WELDING ARC STABILIZATION PROCESS
First Claim
Patent Images
1. A method of generating a welding arc comprising the steps of:
- initiating wire feed speed;
temporarily reducing wire feed speed for a period of time based on detection of arc initialization and a user selected speed; and
adjusting wire feed speed based on the user selected speed.

Abstract
A system and method for stabilizing a welding arc is disclosed. The method of initiating the arc includes the steps of defining a wire feed speed based on a user selected wire feed speed and then abruptly reducing the wire feed speed before the wire feed speed reaches a relatively stabilized speed for welding, thereby allowing a welding arc to initiate and propagate to a generally steady state.

15. A welding system comprising:
-
a power source configured to generate a power signal suitable for welding;
a wire feeder connected to the power source and configured to deliver a consumable wire electrode to a weld at a wire feed speed; and
a controller connected to the wire feeder and configured to automatically set a rate of acceleration of the wire feed speed, then, while maintaining a direction of wire feed, abruptly reduce the wire feed speed before welding arc stabilization and then set the wire feed speed to a relatively stable speed for welding. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A welding system comprising:
-
a power source configured to generate a power signal suitable for welding-type applications;
a wire feeder constructed to deliver a filler material to a weld; and
means for controlling a filler material delivery rate that reduces the delivery rate without reversing a delivery direction based on welding arc initialization prior to arc stabilization. - View Dependent Claims (26, 27, 28)
