Is it safe to use lead solder on the circuitry of a deep fryer.? This is not in the part that contacts food, but just the inner wiring. ---

solder is a mix of tin and lead. typically 60/40 I can’t see any problem. The original connections were soldered at the factory. there are sliver solders available for plumbing. Costs $17 a roll I’m not sure if it works with electrical wiring. > **[Oatey Safe Flo 8 oz.

sure. unless the fryer catches on fire then it’s not going get hot enough to remelt the solder. don’t use plumbing solder or acid core solder on electrical connections. ---

I’d suggest using a flux cleaner afterward. There are a lot of brands and a can lasts awhile. [http://ep.yimg.com/ay/yhst-11111665262165/flux-remover-cleaner-4.jpg](http://ep.yimg.com/ay/yhst-11111665262165/flux-remover-cleaner-4.jpg) ---

Why are you asking? Are you asking a question about toxicity or temperature or electrical repair or what? ---

Use rosin core solder. For electronics or electrical. ---

As long as its not in a location that gets especially hot, I think you’d be OK. Personally I’d be a little nervous using lead solder in food preparation equipment, since even the fumes are pretty nasty, but if it’s around the circuit board or another place that doesn’t get hot you should be OK. ---

How many amps will the soldered joint(s) be carrying? Solder really isn’t good for high-current applications - I’ve seen soldered joints get so hot that the solder melted out. If you’re looking to solder sensing and control wiring, you’ll be OK, but the connections to the heating element(s) are more likely mechanically crimped or brazed. ---

though in the old days house wiring joints were soldered. i’ve taken apart those joints where the solder joint was in better shape than the wire. those joints were done by experienced professionals with professional equipment. it’s true that in modern appliances the heavy current wiring is not likely soldered.
