Anyone have a Lyman Mag 25 in 230 volt

[8shot]

Have a Lyman Mag 25 being shipped..not sure when it will arrive.

I want to run a dedicated 220 line in the meantime and was wondering which male connector it uses so I can set up the female junction box.

I don't have one, or know for sure, but it probably is the standard 20 amp 220 plug. It won,t use near 20 amps at 220 volts.

My Mag 25 is 110V. However, my Promelt is 220. The plug it uses is the standard one, that looks like a normal 110 but with one of the prongs running horizontal. Just like my Craftsman air compressor. If you need and extension cord, Home Depot carries them.

Lyman shows Euro or Australian plugs for 230, you will probably have to buy one. RCBS used to ship 230V without a plug.

Well the Lyman Mag 25 showed up today...already shipped back. The Lyman site lists it as 220 volt.

In reality it's a 230 volt "European" furnace which is not hertz compatible in the US (per Lyman techs). It arrived with the European plug.

Just learned that both the RCBS and Lyman big pot (220/230v) units are not compatible with the US hertz standard.

You really have to dig to learn this...just ordered the 110v.

Thanks for posting!

I wouldn't have thought Hertz would matter.

Your thought is correct.

Hertz is back and forth electrical cycles per second expressed in silly terms; we use 60 per second and others use 50. There are no restive (heat, incandescent lights) devices made and few inductive ones (motors, transformers) that care what cycles they are fed but they all care what the power line voltage is.

Any competent retail clerk selling electrical plugs and sockets can point out those made for 115 vs. 220 appliances. They're made different only to keep inattentive users from plugging 115 devices into a 220 line, few 115 things survive that kind of smoke test for very long.

I'm a retired space program electronics tech who does house wiring. I don't wire 220 circuits in homes unless it's actually needed to supply the load and that does not normally include American plug-in type appliances. A 220 line is just not needed or even helpful for small stuff and even our biggest home shop melting pots are small stuff!

One consideration is that a dedicated line (110v) might keep your pot working longer...power fluctuations (furnaces, electric stoves, water pumps, heaters etc) on shared 110 lines could affect the the pot's electronics' life. Another consideration is locating the lead furnace breaker as close to the entering power source on the bus as possible.

BTW: The Lyman Techs (not me) pointed out that the Hertz difference is detrimental by design to the lead furnace's electronics.

My Mag 25 works okay on 110

[pastera]

I seriously doubt the unit is not capable of 60hz operation. The only real question is the fan that they put in (is it an AC muffin fan or a cheap DC computer fan?)

They took the old unit, removed the mechanical thermostat and added a $20 chinese PID controller.

Good to hear was working with a Lee 10lb unit...even going to buy a sinker mold.

Worked a Lee 10 for years then RCBS Pro melt (sold it) then Lee 20 then Mag25 and RCBS Pro melt 2. Casted over 200,000 bullets over 30 years. They all worked: I just like new reloading or casting things. Kept all the pots but RCBS pro melt: guy offered me full retail for it could not turn him down.

The last PID I wired was 18-250V AC or DC and likely a 12V buss.

I second the idea that a 50 cycle fan is the delicate electronics that can't take 60 Hertz. LOL

PIDs have their own built in power supply and are not usually affected by line voltage fluctuations.

[Mike W1]

It's been a long time since electronics school so I can't argue with anyone but the PID is just turning voltage off or on so I'm inclined to think the Lyman tech was incorrect. An electric kitchen clock depends on Hertz to keep things in synch but the PID doesn't depend on it. Thinking the thought about the cooling fan COULD have some merit though.

To make a long story short..Lyman product #2800386 (230v Mag 25) is not for use in the US, if you use it...you void the warranty...so don't buy one. They don't make a 220v unit..even though their web page says it's a 220v.
