Miller Bluestar 2e

A digital aftermarket engine tach is easy to install. It's just a sensor wire that wraps around your spark plug wire. Then ground the unit to a chassis bolt somewhere.
Why do you need a digital amp/volt meter on this old welder? If you need more heat, turn the machine up. Less heat, turn the heat down. Doesn't get any simpler than that.

As far as the tach goes, I'd say pretty much any after market small engine tach/hour meter will work. It's pretty much a bolt on, modification free add-on.

I'd say it's certainly possible but really don't see the benefits. For most of the time there have been welding machines, they didn't have meters - it's a comparatively recent development.

Is it possible to add a Tac, Amp and a Volt meter to a Miller Bluestar 2E if so, should I do it? Would it be helpful?
