Stick electrode with basic special coating for welding brass and tin bronzes. Weld metal made of 6% tin bronze.

Most important applications
Copper-tin alloys, e.g. bronze with 4 - 8 % Sn, copper-zinc alloys (brass), copper-tin-zinc-lead casting alloys as well as build-up welding on cast iron.

Special instructions
For ignition, incline the electrode strongly and brush on. For non-ferrous metals, select electrode diameter equal to sheet thickness for sheet thicknesses up to 4 mm, preheating can be omitted. For wall thicknesses over 4 mm, preheating to approx. 250°C is recommended. For build-up welding on ferrous materials, direct the arc to the flank of the preceding bead if possible.

Generally not necessary.
The cladding tolerates re-drying up to a maximum of 250°C
