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.

Wire supply reel support device

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.
