Product Description
The EGW vertical gas-electric welder is a highly effective automatic welding machine that utilizes current feedback closed-loop technology to enhance control over the welding process. Its main feature is the ability to create a single weld pass with a thickness ranging from 10mm to 50mm, all while being water-cooled. The machine also automatically controls the liquid level of the molten pool and adjusts the length of the wire being used. Additionally, it is compact and lightweight, making it easy to use and update. This versatile welder is widely utilized in various industries such as petroleum, chemical, blast furnace, and shipbuilding.
