stood these Operating Instructions.
the Operating Instructions for the system components, in particular the safety rules!
Gas pre-flow time
Spot welding time
Starting-current phase:
Carefully warm up with low welding current to position the filler metal correctly
Final current phase:
To avoid local overheating of the base material by heat accumulation at the end of
the welding. This eliminates any risk of weld seam drop-through.
UpSlope phase:
Continuous increase of the starting current to the main current (welding current) I1
Continuous reduction of the welding current to the final current
Main current phase (welding current phase):
Uniform thermal input into the base material heated by advancing heat
Reduced current phase:
Intermediate lowering of the welding current in order to prevent any local overheat-
ing of the base material
Gas post-flow time
