To accurately measure wire-feed ipm, snip off the wire at the contact tube. Squeeze the trigger for 6 seconds; release and snip off the wire electrode. Measure the number of inches of wire that was fed out in the 6 seconds. Now using basic shop math, multiply its total length in inches by 10. The result is how many inches of wire were fed per minute.
