Simple Setup

Old power sources are difficult to set up, wasting time. New Syncrowave machines are simple to set up and have exclusive Pro-Set™ technology, which allows one-touch parameter setting to increase productivity.



Outdated machines consume more primary power, which drives up costs. New Syncrowave machines are up to 33% more energy-efficient than older machines, improving your bottom line. Moreover, Syncrowave 300 and 400 are compliant with EU ecodesign requirements for welding equipment, applied from 2023.


Smaller Footprint

Big, heavy power sources get in the way and are hard to move, making it more difficult for welders to do their jobs. Smaller, lighter Syncrowave machines improve workplace conditions.


Easy to Use

Complicated power sources can actually slow work down if your welders don’t understand how to use them. Syncrowave machines have an intuitive user interface, so they’re simpler to operate and more work gets done.


Stable Arc

If a power source doesn’t deliver a stable, controllable arc, it can result in lower productivity and higher costs. New Syncrowave machines have more stable arcs, making it easy for any welder to get more done and do better work.
