their explanations
Press the torch trigger
GPr
Gas pre-flow
I-S
Starting-current phase: the base material is heated up rapidly, despite the high thermal
dissipation that occurs at the start of welding
t-S
Starting current time
Start arc length correction
SL1
Slope 1: the starting current is steadily lowered until it reaches the welding current
I
Welding-current phase: uniform thermal input into the base material, whose temperature
is raised by the advancing heat
I-E
Final current phase: to prevent any local overheating of the base material due to heat
build-up towards the end of welding. This eliminates any risk of weld seam drop-through.
t-E
Final current time
End arc length correction
SL2
Slope 2: the welding current is steadily lowered until it reaches the final current
GPo
Gas post-flow

rameters"
