Well, it freakin worked! A world first! Water-cooled stick welding stinger, powered by HTP America! :laugh: This is just the Beta version 0.9. Now that I know it works, gonna play around the the connections to make it solid. With only two tiny hoses (power hose and water return), it's light as a feather.




Hooked it up to the good ol' HTP Invertig 221. Eventually it will probably migrate to the Pro Pulse 300. The yellow sheath is a 1" ID kevlar sleeve. I'm probably gonna use another form of protection on top of that though.

Good idea.

The kevlar/aramid is massively tough as far as resistance to heat and cutting damage goes, but unfortunately it does suffer from degradation under UV exposure. Some outer sleeve material to work as a 'shade' would probably extend it's lifespan.

Bye, Arno.

I keep two stingers on short cords. I switch out the stinger and throw the hot one in a bucket of water..
Mines water cooled too!

But your cable isn't light as a feather.

Yeah number 2 wire ain’t lite.

I used my last vacation day to make v1.01 of the fitting.

Cutting a section of solid copper rectangular bar



Some basic milling

Fitting the 3/16" copper rod in the through-hole to make sure it is the correct size, not too big, not too small:


Silver soldered the water/power fittings and the plugs on the sides:






No Leaks:


Buttoned it up:



Can't say I'm crazy about this Tweco stinger, but I got it cheap like $15 on ebay, which is what I wanted because I didn't know before-hand if I would be modifying the stinger itself.
