Abstract
A water cooled gas metal arc welding (MIG) gun which is provided with a water cooling system for the gun barrel that introduces the coolant water at the bottom of the barrel to create a coolant water flow through the gun that does not allow the coolant water to stagnate and heat up. The gun includes a water cooled shielding gas cup on the lower end that ensures coolant water flow therethrough, and provides metal thickness at the end of the cup which prevents physical abuse of the cup from affecting the guns' performance. The gun has a shielding gas delivery system which ensures good shielding gas flow and allows for replaceable shielding gas diffusers.
