The Air N Arc® 300 system provides more efficient use of your truck bed and reduces cost by combining five power sources – rotary screw on-demand air compressor, 7 kW generator, 300A welder, 12/24V battery booster and 12V battery charger – into one single unit. Designed as a true two-generator system, the Air N Arc® 300 series allows multi-functioning such as welding and generator for lights for night time service.
