- Brand: U.S. Solid
- Special Feature: Manual Thermostat
- Mounting Type: Floor Mount
- Burner type: Radiant
- Heat Output: 15 Kilowatts
- Heating Method radiant & infrared, Convection: Item Weight 70.5 Pounds
- Under the same conditions, our U.S. Solid Induction Heater Furnaces have the effect of saving twice as much power as conventional electron tube high frequency heating equipment, while reducing the electrical load and increasing the electrical capacity, saving you money.
- With a 100% full load design, our U.S. Solid Induction Heating Devices can operate continuously for twenty-four hours without interruption.
- Choose your machine based on power and frequency. The higher the frequency, the shallower the heating depth, and the lower the frequency, the better the heat transfer.
- Applications: small hardware heating purposes, tool welding, diamond tool welding, small parts heat treatment, a small amount of precious metals such as gold, silver, etc. melting, surface heat treatment, etc.

Excellent!

Got it a couple of days ago, came on time. Wired it up for my 220v plug easy. Used it for a couple of hours on and off, no more than 10 or so seconds at a time heating the ends of 3/8×1″ bar stock. Works great so far. Instructions are kind of crap but it is easy to use. If you don’t have a coolant system it isn’t hard to create your own with a few valves and some water pumps, just be sure to have a thermometer for measuring the water temp, preferably one you can set an alarm at a certain temperature just incase. Makes my projects go so much faster! I will update if I end up having any problems.

I finally got this thing wired up and hoses ran for the cooler. It works really well. I tried it with the stock coil and at first at the lowest power level and I heated the end of a bar up. On low power it took a while. I turned up the power and the metal turned red almost instantly. Seems to work well and I’ll update this if necessary

so far the unit has done everything i need easy to make coils and to operate .

This thing is awesome. I use it way more often than I thought I would. It’s able to heat steel up to 3/4″ or so for forging, very quickly. It’s much faster and more convenient than a gas or coal forge. It also easily melts small quantities of silver or bronze for casting. It’s much cleaner and nicer to work with than a gas furnace or large torch for casting a pound or two of metal.

It will only do 7 kW. Multiply input power by amps and you can quickly determine that 8.4 kW input means it is impossible to do 15 kW. Pure math and physics. Then I found in the companies own FAQ page where they admit this is only a 7 kW unit. I sent it back.

Item quit working after the 2nd time using it. No reply from manufacturer. Unfortunately out of the return window through Amazon.. Save yourself the hassle and buy a different brand

The mains power connection is not very safe needs an electrical box with strain relief for mains power cable. Also be able to purchase addition fittings for heat loop.

Instructions were awful, but after a knowledgeable friend helped out, it works fine.

I was worried when I first turned this unit on because it gave a “water lack” alarm even though I had a water pump that supposedly met the 2 gallons per minute at 43 PSI spec (converted from metric, of course). I ended up connecting it directly to the faucet and that silenced the alarm. If you go the water pump route don’t be cheap…you’ll spend at least $50 for the right pump on Amazon. People have pointed out that if you do the math on the voltage and current going into this unit it can’t actually be 15kW but that’s fine…it heated the 1/2″ square steel bar in the picture to that color (around 1500 degrees F) in less than 10 seconds! Very happy with this purchase!

US SOLID INDUCTION HEATER arrived in good condition box had been opened small Piece of tubing missing (adapter for diy coil) 1e mail later part is in route from supplier. hooked up water supply with an old car radiator 10 gallon Reservoir and recommended pump. hooked up power (50amp 220 volt) turned on switch and it heated a 1″ solid round bar to glowing hot(red)in less than 30 seconds tried a piece of 1″ conduit (thin walled) just for S/Gs 30seconds latter FIREWORKS conduit with timer set on 30 seconds blew out and melted this machine works just like you see on amazon. I heated two pieces of 3/16 x 1/4 inch high carbon steel to forging temperature in about 1 minute. put a 60mmx60mm crucible and turned on 15 seconds bright red top to bottom melted 1kg copper total time about three minutes +/- I have two of the ZVS 2500/3000 watt induction heaters from over the seas they are TOYS compared to this machine. OVERKILL?/ MAYBE DID I NEED IT/ NO! DID I WANT IT/ YES! HAPPY?/ OH YEA! my US Solid Induction Heater has exceeded my expectations by far Thank You UPDATE 5/2/22 part to make “extra” coil that was missing came in today

the 110v is wholly useless for most everyone. ( doesnt come with any plug at all, get you an exstension cord and just cut the female plug off so you can roll it about in the shop closer to anvil or forge press.)
