brakes sufficiently before the welding wire runs
over the edge of the reel.
The brake force is dependent on the weight of
the wire reel and wire feed speed.

Connection of shielding gas
The shielding gas hose is fitted to the back panel
of the power source (3) and is connected to a
gas supply with a pressure reduction to 2-6 bar.
One gas cylinder can be mounted on the bottle
carrier on the back of a trolley if any.
Torch adjustment (Dialog torch)
The current size/wire feed speed can be adjusted
both from the machine and the welding torch if
a welding hose with dialog torch is in use. The
torch adjustment is passive without Dialog torch.
