Technology news
CEMSA has recently launched onto the market a new
family of multi-head resistance welding machines named
“GRG – MPS”.
This new series is dedicated to the welding of stainless
steel or carbon steel wire panels, both basic and special
ones, like those used as shelves in supermarkets.
The panels accepted by the machine can be composed
by long and cross wires of different diameters as well as
by cross wires wires on longitudinal bearing bars.
The machine can operate by a shuttle tooling, either along
the length-wise axis (parallel to the multi-heads) and/or
along a 90° axis, perpendicular to the front, like in
integrated systems.
A similar machine can be offered equipped with a pallets
re-circulation shuttle, with automatic loading and
unloading, as well as with automatic wires feeder (hopper).
Heads can be 4, 6, 8, 10, or even 12 and 16, each fed by
an AC transformer, or with two AC transformers, working
in parallel and located besides the heads. This last
arrangement is convenient for medium productions, where
the mechanical cascade is within an acceptable time
frame.
45-60 kVA is the rating of the transformers fit to each
head, whilst 250 kVA is the suggested rated power of the
two transformers working in parallel. Therefore, depending
upon the production needs, it is possible to choose the
most suitable arrangement (all-together, electrical
cascade, mechanical cascade).
A more advanced alternative is the version with the
medium frequency (1,000 Hz) power package which is
recommended wherever the energy consumption is an
issue.
The control systems can be provided strictly in accordance
with the production needs to be effective either for simple
local management, up to fully integrated production lines.
