Hexagonal Concentric Electrodes for C-Arm Electrode Holder, with Tilting

This detailed product description refers to hexagonal, concentric electrodes offered by Wieländer+Schill, designed for C-arm electrode holders and tilting mechanisms. These components are key elements of precision resistance spot welding technology, ensuring excellent quality welding results even on hard-to-reach surfaces.

Product Overview and Key Features

The product (Part No: 495679) contains a set of concentric electrodes specifically developed for use with C-arm electrode holders, complemented by a tilting (rocker) function. The concentric design allows the welding spot to be offset from the center outwards, which is critical for effective work in tight spaces and corners.

Main Advantages:

• Optimized Access: The concentric geometry allows the welding spot to be reached in areas where conventional electrodes no longer fit.

• High Accuracy: Precise positioning of the welding spot guarantees consistent and reliable weld quality.

• Durability: The use of CuCrZr (Copper-Chromium-Zirconium) material ensures excellent electrical conductivity and high mechanical strength, increasing the electrode's lifespan.

• Compatibility: Specifically designed for C-arm electrode holder systems, complemented by a tilting function.

Technical Data

The table below summarizes the product specifications essential for selecting the correct application and optimizing the welding process.

Application Area and Practical Advantages

These electrodes are ideal for automotive body repair work where the placement of welding spots is extremely tight. Combined with the tilting function of the C-arm electrode holder, the concentric electrode allows the welding spot to be offset from the center of the arm towards the edges, thus achieving the desired position without moving the welding machine arm.

Advantages of CuCrZr material:

The copper-chromium-zirconium alloy (CuCrZr) is considered a standard in resistance welding because it offers an excellent compromise between thermal conductivity, mechanical strength, and resistance to softening. This material ensures that the electrode tip maintains its shape and efficiency even under high current and repeated stress, minimizing wear and degradation of weld quality.

Concentric Design:

The „concentric” feature indicates that the electrode design allows access to the welding surface, unlike conventional straight electrodes. This is particularly useful on the complex structures of modern vehicles where welding reinforced or multi-layer sheets often involves restricted access. The tilting mechanism further increases flexibility, allowing fine adjustment of the welding angle without having to turn the entire electrode holder.

Connecting Accessories (Zubehör)

For effective operation, other products available in the Wieländer+Schill range that are compatible with or complement this system include:

1. Hexagonal Centric Electrodes (Part No: 495669):

• Centric hexagonal electrodes of a similar design for C-arm electrode holders, with tilting. These products may offer different variations for welding spot offsetting.

2. C-arm Electrode Holder with Tilt Switch (Part Number: 495688):

• This accessory is the holder structure itself, which enables the welding of very narrow metal seams. Working together with concentric electrodes, it penetrates every corner.

3. Electrode Cleaner (Electrode fix | Grain 60) (Part No.: 298298):

• Tool for cleaning the tip of the spot welding electrode when it becomes contaminated. Clean electrode tips are essential for achieving correct spot welding results, as contamination reduces the contact surface and increases resistance.

The combined use of these components ensures that the full potential of Wieländer+Schill's professional welding technology systems is exploited in the body repair sector.
