Hey Guys,
I've been using my Sunkko 788+ for about a year now with 0.1mm nickel plated (steel) strips and I used barely half the power of the thing and the welds are super strong.
Just got my 0.15mm pure nickel strip (tested it to be pure nickel also using some testing guides from google) and even in the highest setting the tab can be pulled with medium force.
The highest setting makes the tab red around the weld area for a second, meaning that it gets hot as hell but still doesn't connect well.
The biggest problem is nickel to nickel (when connecting cells in series), while trying to weld pure nickel strip on top of another nickel strip it doesn't connect at all even at the highest setting that gets the tab red hot!
* I'm using double pulse btw, which is the highest pulse number my machine has.
I was reading the description of the Sunkko 709A on eBay and it said that it can weld up to 0.3mm and if it's pure nickel then up to 0.15mm which makes sense.
The thing is, since my Sunkko 788 got the tab red hot and still didn't connect, will the 709A have any potential of working with pure nickel as advertised?
The only reason it MAY work is because it has up to 8 pulses which mine has only 2 but again, mine got the tab red hot and didn't connect so will more pulses work for me?
Thanks,
Roy
