Welding instruction
Opening angle of the prepared seam approx. 70 °C, root gap approx. 2 mm. Weld stick
electrode with slight tilt and with a short arc. String beads are welded. The interpass temperature
of 150 °C and a max. weaving width 2,5 x diameter of the stick electrode core wire
should not be exceeded. Re-dry the stick electrodes 2 – 3 hours at 250 – 300 °C before use
and weld them out of a warm stick electrode carrier.
