More power in a smaller cabinet
EFD Induction has introduced the world’s
first 1,000kW single-cabinet induction
welder – the first of its kind in terms of
power-to-volume ratio. According to
the company the new Weldac 1,000kW
offers less power consumption, better
weld quality and easier operation.
EFD Induction specialises in
developing equipment with the best
power-to-volume ratio possible. With the
introduction of Weldac 600-1,000kW it
can now offer up to 1,000kW in a single-
cabinet solution.
Weldac is part of EFD Induction’s
family of high-output, solid-state tube
and pipe welders. It is a proven solution
used over many years for welding low-
carbon high-strength steel, stainless
steel and aluminium.
The Weldac builds upon EFD’s
extensive process and applications
knowledge and decades of international
experience in solving tough welding
challenges.
The Weldac covers a wide range of
power sizes: from 50kW low-power
welders up to 2,200kW high-power
welders. All Weldac systems are backed
by EFD Induction’s extensive worldwide
service and support programme.
A modular design makes Weldac
1,000kW compact, saving valuable floor
space and simplifying in-line integration
and retrofitting. A 34 per cent smaller
footprint from EFD’s previous design
makes it even easier to install and
maintain.
Faster installation results in reduced
costs and retrofit downtime as well as
reduced delivery time on higher power.
Running costs are also lower due to low
power consumption.
What is known as ‘harmonic distortion’
is a growing concern, because the
proliferation of non-linear loads causes
disturbances that impair equipment
performance and affect total voltage
supply. A 12-pulse rectifier reduces this
by 50 per cent, resulting in a more even
temperature and a better weld quality.
The Weldac offers high total efficiency
measured from the mains inlet to the
weld coil. In combination with the
12-pulse rectifier, this minimises power
and cooling-water consumption.
The Weldac 1,000kW has longer
coil lifetime, resulting in minimal scrap
and re-working of material. This further
strengthens EFD Induction’s eco-
friendly welding policy.
The Weldac 1,000kW is easy to
operate, with a minimum of manual
settings. Operation is via an easy-to-
use control panel. Minimal operator
intervention results in fewer operator
errors and, consequently, increased
throughput and efficiency.

Burrmaster Rotoburr from Kent Corporation
KENT has developed a new Burrmaster
Rotoburr to complement its full line of
tube end deburring machines. The new
system is designed to remove the burr
from the ends of tube, roll form and
welded shapes.
The new, more economical machine
is manually loaded with deburrs one
end at a time. The steel deburring
brushes rotate at high RPM while the
entire brush head rotates a full 360o
to deburr every edge and corner. The
burrs from cut off saws and shear
blades are also removed, for safer
part handling. Large, more automatic
machines are also available, which
can be loaded directly from the mill or
manually. The parts are then picked up
one at a time and transferred through
the machine by chain driven fingers.
