Trailer for a diesel welder
« on: November 22, 2010, 02:59:19 PM »
My boss has been borrowing this gas powered welder for years from another shop to get field jobs done.  It was time to make one of our own.  He made the trailer before I got back to working with him, so no pics of the build.  I did get pics of the coupler we whipped up for it.

That is  a standard 3/8" craftsman  ratchet to show scale.  More pics just because you asked.  We used 1 inch and 3/4" stock welded with 7018 rods.

Is that a Lincoln Pipeliner welder under that tarp?

It is a 30 plus year old Lincoln with a hercules 4 cyl  motor.   I don't know the model.  It runs and welds decently yet.

He got the welder, It is a Lincoln with a 3 cyl GM diesel.  It is placed on the trailer but not yet bolted down.

And we discovered that with the weight of the welder on the trailer the tires and fenders had an issue.

So I fixed it.  Not near perfect welds but I can stand on the fender and it won't move.

And before the day ended I started to mount the tool box onto it.  There is a bit of work to do with this part yet.  More fabrication pics to come.

Strik you take my memories back almost 50 years with this build.

The first machine I owned was a Lincoln SA 200 I bought well used for $400- and managed to pay for the first month I owned it  by burning rod 16 hours a day.  8 of those were with my machine and it both burned and leaked oil, but 30 w oil was cheap back then.

I decided I wanted a trailer mount so I talked a truck wrecker into letting me cut the front X and frame off a Ford truck that had 16" tires, and went to scrounging up metal.  I ran around with that machine half built for a while till somebody gave me a bunch of 10ga cutoffs I could fill the frame in and make some toolboxes.  I learned a lot making it all cometogether, like how much easier it was to deal with the vibration if I was sitting on the machine welding rather than standing on the ground welding. 

You can get all the information and manuals for that machine from www.lincolnelectric.com since your nameplate is readable. 

Just one caution on closing it in, that machine needs to move a lot of air through the housing to keep the generator cool. 

A little sanding and some phosphoric acid treatment and you should be able to paint it right up nice, although painting a welding trailer should not be done until the rig is at least a year old.

We are trying to make it last our lifetimes and have resale value when its time to sell.  Heavy but not wacko heavy is just right.

I was doing some serious thinking on how to put the 90 degree bends in 3/16" plate for the bottom and back of the box.   :gaah:   It was so easy once I figured it out.  The shop has no sheet metal tools at all, I got almost perfect bends by hand!

Now I am going to make a hand box for me and post a build thread with pics.

Aw comon Rusty, you don't need a SledGoMatic for 3/16.   A good old fashioned fender wrench like towtrucks used to carry with modified jaws will get it done.  A young man should be able to wrench a 3" wide jaw with a 3 foot handle.  Of course if Strike managed to find one of them premium old large monkeywrenches and weld some bending jaws into it he owns the universal sheetmetal tool.

This post reminds me, I gotta go polish up my short handled 14 pounder or Merk will be flipping out.  He'd be upset anyhow that it isn't original and that I drilled through the head and installed a screw to keep the damn handle in place.

No banging instruments of any kind.  I ran the hand grinder down the line thinning the metal a bit.  Not enough to blue the steel but to leave a groove.  Clamped that into a heavy vise an pulled until I had the desired angle.  I think banged up metal in boxes looks like a hack did the work.  (I like to hide that !)

I know its not the same without pics  but when I build my steel plate toolbox it will be  :xFlash: documented and posted.

That's a very old trick for field bending aluminum in particular.

A router or a saw with carbide blades works well on aluminum.

We are trying for built to last without military armored vehicle specs.  And with what is laying around the shop to save material costs.  So far so good.

And the happiest thing of all, we started it and it runs good!  :spincl: I tried to get a pic but all look like the same.  About the time the camera flashed the smoke had cleared.....bummer.

Thank you sir,  my boss is very happy with the results also.  (That will get me paid  too.)
 The funny part is I mixed and sprayed the paint without a clue to base or ratio.  It covered first pass and very few runs.  I bet if I had a clue it would look even better.

The former owner of this has another, same model and year and now wants his done up too.  I kind of hope he makes the deal to do it.  I have practice now.

And now it has lights too.  He will get it plated soon to prevent any problems with the police.  A light retouch of the deck paint also.

Congratulations, now that you have it painted you have reached the point in welding trailer construction called Ya know what we shoulda put on there.

I always liked roll bars on machine trailers, you can mount and hang a lot on roll bars, from ladder racks to floodlights and of course flag sockets.  A running welder has a magnetic attraction for stupid steering wheel holders to not see it and run into it.  Even strobe lights can't protect a welding machine from forklift operators.

I like your reinforced deck corners.  Somebody recognized the corner of any trailer will get backed into any available nonmoving object.  Generally I like to put a skid from the corner of a trailer to the outer corner of the fender.  Skids save a lot of repairs to fenders since steeringwheel holders seem unable to pull trailers around stationary objects without the corner making contact.

You also need to put tank holders on there, propane, acetylene and oxygen and might as well put a spare on in case you ever want to carry argon as well. 

I've also come to the position it's a good idea to have some vertical and horizontal sockets on the corners as well so you can slip post mounted tools like vises and benders into and out of place.  Once you get to installing them throw a few extras on so you can jack the machine up and take the weight off the tires when it sits for a while. 

Given your location I don't suppose you need to consider snow, so a roof and sides probably won't be necessary.

Hey, paint grinds and burns off pretty easy, and you can always brush more on.

We are going to have to beef up the springs to put much more on this one.  He is going to have a custom tarp made to cover only the machine and leave the trailer open.  We can move it on the road covered in the rains to try to avoid those wonderful 80 volts at 200 amp reminders that welding and water don't mix.

I would like to see this trailer remain uncluttered and clean.  I think the boss is on the same page too.

Rather than beefing springs up, I suggest you look into airbags.

Firestone and a few others make a nice 5" diameter bag you can buy a pair of for under $100 and set them between the X and the frame with 3 bolts.  Believe me, bags beat hell out of springs, especially on something ov variable weight that will be going both on and off road.

As to a clean looking machine, that's real nice if it never leaves the yard, or if the repo man is looking for the machine.  Other than those 2 conditions, a machine should carry minimally 4 fire extinguishers, 2 being water cans, and at least 2 vises, one pipe and the other a 4" minimum standard vise.  A chainvise is damn handy for irregular objects too.  The one Buzzardbreath has been working on for 2 years now will carry his Bobcat, has a pair of toolboxes former electrical cabinets that are the deck frame, at least 6 electrical outlets wired to a plug so they can be powered either off the machine or from shorepower, and a 12 volt lighting system using LED heads that will light up inside the trailer box and the toolboxes.  He's presently debating lights under the deck so you can walk around the machine in the dark without tripping.  Under the deck is another storage locker between the framerails for additional cable and bars. 

The front of the box carrys a gas drive air compressor and a 3500 watt generator which didn't have anyplace else to live and will power up the trailer so the welder doesn't have to run when it isn't necessary.  There's also an electric winch to pull the Bobcat on and off, and there will be a removable crane on the back corner because old men don't lift.  When it is parked the trailer sits on steel legs so the tires don't develope flatspots.  The roof unit lifts on and off and the trailer tilts hydraulicly both to make loading and unloading the machine easy, and so the trailer can be more useful and serve additional purposes when the machine is removed.  It also carrys propane bottles for the infrared heater to keep the dumb weldor happy and a heating torch, and the normal O/A torch & bottles.

Definite yes on the under deck lighting! I've almost killed myself trying to walk around trailers after dark.

Cranes because old men are too smart to lift!

Truth is everybody here is in favor of the underdeck lighting concept, and with the LED units it becomes very possible and energy cheap.

We are however NOT admitting that because nobody has any damn idea how to make a 120 volt human detector [floodlight controll] function on 12 volts DC so the system operates from the on board battery the trailer has.  I know where there is a pile of those floodlight things that have been torn apart to see if they would work on 12 volts DC though.   Once that little problem is solved I know of a few trucks and trailers that will be set up with the system.  Meanwhile a number of residences & shops are being set up with LED emergency lighting systems.

We also found a LED unit for backup lights (19 leds) that only costs 4 bucks, so a good number of those will probably be going into toys as well.  One of the best parts of being retarded or is that retired is there is now time to play with some of the projects that were long shelved for want of time to make them happen.  It's also damn nice to look at the outdoor thermometer and say the hell with it, got indoor projects to play with.  Shoot, I've got a box of paper I sketched ideas out on and saved for this day.
