Product Description:

The Wieländer+Schill C-Arm No. 3 (474003NG) is a water-cooled electrode arm designed for extended reach resistance spot welding with the InvertaSpot NexGen Spot Welder. With a 150 × 450 mm working window, it provides increased throat depth compared to standard arms, allowing technicians to access deeper panel sections while maintaining stability and weld consistency. 

In collision repair workflows, this C-arm is used for OEM-style spot welding on structural panels, reinforcements, and mid-depth sections such as pillars, inner panels, and floor areas. It fills the gap between standard and long-reach arms, making it a practical daily-use option for Canadian collision repair shops working in professional shop environments.

Key Features:

• 150 × 450 mm working window for extended reach welding applications
• Water-cooled design supports high-load, continuous welding performance
• Designed for InvertaSpot NexGen resistance spot welding systems
• Includes C-shaped electrode with Ø16 mm electrode cap
• Built for consistent weld quality and maximum stability under load
• Ideal mid-range reach between standard and long C-arm configurations

Ideal For:

• Collision repair technicians performing OEM spot welding on structural panels
• Body shops across Canada working on pillars, inner panels, and reinforcements
• Mid-depth access welding where standard arms are too short
• Professional shop environments using NexGen spot welding systems

Common Questions:

Q: What is the C-Arm No. 3 used for?
A: It’s used for resistance spot welding in areas requiring more reach than a standard arm, such as pillars and inner panels.

Q: How does it compare to C-Arm No. 1 and No. 5?
A: It offers a mid-range reach, longer than No. 1 but shorter than the extended reach of No. 5, making it suitable for everyday structural work.

Q: Is this compatible with all spot welders?
A: No, it is specifically designed for Wieländer+Schill InvertaSpot NexGen Resistance Spot Welder and compatible electrode setups.
