In 2009 GYS, a French welding
equipment and battery charger
manufacturer, opened a new
R&D Centre. A major
development has been the
introduction of Power Factor
Correction (PFC) and
Flexible Voltage technology
across a range of MMA, TIG
and Plasma machines.

PFC is said to offer a host of
benefits, not least in reducing power
MMA machines will allow high duty
cycle welding at 160A (sufficient for
4mm rods) on a regular 13A power
supply.

GYS is also equipping machines
with Flexible Voltage
technology. GYS FV
machines can operate at
any voltage in the range
85-265V and are suitable
for 110V applications
and whenever there is a
likelihood of variations
in voltage.
