The material used for the contact tip and the bore diameter both have a decisive impact on the service life of the contact tip. We therefore offer E-Cu, CuCrZr, and WQ contact tips.

CONTACT TIPS FOR WELDING TORCHES
The contact tip is the smallest, but the most important, wear part in MIG/MAG welding, and has a major impact on the quality of the welding process.
It transfers the welding current to the wire electrode and, with a constant flow of current, guarantees a stable arc. But which contact tip is best for which welding application?

Ideal for steel and CrNi welding.
E-Cu contact tips are made from pure electrolytic copper and boast outstanding electrical conductivity and good thermal conductivity.
Electrolytic copper softens at around 260°C and has low wear resistance.
E-Cu contact tips are primarily used in the low ampere range for manual welding applications.

Ideal for steel/CrNi and aluminum/CuSi welding.
The CuCrZr contact tip is made from a copper-chrome-zirconium alloy.
These alloy elements make its electrical conductivity slightly lower than that of the E-Cu contact tip, but its temperature resistance extends up to 500°C. CuCrZr contact tips are right at home in the medium to high ampere range for manual and robotic welding applications.

Ideal for steel and CrNi welding.
The WQ contact tip (tungsten-copper quality) is an E-Cu contact tip with a tungsten-copper core. The high temperature resistance of tungsten is impressive and combines perfectly with the high electrical and thermal conductivity of copper. Applications where grinding might be involved will particularly benefit from a WQ contact tip. System availability increases and maintenance costs fall.
