Special instructions
Guide the electrode as perpendicular as possible to the seam. Preheating is only necessary for large workpieces. For build-up welding on ferrous materials, direct the arc to the flank of the preceding bead if possible.

Re-drying
Generally not necessary.
The cladding tolerates re-drying up to a maximum of 70 - 90°C
