New MIG consumables platform
TWECO, an ESAB brand, has
introduced the patent-pending Velocity
MIG welding consumables platform. The
contact tips feature shielding gas ports
that keep the tip 30 per cent cooler. By
running cooler consumable parts, life is
claimed to improve up to five times or
more in some applications.
The company will integrate Velocity
consumables on its Spray Master MIG
guns, along with retrofit kits for existing
Spray Master guns, and for the Classic
Number Series.
“Tweco Velocity establishes the
next generation range of MIG welding
consumables, and defines a new
standard of performance and life that
will drive increased productivity while
reducing costs for end user customers,”
said David Wilton, vice president,
welding products.
Gas porting in the contact tip, coupled
with an all-copper conductive path with
fewer connections, is claimed to improve
electrical and thermal conductivity.
Tweco states that its engineers have
demonstrated that the solution improves
conductivity and manages thermal
effects to achieve improved arc stability
by 15 per cent.
“Velocity is a result of our engineers
pursuing better arc characteristics
and contact tip life,” commented Ross
Fleischmann, senior brand manager.
“However, additional benefits were
achieved because we listened to
welders, and took the pain out of
maintaining MIG consumables.”
Because the contact tip runs cooler,
it reduces the ability for spatter to stick,
so the tip needs less cleaning. Fewer
threads and a careful consideration
of the thread design also deliver more
convenience and reliability. Extra threads
were eliminated by implementing a
thread-less, drop-in style contact tip.
Contact tips can be exchanged without
the use of tools.
Conventional designs employ soft
on soft thread designs made of copper
or brass, which can result in cross-
threading, seizing and premature
wear. Velocity employs a heat-treated
stainless threaded sleeve, which helps
alleviate these problems.
