High output, reliable industrial machine

The Powertec range is the solution for Industrial applications. With modular and compact design this welding set is easy to move around site. With the latest high frequency inverter technology, the arc is precisely controlled, many times faster than conventional analogue power sources. The electrical characteristics of the welding power can be changed by software in real time updates. A wide range of synergic programs are available as standard allowing simple yet precise control of welding parameters for the best results every time. The Powertec machines utilise the very latest power source technology for efficiency and lower energy consumption.

Their advanced Inverter technology will save both time as well as energy. Driven by Lincoln Electric’s Green Initiative, we aim to reduce the costs to you as well as the environment. These welding sets are available as 350A/50%, 420A rated at 100% or 500A rated at 60% duty cycle (at 40°C). With the LF-56D wire feed unit the welding set can support the MIG processes with synergic programs for Steel, Stainless Steel, Aluminium and Flux cored wires. Stick & Gouging functions are available as standard.
