FNIRSI® SWM-20 1200A Dual-Pulse 2-in-1 Portable Battery Spot Welder

Good quality products

I now own a few items from FNRSI and they are all well made and work very well for their price range. The spot welder works really well but would have been nice if it game with some example settings for different situations.

Surprisingly powerful welder

It deserves 5 stars, but the charge icon never shows when the charge is finished, even after 24 hour of charging, when battery is actually full and charged. Maybe this can be fixed with the firmware update. Regarding spot welding it allows warmup, regulate tack in mil-seconds, and set the number of consecutive welds. Works very well.

I appreciate the quality of your product and the packaging

I like the way that most of the products that I receive from Fnirsi are made, the interface is very simple and the product looks professional and delivers accurate results. The welds are very consistent too.
