The set UPS-1250A is designed for the argon-arc welding (a welding with non-consumable electrode) of the longitudinal welds of the cylindric and other parts with a length of up to 1250 mm in workshop conditions. The set helps to raise labour productivity during the welding works, and to achieve a high quality of the welding joints.
