Milco designed a specialized gun with a very large throat and high pressure. This gun was used to weld the floor of Mack truck cabs to the sides and rear of the cab. This design is a modular concept and has been used for many similar applications with the ability to change the height and length of the welding window. The throat depth is 1400mm(55”), the tip force is 1000 pounds at 80 psi and it weighs 380 pounds.
