This detailed product description refers to the high-performance, water-cooled C-Arm 5-axis type, featuring a 205 × 550 mm work area, GT version, offered by Wielander + Schill, specifically designed for resistance spot welding applications. This component is crucial during automotive body repair and semi-industrial work where achieving reliable and precise welding results is essential.
A C-Arm 5-Axis Type (GT) A robust, water-cooled C-type welding arm designed to ensure optimal access and stability for the most demanding spot welding tasks. The water-cooled design is critical during continuous, high-intensity welding cycles as it efficiently removes heat from the electrodes and the arm structure, thus maximizing electrode life and ensuring welding quality consistency.
The product is a fundamental accessory for the welding system and includes as standard equipment one electrode and two 16 mm diameter electrode tips (electrode caps), ensuring immediate readiness for operation. The GT (Automotive Technology) designation indicates that this arm is ideally integrated into modern vehicle repair processes where precise machining of tight spaces and specialized body panels is required.
The design of the C-Arm allows access to weld spots in areas where conventional welding guns cannot reach, particularly on internal body reinforcements or hard-to-reach joints.
Water Cooling: The integrated cooling system ensures the optimal temperature of the welding arm and electrodes, which is essential for maintaining long service life and stable welding parameters.
Extensive Work Envelope: The 205 mm x 550 mm work block (Work window) allows for reaching welding points over a wide range, providing flexibility for various body-in-white components.
Standardized Connection: The 16 mm shank diameter ensures compatibility with standard welding systems and a wide selection of available electrode tips.
Complete Delivery Package: The set includes the C-arm itself, one electrode, and two 16 mm electrode caps, so the user can start working immediately.
Robust Material Usage: The arm construction consists of a combination of aluminum, copper-chromium-zirconium (CuCrZr), rubber, stainless steel, and steel elements, guaranteeing mechanical strength and excellent electrical conductivity.
