Machines offering multi process features are gaining popularity

Welding machines with multi-process capability have quickly earned favour amongst welders and it is with good reason as they offer features that do the work of several products.

At the core of any modern welding machine is an inverter, simply put, it converts the low frequency 50Hz supply into a high frequency 25 Khz to 150 Khz supply which when used with a corresponding transformer reduces the weight considerably. Think of the inverter as an engine and think of the functions of the welder as things you can do with an engine. It quickly becomes clear that multi process machines simply share the inverter and each functional output whether it is AC or DC welding current, MIG or Plasma capability is a manipulation of the step down transformer’s output.

In the comparison table below each multiprocess feature is contrasted against a corresponding welding machine to allow for the easy comparison of welding processes.
