There has been some confusion around the term "synergic" welding machines in the industry and we wanted to add some clarity to the subject.
When a welder is referred to as synergic it means that when a single setting is adjusted (voltage, or material thickness, most commonly) the other settings (current, or wire speed) also change. On a pulse capable welder, there are a multitude of pre-configured settings being changed by the computer inside the welder to provide the best possible weld.
While a pulse capable welder is typically where you will find the application of synergic welders, you also can see this on some machines that weld exclusively in the short circuit.
