Found out my forge temp was way off after 3 years of guessing
I was at a hammer-in last month and someone asked what color I run my forge at for welding. I said bright orange and they just stared at me. Turns out I was probably running 300-400 degrees too hot the whole time because I never actually calibrated my pyrometer. I used a thermocouple gauge from a buddy's shop and my readings were off by almost 200 degrees. Has anyone else realized their temp readings were garbage after checking?

That 200 degree error is actually pretty common with type K thermocouples once they oxidize a bit. I had the same thing happen with my kiln setup where I was reading 1900 when it was really more like 1700. It's worth checking your thermocouple with a multimeter's millivolt reading against a temp chart once a year to catch drift before it messes up your work.

Saw a thread once where a guy figured out his pyrometer was reading low by checking it against a known good one.
