An arc welder including an integrated monitor is disclosed. The monitor is capable of monitoring variables during a welding process and weighting the variables accordingly, quantifying overall quality of a weld, obtaining and using data indicative of a good weld, improving production and quality control for an automated welding process, teaching proper welding techniques, identifying cost savings for a welding process, and deriving optimal welding settings to be used as pre-sets for different welding processes or applications.

1. A method of training an operator to perform an arc welding process by providing feedback to said operator during said arc welding process, said method comprising: (a) monitoring an electric arc welder associated with said operator, as said electric arc welder is used by said operator to perform said arc welding process by creating actual welding parameters between an advancing wire and a workpiece with said arc welding process controlled by command signals to a power supply of said electric arc welder;(b) during formation of a weld by said operator according to said arc welding process, periodically generating a numerical score indicating a current quality measurement of said weld, each numerical score generated by: (b1) generating a series of rapidly repeating wave shapes, each wave shape constituting a weld cycle with a cycle time;(b2) dividing said wave shapes into states;(b3) measuring a selected weld parameter occurring in one of said states at an interrogation rate over a period of time to obtain a data set for said selected weld parameter;(b4) for each period of time, calculating a quality value for said selected weld parameter from said data set;(b5) comparing each quality value to an expected quality value to determine if a difference between said quality value and said expected quality value exceeds a predetermined threshold;(b6) if said difference exceeds said threshold, weighting said quality value with a magnitude weight based on said difference, and weighting said quality value with a time contribution weight based on a time contribution of said state to its wave shape; and(b7) using said quality values, including any weighted quality values, obtained during said arc welding process to determine said numerical score; and(c) comparing said current quality measurement to a predetermined threshold weld score, wherein: (c1) if said current quality measurement is greater than or equal to said predetermined threshold weld score, indicating to said operator that performance of said arc welding process by said operator is satisfactory; and(c2) if said current quality measurement is less than said predetermined threshold weld score, indicating to said operator that performance of said arc welding process by said operator is unsatisfactory. 2. The method of claim 1, wherein the indication in step (c) is provided to said operator visually. 3. The method of claim 2, wherein the indication in step (c) is displayed on protective headgear worn by said operator. 4. The method of claim 1, wherein the indication in step (c) is provided to said operator audibly. 5. The method of claim 4, wherein the indication in step (c) is output to a speaker in protective headgear worn by said operator. 6. The method of claim 1, wherein said numerical score generated in step (b) is an instantaneous measurement. 7. The method of claim 1, wherein said numerical score generated in step (b) is based on a plurality of measurements taken over a period of time. 8. The method of claim 1, further comprising (d) suggesting corrective action to said operator if performance of said arc welding process by said operator is determined to be unsatisfactory in step (c2). 9. The method of claim 8, wherein said corrective action is provided to said operator in real time during said arc welding process. 10. The method of claim 8, wherein said corrective action is provided to said operator visually. 11. The method of claim 10, wherein said corrective action is displayed on protective headgear worn by said operator. 12. The method of claim 8, wherein said corrective action is provided to said operator audibly. 13. The method of claim 12, wherein said corrective action is output to a speaker in protective headgear worn by said operator. 14. A method of training an operator to perform an arc welding process by providing feedback to said operator during said arc welding process, said method comprising: (a) monitoring an electric arc welder associated with said operator, as said electric arc welder is used by said operator to perform said arc welding process by creating actual welding parameters between an advancing wire and a workpiece with said arc welding process controlled by command signals to a power supply of said electric arc welder;(b) during formation of a weld by said operator according to said arc welding process, periodically generating a numerical score indicating a current quality measurement of said weld; and(c) comparing said current quality measurement to a predetermined threshold weld score, wherein: (c1) if said current quality measurement is greater than or equal to said predetermined threshold weld score, indicating to said operator that performance of said arc welding process by said operator is satisfactory; and(c2) if said current quality measurement is less than said predetermined threshold weld score, indicating to said operator that performance of said arc welding process by said operator is unsatisfactory; and(d) suggesting corrective action to said operator if performance of said arc welding process by said operator is determined to be unsatisfactory in step (c2),wherein said corrective action is determined based on input from one or more sensors associated with at least one of said operator and said electric arc welder including its surrounding environment.
