## Product Description and Key Features<\/p>\n
The C-Arm No. 2 is a complete kit designed to enable efficient spot welding even in the tightest spaces. The kit includes the C-arm, an A electrode, and a water-cooled B-type electrode, as well as 13 mm electrode tips.<\/p>\n
**Key Benefits:**<\/p>\n
* **Optimized Accessibility:** Its geometry, specifically designed for work around wheel arches, allows welding in areas where conventional welding arms cannot reach.
\n* **Water Cooling:** The water-cooled design of the B electrode ensures increased electrode life and consistency of welding quality during repeated, fast cycles. This is critical for high-volume repairs.
\n* **Complete Set:** The package includes the necessary basic components (A electrode, water-cooled B electrode, and 13 mm electrode tips), making it ready for immediate deployment.
\n* **Durable Material Usage:** The arms and components are made of high-quality, durable materials such as aluminum, copper-chromium-zirconium alloy (CuCrZr), stainless steel, and rubber, guaranteeing a long service life and reliable operation.<\/p>\n

### Material Composition Details<\/p>\n
The C-Arm No. 2 combines several special materials for maximum performance:<\/p>\n
* **Aluminum and Steel:** The main structural elements of the arm ensure the necessary rigidity and relatively low weight.
\n* **CuCrZr (Copper-Chromium-Zirconium):** This alloy is crucial for the electrode tips and conductive parts as it provides excellent electrical conductivity and high thermal resistance, which is essential for withstanding the high currents and thermal loads that occur during spot welding.
\n* **Rubber:** Elements used for insulation and vibration damping.
\n* **PU Coating:** The polyurethane coating protects the metal structure against corrosion and mechanical damage in the workshop environment.<\/p>\n
## Application Context: Resistance Spot Welding<\/p>\n
The C-Arm No. 2 is an accessory designed for Wielander + Schill Resistance Spot Welding machines. During spot welding, electrodes placed between two metal sheets pass a high current, creating a thermal effect at the sheets' contact point, which fuses them together.<\/p>\n
Certain parts of wheel arches and vehicle underbodies often have internal or narrow spaces where standard, large welding guns cannot be optimally positioned. The special arm shape of the C-Arm No. 2 and its 95 x 55 mm working opening allow the welding spot to be precisely positioned exactly where required, minimizing the risk of damaging surrounding components.<\/p>\n
The water-cooled B electrode ensures that the electrode does not overheat during the welding process, which would inevitably reduce welding quality and quickly wear out the tips. Continuous cooling guarantees consistent welding resistance and perfect bead formation.<\/p>\n
## Related Products and Accessories<\/p>\n
The C-Arm No. 2 integrates excellently with other Wielander + Schill welding accessories for comprehensive repair solutions. Other elements of the product family that provide similar or complementary functions are as follows:<\/p>\n
* **C-Arm No. 9 (120 \u00d7 250 mm):** Another C-arm type, water-cooled, with 16 mm electrode tips.
\n* **C-Arm No. 3 (150 \u00d7 450 mm | GT):** A longer arm, covering a wider range of applications.
\n* **C-Arm No. 5 (205 \u00d7 550 mm | GT):** For welding tasks with greater reach.
\n* **C-Arm No. 1 (Standard, 150 \u00d7 70 mm | GT):** Standard, with a curved C-electrode and 16 mm tips.
\n* **C-Arm Electrode Holder Adapter with Tilt (No. 10):** This accessory (part number: 495604) is particularly useful for wheel arches as it includes a finger-type electrode and a narrow electrode, facilitating access where conventional electrodes are no longer sufficient. It guarantees the full functionality of the automatic mode.
\n* **C-Arm Electrode Holder Adapter with Tilt (General):** Used for welding narrow sheet metal seams, where the concentric electrodes, pushing the welding spot outward from the center, reach every corner.<\/p>\n
