Tip Dressers

Over 20 years ago Stillwater worked with a customer who was experiencing problems with their robotic resistance welding operation. Their resistance welding robots weren’t as effective as desired due to the build-up of material on the weld tip after multiple welds. Stillwater assessed the situation and designed a way to remove the weld build up from the welding tip more quickly and efficiently than other products on the market. Discovering this was a widespread need in the marketplace, Stillwater created a product line of tip dressers. We have continued to improve upon our design and, as a result, Stillwater tip dressers are still the most sought after tip dressers in the market with over 10,000 sold to date.

Stillwater tip dressers offer the following advantages:

  • Lightweight, strong, and compact
  • 6061-T6 wrought aluminum (no castings to crack or break)
  • High torque values generated by heavy-duty gear train
  • Electric or pneumatic motor
  • Motor mounting options
  • Multiple standard cutter styles
  • Custom cutter designs
  • Engineering support
  • Rebuild / repair services

Threads or tapers, eroded contact pads, leaks, and bent parts are also repaired.
  • Following the repair each unit is tested for maximum performance and then shipped to you with a complete testing evaluation sheet for your reference.
