• 6" chucks are not recommended and may cause motor drive failure.
• Purge Gas Manifold Kit sold separately for purge applications.

Why Use a Welding Positioner?

• Improves Weld Consistency: Maintain steady torch movement and travel speed.
• Reduces Fatigue: Let the machine rotate the part instead of repositioning manually.
• Boosts Productivity: Faster setups and more efficient welding cycles.
• Cleaner Welds: Better positioning leads to improved weld appearance and quality.

Recommended Accessories

• 2.5" Chuck – Micro chuck mounts directly to spindle (replaces table plate)
• 4" Chuck – Traditional 3-jaw chuck with key mounts to table plate
• Purge Manifold Kit – Enables center purging through spindle/chuck
• Articulated Arm Rest – Improve comfort and weld stability
• Adjustable Wrist Rest – Reduce fatigue and improve control

Frequently Asked Questions
