OPERATING PRINCIPLE
The welding machine manages automatically various parameters that allow a good
result of the welding operation:
FEATURES
HOT START
Generally when we start welding operation we have some difficulties because the
electrode and working piece are cold. During this phase the equipment supplies (for
a small time) the starting current with a value higher than value planed. This helps
the arc ignition and makes more stable welding process.
ARC FORCE
During welding operations the electrode is guided by the operator's hand, therefore
the distance from the welding point is not always the same. To avoid that electrode
approaching the welding melt creates a short circuit, the electronic equipment auto-
matically increases the arc current value to eliminate that.
ANTI-STICK
If during welding process we have a permanent short circuit, immediately the cur-
rent value decreases until the value to allow to the electrode be removed from the
melt and welding process can proceed regularly.
THERMAL PROTECTION
When yellow led is ignited is not possible to carry out the welding. Signal light is
switch off automatically when temperature goes down, now it is possible to weld
again. When equipment is switch on, signal remains about 3 seconds switched on.
During this time there is a check of all electronic functions and it is impossible to
operate.
