Weldac 1500
A product within the Weldac family

®

Less power consumption, a smaller footprint and easier operation are three hallmarks of
the latest generation of Weldac systems. These features, coupled with the reliability of IGBT
transistors, translate into:
More uptime
EFD Induction’s patented switching pattern lets Weldac use rugged IGBT transistors. These transistors are virtually short-circuit proof, considerably boosting
Weldac’s reliability.
More output
Continuous electronic load matching secures full power output across a wide range
of tube sizes, ensuring maximum welding speed for each size. No operator action is
needed, simply change the coil size.
Lower costs
Weldac’s efficiency from input at the rectifier to output at the
coil is 85-87%. Cooling water consumption is low, with no need
for expensive de-ionized water. Weldac eliminates the need for
costly reactive power compensation capacitors by using diode
rectifiers that result in a high, constant power factor (0.95) at all
power levels.
