110VAC Heat Treat Oven

[Rob!]

Hey I know that guy. He makes wood stoves right?

Hope i Didn't say that wrong. It will work... It just will not work well.

It's just not good to leave blades in the heat for many hours. You can preheat the oven and save some of that problem - but it will lead to other problems for you - such as blowing up envelopes from sudden heat exposure - or long re-heat times after opening the door.

To be honest, mine could probably reach 1950 in a little over 3 hours - workable - but not desireable.

Your electrician friend should be helpful. Maybe you can run the wire and save him some time so all he's charging you for is good advice. I think you'll be happy you upgraded to 220.

Rob!

If you are in a situation you can run 220 to your shop quit talking and have the guy do it! While you're at it run at least 2 wires, 2 lines, yes copper's expensive but while the walls are open you might as well do it!
You can never have too many 20 amp 110 and 220 outlets in your shop, doesn't hurt to make one of those 220 lines 30 amp (that;s what my metal lathe requires. trust me. If you need to use extension cords within your shop other than to reach a hand tool with a 6 inch cord you do not have enough outlets

Just my opinion, I have 110 quad outlet boxes every 4 feet in my metal shop, and 4 quad boxes in the ceiling, and a 20 amp and a 30 amp 220 outlet in each wall

Rob - I'm not sure what was/is going on with your oven, but a 110V paragon, sugar creek, or any cone 10 kiln shouldn't take that long to get up to 1950. 110VAC is still AC electrcity just like 220 is, the only difference is that it takes half as many amps to get the same watts. If the oven can't reach a temp or hold it, it's probably too big or not insulated well enough.

To the OP - the 220V ovens are the way to go if you can afford them and you have a place to plug them in. If you can't/don't then 110V is fine, you're just limited in size. 90 minutes isn't too long to come up to temp and that's just for stainless steels, they tend to get get up to carbon steel range very quickly ~20 min. Most steels like to be ramped up to temp anyways so it doesn't bother me if things go a little slower.
