Even if the torch is water-cooled it is first and foremost gas-cold (or argon or helium).
The business-end is gas-cooled just like a gas-cooled torch. Bit it is not enough on
these small water-cooled torches so the water needs to cool what the gas leaves behind.
In the getto-cooler the returning water is easily accessible. Checking the temp on
the return-water I notice, just like in the video, that there is not a whole
lot of temperature increase.
Doing the math one can see that the cooling power isn't very high. Under longer periods
of welding one can see, just like in the video, that the amount of energy transferred from
the torch to the bucket isn't a lot. Again the cooling power can be calculated, and it
is not a lot. It is so little that a big bucket of water can be a good reservoir and may not
need forced cooling to transmit the increase of the water temp to the ambient air.
I think we’ve done this to death...
The whole world of welding manufacturers must be wrong and should immediately switch to pond pumps as Rustwelder has done some extensive testing on YouTube and in his shed.
I will speak to the engineers in Göteberg tomorrow and suggest they watch “The Fabricators” videos, because a guy building car parts in his garage, who has to post a video a week to earn his living, with no formal welding training is obviously more qualified than chartered engineers.
