Tungsten electrodes, Purple, for AC/DC, Aluminium/Steel

• Multipurpose electrode. Steel/stainless steel with direct current, aluminium with alternating current
• The E3 tungsten electrodes (purple) are versatile. Their advantages are particularly evident when welding steel, stainless steel, copper and brass in the low and medium current range. Aluminium can also be welded in AC mode. Unlike thoriated electrodes, these electrodes are not radioactive. They are characterised by good ignition properties and uniform welds. They are suitable for automated welding.
