Ibought a hobart n 50 mixer took it oversaes used a 700 watt step down transformer to work it but after a few minutes it over heats is there a certain trans former to be used for it thank you
Assuming the mixer is overheating (and not the transformer), first check (with a multimeter) the voltage being supplied to the mixer from the transformer and ensure it is near 120V. Next, do you know the powerline frequency in the country you're in? The mixer (assuming it came from US) was designed for 60Hz US power. Many other countries use 50Hz, which could cause overheating if the mixer is used heavily. When 60Hz equipment is used on 50Hz power, it normally must be "derated" meaning it must be "underworked" as compared to its original capabilities.
Be sure to test the voltage going to the mixer, from the transformer, not only when the mixer is off, but be certain to test it in use, mixing whatever it is you are mixing -bottom line is to be sure the transformer continues to output 120V under load, with the mixer loading the transformer.
If all is OK with the power going to the mixer, then the problem is either in the mixer or the problem is how it is being used. What are you mixing with it - are you overworking the mixer? Does the mixer always overheat or only with particularly demanding jobs (cut down batch size in this case). What gear are you mixing in? If overheating in second gear, try mixing the same batch in first gear. If you have or can find a user's manual, it probably gives reccommended batch sizes for various typical products you might mix, be sure to follow these recommendations and "derate" for 50Hz if necessary.
It's possible the motor is weak from a long life spent working hard. A weak motor will draw excessive current and overheat. Where is the mixer hottest? The front at the gearbox/transmission or the rear where the motor is located? Maybe the transmission is lacking lubracation and needs a grease change. There a many possibilities for your mixer to overheat, and I hope this helps.
