Abstract: A hermetic pressure connector which provides a pressure-tight, electrically conductive connection through a hole in a bulkhead. The connector includes a transverse support member having a high pressure side and an opposite low pressure side. A passage extends through the transverse support member between the opposite sides. A conductor pin having an axial portion extends through the passage. An insulating sleeve surrounds at least the axial portion of the conductor pin, thereby electrically insulating the transverse support member from the conductor pin. A molded connected body surrounds at least a central portion of the conductor pin at least at one of the high and low pressure sides to thereby mechanically support the conductor pin in the passage. The molded connector body is directly sealingly engaged with the conductor pin, the insulating sleeve and the transverse support member.

Abstract: 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 include 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.

Abstract: A welding gun includes a motor, a wire feed mechanism, a power block, a welding tip, a and a cup. A substantially rigid shell surrounds the motor to form a handle. The gun includes a spindle, a spool and a quick disconnect mechanism for coupling the spool to the spindle.
