The two gun welding machine has the following functions: The equipment adopts the integral design, the welding power supply is hidden in the equipment, the wire transfer panel forward, easy to adjust. The position of the argon cylinder is reserved. The overall safety and beauty of the cylinder. The noil and the frame are welded separately. The four frames are welded first, then the one in the welding, then the combined welding. It can be used for welding cross tint, tin tin, and T tin. The limit length of the welding is 250mm. The thickness range of aluminum profile is 140mm. This can be achieved by welding the upper and lower sides of the card, and the welding deformation is greatly reduced (two sets of welding gun for one device). The noil system can store up to 50 welding parameter information.
