Hi All,

Can someone explain to me in layman's terms the advantage of using something like the PUK 4 welding machine by Lampert?

I've been looking at the demonstration videos and Im a bit perplexed to be honest. I can understand the 'filling porosity' application, but does it differ from soldering that much ( I.E. do you still need to solder over welds? )

Im also assuming that it doesn't generate heat like soldering does so guess theres no issues regarding fire scale or being ultra careful around gems etc?

Sorry for the daft questions, but looks like an incredible piece of equipment, albeit very expensive and puzzling!
