Tank EGW Vertical Seam Welding Machine

EGW vertical gas-electric welder is an efficient automatic welding equipment according to the current feedback closed-loop to control the welding carriage improve. In a single weld pass forced by water-cooled once molding thickness from 10mm to 50mm is the main characteristic of it. Molten pool liquid level automatic control at the same time, And the length of wire stretched out is automatic adjusted. With the small volume, light weight welding carriage and flexible modular easy to update, it's used convenient. Widely used in petroleum, chemical industry, the blast furnace of thick plate welding and shipbuilding and other industries.
