Special instructions
Guide the stick electrode with a short arc perpendicular to the base material. For larger workpieces and wall thicknesses over 15 mm, preheat the area of the weld joint to 150 - 250°C.

Re-drying
Generally not necessary.
However, the cladding tolerates re-drying up to a maximum of 150°C
