General; Functions Of The Torch Trigger - Fronius MHP 280i G PM Operating Instructions Manual

General

General Welding torches with integrated wire drives are suitable for MIG/MAG manual welding
with long hosepacks, particularly when soft filler metals are being used. Two geared pre-
cision rollers ensure power is transmitted over a large area. This provides outstanding
wirefeed characteristics, even when using very soft aluminium or CuSi wire electrodes
and very long hosepacks.
The welding torches are particularly robust and reliable, with an ergonomic grip, ball joint
and perfect weight distribution for fatigue-free working.
Available as gas-cooled and water-cooled versions and in conjunction with the available
Multilock torch necks, the welding torches can be used in an extremely wide range of
applications. They are ideal for manual batch and single-piece production as well as for
jobs in the workshop.
