ArcStar KBM Petrol Kohler Engine Driven Welder Generator

The ArcStar KBM Petrol Welder Generator is a cost-effective and reliable solution for mobile welders. Ideal for use from a van or out in the field, it’s well-suited for on-site work such as construction jobs or agricultural repairs.

Built with a durable, modern design, this unit is powered by a Kohler CH440 (Stage V) 4-stroke, air-cooled petrol engine with a 6.1-litre fuel capacity. Running at 3000rpm, it delivers up to 11.1HP (8.2kW standby), providing dependable performance in demanding environments.

Equipped with both 110V and 230V 16A outlets, the generator can power a range of tools including angle grinders, as well as site lighting and other equipment.

Designed for MMA welding (lead set not included), the ArcStar GW5-200 KBM offers a duty cycle of 170A at 60%, with an adjustable amperage range from 40A to 200A.
