    Tig Welder Cart

    I upgraded the cart for my tig welder. This is not the compact inverter type welder with all the bells and whistles that I would like to own. It's a 1959 Miller 330 A/B/SP. It a copper wound transformer machine and weighs in at 850 pounds. It feeds on electrons and it would love to have a 100 amp circuit breaker to put out its rated 425 amps, but I only have it on a 50 amp breaker. Its lowest output is 3 amps. I paid $200 for it.
    I had it on a dolly made with angle iron and some heavy duty casters, but I wanted to have a handle up high to be able to move it around easier. Also there was no tank rack, so I built an extension to the dolly and a rack to hold the tanks.

    Here is the cart so far, with the dolly extension (3x3x1/4 angle with 1/4 plate for the floor), for the tanks and 1-1/2x1-1/2x1/4 angle for the corner uprights. some type of 2 inch wide channel for the diagonal braces and 1 inch pipe for the handle. A 1/4 x 1-1/4 flat at the top of the upright.

    Heat and beat seems to be the easiest way to do this.

    Now for the tank rack.

    Here are the first parts for the tank rack. I bent them on my hydraulic press.

    I drew this out full scale on a large paper so layed the parts right on the drawing to line them up.
    I would give anything for a couple of member SAS' clampable squares right now.
    (See sticky on the welding projects page for clampable squares)
    I taped framing squares to hold the 2 inch pipe.

    I put my oxygen bottle on to try the tank rack, I only have a 55 cu, ft. argon tank at this time but plan on getting a larger tank. I figured I might as well make it to hold two tanks while I was at it.

    Thank You Thurmond,

    The welder is a Miller 330A/B/SP Year 1959, Weight around 850# I don't know what the A&B stand for but I'm pretty sure the SP stands for spot weld because it has a spot weld timer on it.

    Primary Volts 230,460 - Amps 104,52 - Single phase, I have it on a 50 amp circuit breaker. I ran it about 120 amps and haven't tripped the breaker. It requires a 100 amp breaker for full output.

    Secondary Volts- AC 40 DC 30 Welding Range Inert Gas, 3-425 Amps in three ranges 3-50, 10-225, 175-425, variable in each range by front panel control or foot pedal.
    Duty Cycle 60% @ 300 amps, 35% @ 425 amps

    Has a start adjustment control
    Post flow timer
    Spot weld timer
    water and gas solenoids
    High Frequency, start or continuous
    Foot pedal RFC 23A

    Nice cart Nicholas! Very simple and clean. I'll have to see if I still have pics of the cart I built for my old Miller Dailarc welder. It was a bohemoth that held the Dialarc on the bottom, my big HTP Mig2400 above that, and my plasma on top. It was nice only having one cart in the shop that held everything -until you tried to roll the thing anywhere. It was like pushing a dead car around. I dismantled the cart and sold the welder. It seemed like a good idea at the time lol. The base for holding my bottles in the rear of the cart was flat with no frame around it though. The large cylinders were just too hard to lift so I needed the lift to be as low as possible. I chained them on top and bottom to prevent them from sliding off the tray. Now, if I had a fork lift like you have that wouldn't be an issue. Having a fork truck would be just plain awesome in more circumstances than I can list here. I'm jealous!

    Thanks James,
    That must have been one heavy duty cart. I like your idea about having a low to the floor plate for rolling the bottles on. Wish I would have thought of that. I think the biggest bottles I will have is about 125 cu.ft. and even those make me grunt.
    I always wanted a forklift and just so happened it came up for sale when I got my tax refund in. I like what you said "awesome in more circumstances than I can list here" That is definitely true. Don't know what I would do without it now.
