what size welding tanks on service truck?

[elvis]

We have a couple 20# aluminum co2 bottles that have an argon valve and filled with c25 for portable stuff. Pretty handy. Just swap them at airgas just like I do with my beer co2(5#-20# tanks). I believe the 20# tanks are rated for 60ft3 of argon/co2 mix. They are nice and light and very portable. They don't last that long though.

Depends a lot on your location, and your LWS. Just checked with mine today, they exchange ownership cylinders down to 80 cf. They do on occasion send in smaller oxygen cylinders, for refilling and sending back to the customer. Guy wasn't sure about small shielding gas cylinders. I will check with Airgas and see if they can do it, either filling or exchanging.

Tractor Supply and others are selling them, somebody's got to be filling them.

Sure my LWS would send them in to fill them if I wanted to wait 5 days...or whatever it is...but why would I.
True I have a co2 bottle for a kegerator that needs to be "filled" and not exchanged, but we were talking shielding I think...?

Here is chart with dimensions and weights which may help.

What Portable says here is valid. Based on my own experience, you should have a #4 acetylene (standard size), either one or two 125 or so Cubic foot Oxygens. Bigger is better, but you don't have a big enough truck. Having two smaller tanks allows you to go out with an almost empty, and switch over if necessary to a full.

I would look into buying some small shielding gas tanks, 20 or 40 cu. ft. capacity. You probably won't be able to exchange them, like you can with normal tanks, have to send each one in to be refilled, and wait a week or so to get it back. Buy two of each, one is out and one is on your truck. Big advantage, cuts the weight you are carrying way down. Leaves more capacity for carrying tools, parts, and metal, which may be more important.

I exchange my small tanks that I bought/own just the same as the ones you rent. I don't "send them in to be filled." I have what must be a "U-40" and a "Q"... FYI

And. What's the pipe frame rig welders have behind their welders does it have a purpose or is it just to keep the welder from getting banged up.

Its called a Hoosier pole and the above definition by JSFAB is spot on.

It really depends on the work you do, How much you use your gas at a given time, How close your work area is to your gas supplier, Are you going to be using big rose buds Etc., Do you have room on your truck and weight capacity to carry big tanks.

If you only go through a couple tanks a year then go small, If you go through the gas in a week then go big.

My local norco has a loading dock I just back up to. No heavy lifting I just roll them off

I own. A 97 dodge ram 3500. I work on tractor trailers on the side of the road. Most my work comes from truckers broken down.

large oxygen. medium actylene

And. What's the pipe frame rig welders have behind their welders does it have a purpose or is it just to keep the welder from getting banged up.

Large oxy, med actylene, all cylinders go into a locked cabinet, but i have a mechanics truck. Actually got a new one this year. Fyi, dot rules are for all cylinders to be capped during transportation, although i have never seen them check. All shielding gas is medium size cylinders.

More information needed. What kind of work are you doing??? What kind of truck (weight capacity) do you have? How strong is your back, or do you have a forklift or loader tractor that you can use to remove and install bottles with?

About the frame on pipewelder trucks, mostly just to support an arm or boom to hang out over the pipe, holds the cables and cords and hoses so you don't drive over them. I do mostly equipment repair, and installation in industrial facilities, don't have a need for this. If I am wrong, anybody in the business, feel free to correct me.

Also some pictures would help. I've done a lot of searching on the web for setups and designs.
