My on-board welder project(The Hillbuilt)

Coppertop · 10-11-2009, 01:13 AM

Since I started wheeling theres always been a desire to carry everything a person needs to get off the trail. Including a on-board welder ,after checking the price of a store bought one .Well lets just say I had to come up with a cheaper option..
The Hillbuilt was born.

A 130 amp alternator I picked up at U-pull &Pay for 25.00 bucks..

The custom made bracket.

The install ,removed the a/c compressor and bolted the custom made bracket to the mount.

The first weld with a set of jumper cables as the leads.. Heck it was a test couldn't believe it turned out that well.. I had one hand on the welding lead and the other on the throttle speeding up the engine for amps.

So the Hillbuilt is borned ( Trademark and patent pending)

A video to follow ..

Comments,Concerns,and input welcome.

Sweet!

I know there's a way to bump up the idle, but I'll be damned if I can think how at the moment...

And I guess you have to signal the new alt when you want it to charge, right? So it doesn't run all the time?

Details, son! Details!

(Otherwise, how the hell are the rest of us supposed to infringe on your patents?!?)

Yes all good questions my friend..

The throttle. I'm thinkin' bike lever shifter & cable assy.

The wiring is still work in progress. Yes it will not run all the time.. Input welcome..

Did a little searchin...

Apparently, the later (post-renix) Police-issue XJ's had an "Extended Idle" switch that'd bump the idle about a grand.

Kicker is, the PCMs are all the same, so the circuitry is there. Find the right lead, ground it through a switch on the dash, and bingo.

More info worth mentioning...

The alternator...
As mentioned purchased from You Pull & Pay for 25.00 bucks.
Removed from a 1998 Ford Expedition 4.6 engine.
It's a Auto Zone Reman Duralast Part# DL350-16 130 amp.

The wiring...
To get the alt to charge and/or weld I did the following.
The orange wire on the A terminal of the regulator was supplied with constant 12 volts.
The green wire on the I terminal of the regulator was supplied with 12 volts when I was ready to weld.
The output terminal for the welding lead and /or battery charging connection.
The ground lead was clamped to the alt body and to the metal being welded.

I'm thinking about making a elect box.. Guess I could buy one I have seen several different ones on other welding setups.

My goal to keep it simple and on the cheap. Out of pocket so far 35.00 Bucks
