1. Weight and Size: This is the most significant and impressive advantage an inverter welder has over conventional machines. For example, an inverter weighing less than 5kg, smaller than a suitcase and able to be comfortably slung over your shoulder, can have a comparable output capacity to a 50kg transformer-based machine. 2. Efficiency: Quality inverter machines, such as the Weldforce inverter welder range, will have an efficiency rating of about 80-90% while conventional welders have a significantly lower efficiency of about 50%. This is due to the fact that the larger transformers in conventional machines have greater resistance and therefore lose a significant amount of power (or energy) through heat dissipation.
