A WPS allows minor changes in the welding voltage and amperage. True or false

A WPS is written with defined ranges and tolerances for process variables, not as a single fixed setting. This lets you make small adjustments to voltage and amperage to accommodate real-world conditions—like power supply fluctuations, wire diameter, or fit-up—without invalidating the procedure. The weld remains within the validated process window as long as those changes stay within the tolerances specified in the WPS. If you need to go beyond those allowances, you’d need a revised WPS or requalification. Hence, the statement is true.
