach places that would otherwise be inaccessible due to fixture design or weldment.

Features and Benefits

  • Locking feature prevents contact tip and retaining head from overheating due to the loosening vibration often causes — cooler temperature reduces wear and extends consumable life
  • Greater surface area contact between the contact tip, retaining head and neck ensures better heat dissipation and guarantees positive electrical conductivity
  • Dual-lead thread design allows contact tips to be rotated 180° to a new wear position for extended contact tip life
  • Enjoy increased uptime due to less frequent consumable changes
