Special notes
TIG - Preheating of the base material is usually not necessary.
Do not keep the weld pool too wide. For build-up welding on ferrous materials
introduce as much filler metal as possible into the arc.
Preheat MIG - thick workpieces to +250°C. Do not keep the weld pool too wide.
For the 1st layer of build-up welds on ferrous materials, the impulse-
Arc welding is recommended.
