Sunkko 709AD Spot Welder Fail (110v Version)
#21
Just a heads up, I have the 220v version and while its got plenty of power for the job, mine gets warm after about 100 welds and it then trips my 16A RCD about once in every few welds. It works great again when it cools down over night say, but once it warms up again, the problem repeats. Completelycharged recommended I try it with a long extension lead to act as a buffer. I'll give it a go when I next have a few hundred welds to do.

Another thing you could do is add some fins to the transformer and put a big fan in there (or a larger one if there already is one there). The more air flow you have, the easier the transformer can work w/o overheating.
As far as the fins, you could just put a few aluminum heat sinks glued to it if there's space for it. But the fan alone might be good enough if it directly blows on the transformer

Check out this youtube video. It says the power to the external pen is much weaker than the  fixed electrodes.  The youtuber beefed up the current by soldering extra 10g copper wire.
