The Weldac is extremely easy to operate, with a minimum of manual settings. Minimal operator intervention results in fewer operator errors and, consequently, increased throughput and efficiency. Coil changes take only seconds, with the frequency adjusting automatically to each tube dimension. 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.
Weldac’s efficiency is one of the best in the market. 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.
While the well proven IGBT transistor still is the main power transistor with high-current capability, EFD Induction will also offer SiC transistors as an alternative where they are of benefit to our customers.
Weldac is supported by a global network of EFD Induction factories, workshops and offices. Wherever you are, after-sales service and support is never far away. You can also benefit from our ongoing program of operator training courses and component upgrades. EFD Induction has the most comprehensive range of solutions for the tube and pipe industry. We offer a full range of consumables including coils, ferrite, impeders and tube scarfing equipment.
