Frequently asked questions about tungsten electrodes
Which tungsten electrode for which material?
Roughly: WL15 (gold) and WC20 (grey) are universal for AC and DC. WP (green) for aluminium on AC, WT20 (red) classically for steel on DC. When in doubt, the universal grades are the safe choice.
What do the colour codes mean?
The colour code identifies the alloy / oxide additive. It is standardised (DIN EN ISO 6848) and marked on the electrode.
Which diameters are available?
Common diameters from 1.0 to 4.0 mm, standard length 175 mm. Current sizes in the product list.
