摘要： A control pedal for a welder that controls the output current level of the welder. The control pedal includes a foot pedal, a start switch, and a current level controller. The foot pedal is movable between an off position, an intermediate position, and a fully on position. The start switch initiates a startup sequence for the welder. The current level controller produces a signal that causes the output current level of the welder to vary between a minimum and a maximum current level. The foot pedal causes the start switch to begin the startup sequence prior to the foot pedal causing the current level controller to generate a signal which results in the output current level increasing above the minimum current level.

摘要： A mechanical power switch for selectively connecting a power source to an input power supply where the power source has an override circuit to deactivate the power source when in a first condition and allowing activation of the power source when in a second condition. The power switch has electrical contacts movable between an open condition with the power source electrically disconnected from the power supply and a closed condition with the power source electrically connected to the power supply and an operating lever movable between a first position with the switch in the open condition and a second position with the switch in the closed condition. An auxiliary switch in said override circuit has a movable element with a first orientation to shift the override circuit into the first deactivate condition and a second orientation to shift the override circuit into the second activate condition. The switch lever of the main switch causes the movable element of the auxiliary switch to move into the first orientation before the lever moves to the first position, but during movement of the lever from the second position to the first position.

摘要： A rotative mounting arrangement for a wire supply reel off which the coiled wire thereon is fed by feed rolls comprises a reel mounting spindle axially and rotatively locked within the hub of the reel and provided at its exposed opposite ends with mounting journals for rotatively supporting the spindle in upwardly opening V-shaped trunnion type journal bearings. The spindle journals and trunnion type journal bearings are formed with axially facing cooperating bearing surfaces axially tapered at corresponding relatively steep angles to the spindle axis to have a wedge type bearing interengagement providing a self-adjusting friction drag braking action on the rotative movement of the reel that serves to prevent overrunning of the reel on stoppage of the feeding of the wire supply off the reel.

摘要： An automatic presettable welding system which enables the user to preset the arc voltage and wire feed speed to precise predetermined values without either energizing the wire with arc voltage or initiating the wire feed. A meter is supplied with an appropriate signal so the readout corresponds to the desired wire feed speed or the desired arc voltage and these same signals are supplied to wire feed speed or arc voltage comparative circuits which then function to energize a wire feed motor or an arc welding power source to the precise wire feed speed or arc voltage indicated on the meter. Means are provided for controlling the acceleration of the wire feed drive motor and a controlled initiation of the arc voltage at the beginning of each weld. Overload, over-voltage and under-voltage or over or under wire feed speed and other protective circuits are provided with appropriate delays in the functioning thereof to insure fully automatic and satisfactory welding.
