This series of photos shows the portable rig for my Maxstar 200DX. The cart is made from Aluminum because I wanted light weight, especially when having to get it up a flight of stairs. There are stair skids on the backside, like a handtruck, made from High Density Poly-ethylene plastic so it won't leave any marks on the stair treads.

The axle for the big wheels is behind the center of gravity of the tank, so even if the tub and welder are removed from the cart, it won't flip over backwards. The tube frame extends under the base plate for strengh. There are 2 tiny high quality casters under the base plate edge so the rig can be rolled around while upright.

The Tub is a Klein Tools tool tub, with nesting trays for parts and tools. For travel everything fits in the tub including eletrical wiring tools and a small tungsten grinder. I used a 14L20 4-pin twist lock connector for the machine. This way I can use premade 10-4 extension cords that are made for connecting to generators. I have 3 of these at 25 feet each. I have a pile of adapters made up with the same connector so I can hook up the machine to any connector I run into or hardwire it into a panel, hence the electrical tools and testers. I can use the adapters with or without the extension cords.

The torch is a CK Worldwide 210 Trimline, 25 foot cable, with a very small contactor remote switch taped to it. I use exclusively #4 series gas lens collet bodies and collets from CK for this torch since they make for a much more compact torch. My main torch now is a CK100, which suits the stainless sheet metal work I am most often doing and is a much more comfortable torch for small work sicne it uses #2 series parts. Both torches have CK clamshell adapters to split out the gas from the power for the machine.

I made a compact foot pedal but have yet to need it since the sequencer is activated by the remote switch and is usually more convenient to use.

I also have a small tackle box for all the torch parts and tungstens.

You will notice that the machine is fitted with Western Enterprises quick disconnects. It makes it that much faster to assemble and disassemble the machine. The flow gauge I use has a hand wheel nut on it so no wrench is needed.

The armor for the machine is a simple piece of 1/8" thick aluminum sheet bent into a channel and lined with foam pads. The armor extends far enough to protect the quick disconnect gas fittings from harm during transport. I used a 64 cu.ft. argon tank to save weight and height.

This rig has traveled all over the greater Seattle area and has proved to be very useful.
