Variante V (Fig. 5d) allows the welder to raise and lower the
welding current without an Up/Down torch.
The longer the torch-trigger rocker switch is pushed forward during
welding, the more the welding current is increased (up to maximum).
After the welder releases the torch trigger, the welding current
remains constant. The longer the torch trigger is pushed forward
once again, the further the welding current is reduced.
