Safety
WARNING!
WARNING!
An electric shock can be fatal.
If the power source is connected to the grid during installation, there is a danger of serious
personal injury and property damage.
▶ Only carry out work on the device when the power source’s power switch is in the -
O - position.
▶ Only carry out work on the device when the power source has been disconnected
from the grid.
Danger of electrical current due to electrically conductive dust in the device.
This can result in severe personal injury and damage to property.
▶ Only operate the device if an air filter is fitted. The air filter is a very important safety
device for achieving IP 23 protection.
General Commissioning is described with reference to a manual, water-cooled MIG/MAG application.

Brief description
of MIG/MAG
standard synergic
welding
MIG/MAG standard synergic
MIG/MAG standard synergic welding is a MIG/MAG welding process covering the entire
power range of the power source with the following arc types:
Dip transfer arc
Droplet transfer occurs in the lower power range during the short circuit.
Intermediate arc
The droplet increases in size at the end of the wire electrode and is transferred in the
mid power range during the short circuit.
Spray arc
A short circuit-free transfer of material in the high power range.
