Hey. I am looking into getting some welder for building them battery packs, for some reason i found this sunkko welders, and thought maybe it's a smart idea to get the model that comes with both a soldering tool and a handheld spotwelding pen.
but here is the thing, i saw a video of someone using the 709A welding pen on a 120V outlet somewhere in the states, and that welding pen didn't perform well at all, but i don't find any good video or tests vs the A and the AD version, so is there someone out there that knows which one to get? I live in europe and we run 230V at home.
I am looking more into using the welding pen, to me it seems like u have more control then, and if you build a big battery pack i don't think holding each weld point up to the machine is going to be very viable when u work with a 1-2kg battery pack.
which one should i get and why in your opinion
