I would think that breaker is fine...What else is using that circuit? How many amps draw does the machine manual (or tag) say it requires? Is this just at full power, or all settings? Are you using an extension cord (if so, how long, and what gauge wire)? Tell us more!

it says imput current @ rated output 20Amps. imput power 120/1/60
nothing else on circuit i think and its at full machine power but it was tripping the same at 75% power. was welding a metal rod to a flat piece. putting wheels on a engine houst. my old house never tripped a circuit so i never paid attention
