here's some of the machine and how hoses are hooked up

Oh--a welding test from 1960s ---

Here you can see front of the machine I use with this system

then close up of lower front panel which identifies whats behind the cover
Two red lines are the purge circuit I have plumbed thru the water valve
Yellow grd lead
small black hose argon gas out of valve to torch head
bigger black hose is argon supply from tank
power lug with water cooling line hooked to lead(the welding lead is copper cable inside a hose with water running thru it to torch head(cools cable and torch handle/head)

How do you like the Coolmate 3 Jerry???? Not sure I would ever be tiggin' enough to justify water cooled---or do I just not know what all the water cooling does?????

that why you just hook the torch up to main water tap . still be doing it but somone would shut off the valve or i for get the water was on then where was a mess on the shop floor or the line would freeze i like the smaller torch head with water when i inside welding a head ports

some more from around the welder---more pics of that FAA test and a can of solar flux Pat spoke about--
some of the various wires--steel, alum, stainless, inconel, titaniam

Help a rookie understand. What exactly is the water cooling?

start of a manifold about 1980????

Dave and Roger----water cooling allows a much smaller torch head for getting into some really tight corners--you can run 200+ amps thru a torch head about the size of a ball point pin

So the coolant flows through the torch, keeping it cool with higher power levels, yielding a smaller, more versitile torch? Super cool!!

I made my own water cooler, its only a pump and a reservoir, very easy really.

OK, thanks Jerry!!!! Well worth the extra $$$$$ then! Thanks!!

You will probably never need it Dave, Really comes into its own when welding for long periods or high amps on Aluminium. For tight areas use a Gas lens

I never do any welding in ports or anything, but I can certainly see where it would be nice to run one of the smaller torches!!!! Would make doing detail work and small pieces a lot easier to do with better resultz!!!!!

torch head is liquid cooled not water but you can use water must be flowing thru torch or or can burn it up. you have a in and out line and past 250 amps water get so hot i have melted the lines . the torch head with alcolol thru a cooler tower works abit better then just water

I added a couple edit comments about what was in the pics---
Dave--also some of the small torch heads you can twist around the shape and angle of the tip/nozzle
Romeo Palimedes have a straight inline torch that looked like a fountain pin--Miss seeing him---
I also have a on/off switch saddled to my torch to control the welder for like I'm twisted up inside a car doing a roll cage or such--too old to still be able to twist my leg around and step on the pedal---there is also one that has amp control-I think thats what Pat mentioned--I took it off as it sorta clicked when I pushed it and I would stick the tunsten--I think they have a rotary one now that that probably wouldn't happen with.

I use an antifreeze solution in mine---won't freeze and works good--sometimes the city water line would boil

intake yep welded up one in one day
