4.0mm x 175mm Zirconium Tungsten TIG Electrodes (10 sticks) 40WZ8

DESCRIPTION

4.0 X 175MM ZIRCONIUM TUNGSTEN TIG ELECTRODES (10 STICKS) WZR8-4.0

Tungsten zirconium WZR8

WZr – Tungsten zirconium
Applications: TIG welding (welding of Al and Mg alloys)

For the WZr alloy type, up to 0.8% by weight of
zirconium oxide is added to the tungsten powder.
The alloy is used almost exclusively for TIG
electrodes. Because of its low alloy content,
the material is suitable to welding compounds
whose welds must be free of foreign material.
Furthermore, the alloy can also be used for welding aluminum and magnesium using alternating
current. It stands out compared to WP due to a
more stable arc.

Principle of TIG welding

Decisive factors
Modern inverter power sources with HF ignition and accurate power setting
Tungsten electrode: Size and composition
Electrode preparation: Cut, angle, seat of tip
Distance between electrode and workpiece, and distance between electrode tip and gas nozzle
Shielding gas: Quantity, composition, gas backing where necessary
Ambient conditions: Draft, extraction
Alternative SKU: WZR8-4.0
Part Number/SKU: 40WZ8-10
