An inverter-based welder provides many benefits over traditional copper wound transformer machines. The most notable benefit is that of size and weight. An inverter is smaller and is a fraction of the weight of a transformer based machine so it is far more lightweight and portable. Inverters use a lot less input power to get the same output power than the older transformer type machines, so they consume a lot less electricity and therefore are greener to run.
As an inverter's power output is controlled electronically there is an infinite amount of power adjustment. In most cases (and featured in all our machines) a rotating control knob is used to adjust the power output of these modules, thus allowing fingertip adjustment between 0 and 100%. This enables the user to accurately and very finely control the welding output to suit any given application. It is usual to find that traditional welders have a number of step settings. These have limitations where setting 2 might not be powerful enough but setting 3 is too much. Using an inverter-based welder allows you to set the welding power output exactly where you want it.
