U.S. Solid 15 KW 30-80 KHz High Frequency Induction Heater Furnace, Single Phase 220 V, 16:1 Turns Ratio

The best and the best comments people.

The machine wouldn't make more than a couple hours of use without water cooling lines leaking had to replace with better quality hose then after another couple hours the wayer cooled transformer started arking got with US Solids and all they want to do is tell me how to patch it haven't been able to buy replacement part from them so beware good machine at first but company is useless for replacement parts !!!!!!!!!!

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 YouUPDATE 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.)

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!

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 3/8x1" 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.

The media could not be loaded. Update:I have been going back and forth with US solid and the seller here on Amazon and they want me to try to repair the circuit board in the machine myself. I’m not a repair guy and for over 1k this machine should work as advertised and not die before it is 6 months old.I am very disappointed with this machine. I bought it and ran it once a week for three hours per session at most and six months later the whole thing does not work. I paid a professional electrician to wire it for the required power and always ran it with water coolant circulation. What a rip-off.Overall I would say the quality of the machine is poor.

Nothing but good results so far. Only weak element is the rather undersized foot pedal.
