The TRIMIG 385-4S is the latest easy
to use 3-phase 400V Synergic
MIG/MAG welder from
GYS, in which the
microprocessor controller
will automatically set the
optimum wire speed and
welding parameters,
thereby avoiding any
complex machine set up.

Designed for maintenance
and general light
fabrication welding using mild
steel, stainless steel and aluminium, it
is particularly suited to intensive
welding using 1.2mm diameter and
on occasion 1.6mm diameter welding
wires on either 200 or 300mm
diameter spools.

This machine is rated 370A at
25% duty cycle at 40°C and 210A at
100% duty cycle at 40°C.

Features include three
‘Easy Control’ welding
functions – normal welding,
spot welding with adjustable
spot diameter, and delay spot
welding with spot welding
time adjustment between two
spots. The ‘synergic welding’
mode provides fast and easy
set-up. Simply turning the
control on the front panel to
‘optimal synergic’ then inputting the
wire type, the wire diameter and the
power and the equipment will
automatically set the optimum wire
speed setting ready to weld.
