V 30

Stable arc – at DC and AC.

The V 30 is available as a DC and AC/DC version on any performance output level. The V 30 stands out particularly with its highly stable arc. The arc shape is optimised for excellent cleaning effect of the aluminium oxide layer and for reduced noise alike when welding with AC. The AC/DC version has an automatic cap shaping function as well. Its square-wave current gives the V 30 additional boost and greatest arc stability when welding aluminium.

The V 30 housing is robust and secure.

The high-end technology inside the V 30 is protected by a robust industrial metal housing that is ideal for outdoor use. The fully resilient handles allow suspension of the power source from the crane and hold the welding cables. The double gas cylinder safety device maximises safety within the production environment.

Pulsing and fast pulsing at up to 20 kHz.

The integrated pulse and fast pulse function at up to 20 kHz is particularly suitable for welding thin sheets. It also permits outstanding weld pool control for perfect results even with difficult welding tasks.

Energy efficiency at full power.

The integrated stand-by function ensures turns individual components on and off automatically. The Thermocontrol sensors monitor system temperature and adjust the fan as required to reduce fan noise, dust load inside the machine, and power consumption.

Optimal parameters with the SmartBase.

SmartBase technology guarantees a perfect arc matching your chosen electrode diameter with welding parameters, ignition, and working range automatically adjusted and optimised. The arc can be fine-tuned individually for best freedom and to warrant welding with the optimum arc.
