Industrial welding package
Weldability-Sif, a UK-based ‘one-
stop source’ for welding products,
has launched the SifWeld MTS 400
electronically controlled MIG/MAG/MMA
industrial welding package featuring
IGBT inverter technology.
With clear digital displays, low-spatter,
polarity reversal (for FCAW) and
integral four-roll wire feed system able
to accommodate up to 15kg of wire
spools, the unit is designed for use
in heavy-duty fabrication applications
such as structural steel and marine/
shipyard tasks.
The SifWeld MTS 400 can be used
to weld mild steel, low-alloy, stainless
and aluminium in solid and flux-cored
MIG applications. It can also be used
for DC MMA welding (DC+/DC-) and
scratch-start TIG welding. Its control
system allows infinitely variable control
of welding voltage, wire feed speed,
crater current and burn-back. The power
source also benefits from 4T/2T torch-
latching and gas line purging. It offers a
high duty-cycle for applications requiring
long runs, and features adjustable burn-
back control.
The separate, removable four-roll wire
feed unit offers four gear driven rollers
and a counter-balanced wire tension
system for precision wire feeding.
The wire feed unit houses the wire
feed speed and voltage controls as well
as the wire-inching feature, to provide
complete control of feed rate when used
remotely via the interconnecting cables.
The ergonomic design of the SifWeld
MTS 400 incorporates an integrated
MIG torch holder for easy storage, and
a wire spool cover to protect wire from
the elements.
A robust trolley accommodates a full-
size gas cylinder and includes a wire
feed unit mounting bracket, which allows
the feed unit to rotate a full 360° while
ensuring that the interconnecting cable
is secured via the attachment bracket.
The trolley also features a storage
compartment for common spare parts.
The SifWeld MTS 400 features MIG,
MMA and Smart-TIG functionality,
comes with a 400V 3ph 32A input supply
and supplies 400A DC output at 100 per
cent duty cycle.
