TA-0417: VEVOR 737G Spot Welder - Hands On - Teardown - SUNKKO

Thank you Tony for the review and look inside. I own a large Vevor ultrasonic cleaner for cleaning circuit boards. It also seem to be well made and does a great job. Regards, David

Thank for Information. I heave the Sunko 788H spot Welder with Lithium Cell Power Supply.
Danger! The Remote Control High Voltage!

Interesting device. Thanks for the excellent review Tony!

Would love to see peak amps on the output with a clamp meter :)

Hey Tony! Altijd handig zo'n puntlasapparaat. Ga je accupacks produceren of was het alleen voor de demo?

It looks like a great unit but it looks like it needs a way to fix it to the bench as it was lifting while you were welding using pressure.

Lol! Such a big box, such a miniature transformer. Lol, pretends to need a 40A breaker? Seriously one can get a microwave transformer for nothing, replace the HV windings with some thick braid and use a 555 timer with total costs under 10 bucks. Now see how many different inrush amps readings you get using 50 different meters. Maybe they also sell a Vevor meter tuned to show them 888 Amps?

Hi Tony, nice welder which is clealy very substantial. I purchased a Variac from Vevor 4 years ago. They delivered it to the UK in just 3 days and the price was really good. Thanks for sharing Tony. Regards Ian

Hi Tony, I’m pleased to see that we’re using similar tools. I’ve been using this one for assembling batteries for more than a year now. It is a reliable machine despite that I would have loved to use pure nickel strip instead of alloy but this tool is struggling a bit with it. Also I prefer to use the pedal as sometimes I loose control when adding too much force to the lever and the whole thing starts to move up and jump making sparks and short circuits. Otherwise great video thank you!
