On first pressing the torch button, the pre-gas starts,
the arc strikes and the initial current will be used when
welding.
On first releasing it, the raising ramp of the welding current
"I1" occurs. If the welder now presses and releases the
button quickly, "I2" can be used; by pressing and releasing
it quickly again, "I1" is used again, and so on.
If you press the button for a longer time, the lowering ramp
for the current starts, thus reaching the final current.
By releasing the button again, the arc goes out and the
gas continues to flow for the post-gas stage.
