Stabile connection in the torch head: SVS standards for nozzle holders
Manufactured with high dimensional stability and tight dimensional tolerances, nozzle holders ensure the precise positioning of all components in the torch head. The materials are designed to withstand thermal and mechanical stresses and retain their shape even during extended duty cycles. Optimized flow channels direct the shielding gas evenly to the welding zone, preventing turbulence.
Available in standard designs and customized solution based on drawings or samples. We tailor interfaces, materials and geometry precisely to your torch type and process requirements.

Applications
The function of nozzle holder in MIG/MAG welding
During the welding process, the nozzle holder performs several interface functions within the torch head. It establishes the current transfer to the wire electrode, holds current-carrying and gas-carrying components securely in position, and guides the shielding gas toward the arc.
At the same time, it absorbs heat generated at the contact surfaces and dissipates it into the torch body. Its role as a connecting element under mechanical and thermal stress makes it crucial for process stability during continuous operation.
Quality‑relevant features of MIG/MAG nozzle holders
The material must reliably transmit current, dissipate heat, and retain its shape even under prolonged stress. The decisive factor is the combination of conductivity, strength, and temperature resistance.
Only with tight manufacturing tolerances can the contact tip, gas nozzle, and wire guide fit precisely within the system. Deviations lead to inaccurate fit, unstable gas flow, or contact failures.
The surfaces through which the current is conducted to the wire must be cleanly machined and dimensionally stable. This is the only way to ensure low contact resistance, stable component alignment, and reliable arc guidance.
For system compatibility, it is crucial that interface dimensions are manufactured precisely. Even minor deviations in threads or mating surfaces hinder assembly and disrupt the fit within the burner system.
