Because the inverter is designed to inherently have low losses, smaller cooling fans are required. Shorter current paths translate to lower resistances and better efficiencies. The compact design and relatively small physical size of an inverter welder means shorter leads and cables (or even direct connections) between powerĬomponents. The energy needed for stick welding or for globular transfer welding processes is stored in capacitors allowing for smaller output chokes. Operating at higher frequencies than conventional welders, inverters require less output inductance for smooth operation. Copper has higher thermal and electrical conductivity compared to aluminum, which will minimize losses and maximize efficiency. The inverter's power electronic components have been carefully designed to reduce losses and extend operating life. A smaller coil translates to less wire wrapping around the core - less wire means fewer losses and greater efficiency. The inverter transformer coils are physically smaller than common transformers. This reduces the current losses resulting in lower idle currents in the supply conductors.


Greater transformer efficiencies are realized through the use of ferrite cores in the inverter's power transformer. Inverters can also save money in energy costs over traditional-type power sources since: In addition, inverters offer high-quality, multi-process welding capabilities so that one machine can handle Stick, MIG, TIG, FCAW, arc gouging and even pulsing. Inverters are more portable and lighter weight than traditional transformer-rectifiers, making them easier to maneuver around the job site. Power source that increases the frequency of the incoming primary power, thus providing for a smaller size machine and improved electrical characteristics for welding, such as faster response time and more control.
