People ask me what welder i use on my packs. This is her.
It’s a Sunkko 788H I got from a dude in Chicago over ebay and its been the shit for about a year now. I also own a 709A but i feel like the 788H works better on the heavier nickels.
So far i’ve been able to do both 0.15mm as well as 0.2mm in pure nickel when i crank it way up.
Anyone else building packs with one of these and what are your thoughts? Got any mods to share?
