Same Einhell welder, just added a 120mm mains fan to the rear, using the existing 4 holes and grille there already, but not installed by the manufacturer. Blows across the transformer, and with the duty cycle now being weld a rod, wait a minute, then weld another rod, perfect for my use. Only drawback is that when welding the extra stray magnetic field tends to stall the fan at high current, but it will carry on again when unloaded, or at low current. Never bothered to put in any power factor correction, but did add a single diode on a heatsink , connected to a 40A thermal breaker added to the front panel, and a 4mm output, so that I can use it as a battery booster, being able to get a car battery from flat to able to start a vehicle in under 1 minute.

As mentioned theres a very simple DIAC application, used in nearly all vacuum cleaner and so on and theres a lot of integrated Triac controllers. Thyristors/Triacs are complicated to handle. They sometimes might not fire (especially if nearly 100% duty and while used on brushed motors) so you need to re-fire them. This integrated controllers do this very well. Here theres no software required at all.

Personally, I really enjoy the practical (Mechanical and restoration) projects you do, But I often become lost when you jump into the circuit descriptions and theory. I think it's important that you still include them though, because it's going to be useful for people who want to understand exactly WHY something works, rather than just copying a circuit that you've already thought out without them understanding how it does what it does. I remember watching your video about how a magnetic shunt works in a welding transformer, and dispite not understanding everything you talked about, I still think I now have a much better understanding of the principles behind it than I had before watching that. So thanks for making me ever so slightly less of an idiot. :D

Mounted a full diode bridge 90A in my old transformer AC flux core welder. Made the welding much less sputtering and capable of welding thinner gauge. Recently got a Lidl 100 EUR flux core welder and it is so much better. No wire speed adjustment because it does it itself based on current draw and it looks like tig welds, welded a thin gauge tube on the side of an oil barrel and it holds water and that was on 0,6 mm gauge soft steel.
@RandomHacks3 жыл бұрын
Altough the circuit with the potentiometer seems a lot more practical than turning the original current control knob a million times, isn't it a lot harsher to the mains network as you are enabling the triac mid wave resulting in a big spike of current? I did actually use a similar circuit before with the zero cross detection and time delay for a heater but I rapidly changed it as soon as I noticed the flicker it was causing to the lights, in my case since it was a heater it was easy to solve, I just used an opto triac with internal zero cross detection and used time proportional PID (which results in like a slow PWM with 200ms period) to control the temperature but this of course wouldn't really work for a welder or atleast it would result in terrible welds I think. Keep up with your videos I really enjoy them!

A person isn't capable of putting out all the much power, so it is usually not practical to create one. There would need to be other reasons than getting power to justify it in most cases. I have seen practical uses in developing countries for charging cell phones, and tiny battery powered lights. A single solar panel would cost about the same and provide much more output though. If you like I can get you an equation for human output over time. Obviously it varies from person to person, but studies have been done to get an average.

Oh yeah...this was the first thing i did with this cheap Einhell welder... Right out of the box, even without trying it as it is, i added a fan at the back (from an microwave oven...230 volts) and changed the welding leads for longer once with higher cross section... Now it is nearly impossible to trigger the overheat fuse in practical use. (unless you are a professional pipe welder or so.... xD) I did the same on my cheap flux core welder. There i also added a extra power supply for the feed mechanism to make the welding performance smoother. All in all, very cheap and easy to make upgrades on such low budget machines....
