Picked up a new welder to add to the toolbox back in January - a Dynasty 280 DX. I wanted to make a nice cart for it, a 330 CF Bottle, and a custom DIY water cooler all in one package. It is not something I plan to load into the truck (heavy) but if I even need to be more mobile with it I will make a more compact version out of aluminum.

This was built using primarily 2" square tube 304L 7 gauge - it did not need to be this heavy at all, but I get access to a lot of drops from work, and some of the longer pieces I picked up on my own to complete it. The wheels and casters are from Tractor Supply. The welder tray angle is 30 degrees - a little more than I needed in hindsight but I am over 6 ft tall so the angle and height puts it at a good spot for my access & viewing.

I have a Marathon Electric AC motor, a Procon pump, and have an assortment of fittings, strainer, etc en route from McMaster to finish the plumbing. I plan to get fancy with it and plumb it with 1/2" stainless tubing. The reservoir is an 18" drop piece of 6" stainless tubing that I will cap, weld the appropriate bungs for supply/return/fill/drain/sight glass.

I picked up an appropriate connector to wire the electric motor to receive power from the CPS port on the Dynasty rear (looks like a PC power supply type connector).

I will update pictures as I finish the project.

 

Dang, that's a bit large eh? I am interested in how you are going to finish it off and utilize all that extra space. What size tanks do you plan on running? Holy ****, I didn't realize they finally released the 280!!! ********!!! I had my order in on one a few years ago and it kept getting put on back order and then they dropped it like it never existed. It was even in all their catalogs LOL... Looks like I am going to have to hit YouTube up for some videos!

 

Nice work. Super clean. keep up the good work!

 

Clean!

 

Looks twice as big as it needs to be?

 

Some further additions to the cart.

 

dammmn dude that is freaking work of art lol

 

Looks very nice!

Couple of questions though.

1) How did you bend the steel tubing? I can bend small diameter SS tubing just fine with various benders, but when I step up to 3/8 and 1/2" it all goes to hell. I can do AL/Copper just fine though.

2) How exactly does your water cooler function? I see a pump (which by the way looks ridiculously oversized) and the water reservoir, but I do not see a heat exchanger anywhere?

 

A tubing bender designed for stainless tubing. Similar in design as the cheaper ones for aluminum or copper, but built better and with longer handles.

As for the pump, it is a standard procon pump that miller and Bernard use - the coupled electric motor is no different than the one in the miller coolmate 4.

Currently no heat exchanger. With a 2 gallon capacity, and the amount of welding I do I may not need one right away but I do have a thermometer in the reservoir to see how it performs. I will likely install a bar and plate cooler (transmission/oil cooler type) at some point between the pump discharge and torch connection.
