Custom-ground & ignition-safe: SVS standards for TIG/WIG electrodes
TIG/WIG electrodes are manufactured with high dimensional accuracy. The burr-free surface and the defined grind of the electrode tip ensure consistent arc guidance. The cylindrical base body ensures a precise fit in the collet and retains its shape even under thermal load. Depending on the application, variants are available with optimized ignition properties, high temperature resistance, or extended service life.
Available in various standard dimensions. We tailor the geometry and material precisely to your system and process requirements. Upon request, we also manufacture according to drawings or samples.
Options
Material options
Good arc stability with alternating current and reliable heat distribution for soft-melting materials such as aluminum and magnesium. The low mechanical hardness limits the service life at higher currents and dynamic loads.
Universally usable for AC and DC processes with good ignition behavior, a steady arc, and extended service life compared to WP. Suitable for stainless steel, unalloyed steels, and automated applications with stable parameters.
Good ignition response and arc focus, combined with low emissions. Service life remains stable even under changing process conditions. Particularly suitable for precise DC applications with minimal current fluctuation.
Long service life, very stable arc guidance, and precise heat input under direct current. Particularly advantageous for thin-walled materials or automated DC processes. Due to radioactive components, this product can only be used in compliance with appropriate occupational safety regulations.

Applications
The function of electrodes in TIG/WIG welding
In TIG welding, an arc is created between a non-consumable electrode and the workpiece. The electrode directs the current from the power source precisely to the joint and fixes the position of the arc in the shielding gas stream. The electrical energy is concentrated at the electrode tip, generating the necessary local heat to melt the base material.
Quality-relevant features of TIG/WIG electrodes
Not only the grinding angle but also the batch-to-batch consistency is critical. Variations alter the arc shape and affect welding parameters such as penetration depth and bead width.
Deviations in diameter or length tolerance affect the grip in the collet. Only precisely manufactured electrodes enable stable positioning and repeatable arc location.
Burr-freeness alone is not sufficient. The uniformity of the surface roughness also influences current transfer and thermal coupling. Irregularities in the contact area increase contact resistance and impede ignition.
The decisive factor is how evenly the components are distributed within the material. Only a homogeneous composition ensures controlled burn-off behavior and stable arc control over the entire service life.
More important than simple grindability is dimensional stability over multiple regrinding cycles. High-quality electrodes maintain consistent ignition frequency and geometric accuracy even after repeated reconditioning.
