i have the same model DH30 from BIFRC. i can get good welds on 0.12mm nickel strips using power #10.. just use a very light pressure on the tips or else your welds wont stick.

That beeper definitely needs an application of hot glue to the sound hole! Thanks for the review,

Great video. Thank you

Friend, I had a bifrc dh30. I went to recharge it with a Type-C cable that I made myself but unfortunately I made the connections reversed in the Type C jack and ended up burning the sop-8 pin IC "IP5306" (that you point with the pen at 12 minutes into the video). The bottom part at the exact point where this component is welded ended up carbonizing and also part of the tracks, as well as the IC itself. I'm an idiot I know. I'm going to buy a DH30 Max, but I would like to use the DH30 board for something (mosfets and eventually some spare parts in the future for the new dh30 max, if necessary). Would you know if the mosfets are compatible between these devices? Thank you very much.

do you recommend the dh30? looking for a spot welder to make myself a few fpv drone li-ion battery packs

I am on a lookout for a fine adjustable spot welder for doing sensitive electronics. The idea is to adjust for minimum exposure time / minimum amps so that the weld between the nickel strip and the 389 Renata button cell battery is just good enough to keep them together, without frying the electronics behind the nickel strip. Is there some spot welding guide that says exactly what settings would be safe for application like this?

Good afternoon, master Please provide a schematic diagram Lambda LQ-521 of the power supply! Thank you, sir !!! Please !!!

hey what are your views regarding this Mini Spot Welder? Do you recommend to buy it? Is it good for long term use?

Try to welding 0.3mm nickel strip. coz I have cheapest BIFRC that can welding firmly at 0.3mm.

Any idea of the exact battery type used in this spot welder?

Thanks for the review :-)

Late to the party but you're pressing very firm on the electrodes. While this is intuitive it's actually reducing the weld strength. The heat comes from the resistance, so just make sure to have good contact but don't press hard.

I bougt this dh30 and inside is little difference. In my is different mosfets and different uC. And my cant weld anything. Doesent have enaught power.

mine stuck on beeping the power on sound and it is not closing up. It continues this sound, anyway to reset it ??? i used only 4 times, ver very poor quality

I hate your videos - I usually end up buying what you show. First DMM, then DMM with oscilloscope, what now? ;-) Great job brother!

Nice job. I think the fact that you were able to peel the nickel strip off the battery demonstrates that the welds were unsuccessful. The metals did not fuse. What if you put one tip on the battery terminal and the other on the nickel strip? That should ensure that all the energy goes through contact point(s) rather than bypassing the junction through the nickel strip.

How can I contact you? Please, master, I can send you your e-mail !!!
