In this video I hooked up a Weldtec water cooler to my Dynasty 280dx tig welder.
I’ve been meaning to get this done for quite a while because using a 150 amp air cooled torch on a 280 amp welder is limiting
I recently got the expansion card that will allow me to use all types of amplitude settings on AC and I want to be able to explore all the capabilities of the machine when it comes to thicker aluminum.
Why WeldTec?
Right before I retired from Delta TechOps, we hooked up several Weldtec Water Coolers to some new Dynasty 200 tig welders being set up to weld engine parts.
We tried using a different compact tig cooler but they were too loud.
When you are in a small space, you really notice continuous noise from a cooler.
The Dynastys were quiet with the “fan on demand” feature so the extra cooler noise seemed unecessary.
The Weldtec is pretty quiet compared to others I have used like miller, Dynaflux, and Everlast.
That was in 2010 and they are still running fine as I write this here in July of 2019.
That is the main reason I chose to go with Weldtec.
A few more reasons:
- If I ever need to upgrade to a higher amperage cooler, I can just order a larger tank and replace the smaller one.
- It’s easy to order replacement parts from Weldtec.
- Its stainless steel so rust isn’t an issue.

SW320 speedway torch
There are several different styles of water cooled torches.
I have always preferred the #20 style because of its versatility.
The SW320 torch is rated for 320 amps and my Dynasty 280 will never exceed that
The feel of the SW320 torch is nice as well because of the contoured handle.
It provides more control on small tubing where rotating the torch handle is needed to maintain torch angle.
Dinse Adapter
Most newer inverter tig welders require a dinse adapter in order to hook up a tig cooler.
It would be great if one dinse adapter worked for all machines.
Sadly, thats just not the case
Some machines have a gas thru style dinse so its important to identify which style dinse your machine needs before hooking up a water cooler..
Once you identify which dinse adapter you need for your machine, hooking up your water cooler is pretty simple if you follow the instructions.
It is possible, however, to connect the dinse backwards so be mindful of that during installation.
The main thing to remember is that the water or coolant needs to reach the torch head first before the power cable.
