Product Description:

The Wieländer+Schill C-Arm No. 4 (474004NG) is a water-cooled electrode arm designed for high-load resistance spot welding using the InvertaSpot NexGen Spot Welder. With a 350 × 450 mm working window, it provides increased opening capacity and access for larger panel sections while maintaining consistent welding pressure and stability. 

In collision repair workflows, this arm is used for OEM-style spot welding on wider structural areas such as floor sections, cross members, and larger reinforcements. It is positioned as a heavy-duty, large-opening solution for Canadian collision repair shops that need both reach and capacity in professional shop environments.
