摘要： A method and device for controlling current flow through a welding clamp are provided. One welding clamp includes a first contact piece configured to contact a workpiece and to provide a first current path that limits current flow. The welding clamp also includes a second contact piece configured to contact the workpiece and to provide a second current path. When the welding clamp is being clamped to the workpiece, the first contact piece is configured to contact the workpiece prior to the second contact piece. In addition, the welding clamp is configured so that current flows through the first current path prior to flowing through the second current path when the welding clamp is being clamped to the workpiece.

摘要： A method and apparatus for welding is disclosed. The method includes sensing the status of a trigger between an on position and an off position. A system latch is set or released based on the trigger status and the latch status. The system latches on when the trigger is held for a predetermined time (and the latch was previously off). The latch is released when the trigger is pulled and released when the latch was previously on. When the latch is off, pulling the trigger turns the system on, and releasing the trigger before the predetermined time turns the system off. The latch may also be released when welding current drops below a threshold. The time might not start until after welding current is flowing. A welding wire feed speed control potentiometer on a torch is also disclosed. The range of the torch potentiometer is from a minimum to a value dependent on the control panel welding wire feed speed. A run-in wire feed speed control is also disclosed. The range of the run-in wire feed speed is from a minimum to a value dependent on the control panel or torch welding wire feed speed.

摘要： A shielding gas filter that can be readily incorporated into a gas shielding system for an arc welding apparatus. The gas shielding filter is readily installed to the system upstream of a gas solenoid valve and removes any potentially harmful particles from the supply of the shielding gas to prevent those particles from entering the gas solenoid valve. The shielding gas filter includes a housing having an inlet and an outlet and a specially formed passageway that communicates between the inlet and the outlet. A filter screen is retained within the housing to filter out the particles larger than a predetermined size. Preferably, the filter screen is constructed of stainless steel and filters out particles larger than about 100 microns.

摘要： Embodiments of a welding wire feeder including a pushbutton wire guide holder are provided. The wire guide holder may allow for the insertion and removal of a welding wire guide by depression of a spring-biased pushbutton and hold the wire guide with force applied by a spring. The pushbutton is disposed in a body, and a stop placed in contact with the pushbutton may prevent the pushbutton from being forced out of the body by the spring force. Some embodiments are directed toward holding inlet wire guides or intermediate wire guides, and therefore include different configurations of the body, pushbutton, spring, and stop.
