Several aspects of an in-line welding gun are disclosed. In one aspect, the welding gun has a variable profile insulating boot disposed over the torch barrel of the gun. The variable profile insulating boot may be comprised of a molded material having varying thickness to provide the desired insulating properties. In another aspect of the welding gun, a speed control mechanism for the motor driving the wire feed assembly is positioned in a recess in the housing such that it reduces the risk of being unintentionally adjusted during operation of the welding gun. In another aspect of the welding gun, the wire feed mechanism features a feeder roller and an idler roller that may be separated without opening the housing of the welding gun. To separate the rollers, the user may depress a portion on the exterior of the housing to press on a pivotable lever on which the idler roller is disposed.
