what kind of welder are you using?
what welding process?
got a plan of what you are making?
IPM is inches / minute. that's how fast the wire runs/how many amps its using. price isn't based on that.
AFA IPM goes, if you can do it in spray and you're up for production welding... 600-700ipm is common for .35 wire in production.
Figure your cost/lbs of consumeables and depending on what process you are running you can find out the transfer rate of the metal into the weld. With the IPM of the process you can add 15-20% of that and get how much gas you're running.
There's the majority of your consumeable cost, not factoring machine wear.
Now find your labor. IPM is the actual "arc on" time. Figure double that for work time. x5 for production time (if you are making & cutting - torch time/consumeable is figured the same as arc time)
For general wire welding... $9-18/h depending on where you are and how good you are at wire welding. The vast majority of general stuff falling between 9-13/h for non-specialty wire work.
