General Remarks; Principle Of The Variostar Series; Machine Concept - Fronius VarioStar 2500 Bedienungsanleitung

General remarks

Principle of the The machines in the VarioStar series are MIG/MAG power sources and have outstan-
VarioStar series ding welding properties. Preset control processes, such as 2-step, 4-step, interval 2-
step, interval 4-step and spot-welding mode are self-explanatory. The machines are
manufactured in such a way that they function reliably, even in difficult conditions.
Powder-coated sheet steel housing, protection-mounted controls and central torch
connector meet the highest demands. The ergonomic recessed grip and trolley with
generously proportioned wheels facilitate transportation, both in-house and on-site.

Machine concept

The machines are characterised by their compact design, an integral drive system and
an integral wirespool holder.

Areas of utilisati- The field of application of the VarioStar series ranges from sheetwork to light steel and
on entrances. The easy welding capabilities of solid and flux-core wires of varying diame-
ters and alloys with different standard shielding gases extend the range of production
and repair applications.
