In one of your videos you mentioned getting insulation from a shop in otsego mn. After google searching I have not been able to find this shop. It would be great if you could share details.
I love the videos you put out. these videos made my life much easier. so I have a question. I'm looking to use a 1800w 48v ZVS, with 1/8" tubing. My questions is how many turns would you recommend if I'm turning the coils with an ID of 3/4". Either single wrap or double wrap. Thank you in advance for your help
Thank you for your kind words. I suggest that you examine this webpage of mine that deals with work coil design: spaco.org/Blacksmithing/ZVSInductionHeater/WorkCoilsForZVSInductionHeater.htm
@@frenchcreekvalley I watched your video and it helped me alot. See I am using the same exact 1800w heater @48v for my annealer. I will be annealing 6mmbr brass. I don't have the heater yet as it will be around 9/15/21 so I can measure the coil that comes with the heater to calculate a two turn coil, because I am limited on coil build OD due to the support that will hold the case. See I'm building an automated system that will auto feed, drop, anneal, then drop the case. My question is if I use shrink tubing to cover the copper tubing or class cloth sleeving, and water cool the tubing, do you think a dual layer 4 turn coil with a 5/8" ID work with my server power supply knowing the annealer will switch the heater of and on the desired amount of time to anneal my brass doing up to 100 pieces consecutively? Sorry for the long reply, as I wanted to give you as much info as possible to get the best possible outcome.
@@keeper1959fem Please examine this spreadsheet which shows results from many types of work coils that I have made: www.spaco.org/Blacksmithing/ZVSInductionHeater/Work Coil Data.xlsx Regular shrink tubing over the work coil will probably melt, but glass cloth (tubing) or ceramic tubing will be okay. You can see that I am only using the 1000 watt ZVS heater in this cartridge case annealing video. I would be a bit concerned that using such a small coil on the 1800 watt unit may cause overheating of the Mosfets due to low inductance and, therefore, high frequency of operation.
@@frenchcreekvalley Hello again, just an update. I figured out why the capacitors failed. one of them had a bad solder joint on the board, So your guess of defective caps was close. I should have it fixed in a couple days as I just received new ones. I did order a new ZVS and tested it to see my current draw. it ran at 12.5A while annealing. Thank you again
Hi Sir. I follow your Channel for a while, thank you for publishing. I want to know how are you calculating that Coils, I have the same ZVS machine and it came with an inconvenient size coil And need to make a new one. Canyou advise me? Greetings from Chile
To see my data on many different coil sizes, go to this webpage and then download the excel file about workcoil data: spaco.org/Blacksmithing/ZVSInductionHeater/WorkCoilsForZVSInductionHeater.htm There are several websites that have interactive formulae for calculating the inductance of coils. Here is one of them: electronbunker.ca/eb/InductanceCalcML.html
My interest is in cartridge case annealing (.223 & 30-06) and am interested in your work designing a coil to concentrate the energy to the shoulder and neck. I'd like to be able to use a lower voltage/wattage power supply. Obviously the small coil in this video heats too fast to be controllable on your setup. Would using this coil as opposed to the single layer coils most are using allow lower wattage PS? How does raising or lowering the inductance of the coil affect operation? Thanks
In two previous videos, I test work coils that don't heat nearly as fast as this one does. th-cam.com/video/CuzfCnK0E0c/w-d-xo.html th-cam.com/video/JVpOtdHeGUQ/w-d-xo.html If you use the same 1000 Watt ZVS type of heater that I use, your power supply must be able to deliver at least 20 amperes. But you can run at lower voltages than the 48 volts that I use here, but not, IMHO, below about 24 volts.
Just watched your video as you suggested, so here are my peramiters, so I'm hoping you may be able to give me some advice on a coil design. I have the same 1000w ZVS unit that is suppose to be rated at up to 48v. I will be annealing rifle casing as well designing a unit to anneal 6mmbr to 338 lapua mag. I will be using a relay to start stop the ZVS controlled by a time Here is what may be a problem. I purchased a power supply from a server that is rated at 48v @ 3000w. Yes a lot I know but for $78 I couldn't resist. Will this be an issue if I'm looking to anneal the smaller brass (6mm) in two seconds, using a two laayer coil with three wraps of 1/8" copper tubing with an ID of 7/8" of just large enough for the 338 lapua mag
great work!!! really impressive! I am building a 1000-1500W heater. are 2x 100Ampere IGBT good for that? or 2x 50A MOSFETs (want to drive them not too hot) and 1000V Capacitors (10x 0,47uF) (what voltage is good to not have them hot?)
The ZVS induction heaters that I use all use !RFP260N Mosfets. They work well with a 48 volt DC power supply. I water cool my work coil and fan cool the Mosfets and the capacitors. The 1000 watt model in this video uses two of those Mosfets. The 1800 watt model uses two PAIRS of the same Mosfet and the 2500 watt model uses three Pairs of them. I have not experimented with other Mosfets or with IGBT's so I can't comment on their use. In my experience, more capacitance equals more idle current and more heat in the capacitors that needs to be dissipated.
Hello i have VEVOR variac variable transformer,variable transformer 0-300V Adjustable,Output Volatage Single Phase Variable Transformer 1KW, Power Converter with Standard Plug Circuit Break can i use that for my induction heater
A "Variac", as I know it, simply varies the mains input, but the output is still alternating current. If your whole description is describing that variac, then, NO, you can not use it to power this kind of induction heater. You need a Direct Current power supply that can deliver at least 24 volts but not more than 48 volts DC, at 20 amperes or more.
