Hey, I just picked up a new welding machine (ranger 305G) and I'm looking for an old post about breaking new engine powered machines in.  For the life of me, I can't find it! (I ran out of things to search for, lol)

If anybody remembers the thread, that'd be a big help.  Thanks all!

Take it to a shop where they can load test it for you or run some big rods on it for an hour or better. If you don't you will wet stack it and you don't want that...

I clamp my ground and pos. together  and put my machine on 400 amps and run it for about 4 to 6 hrs.

The thread I was referenced to involved connecting your leads as far as you could get em in each direction to a chainlink fence, setting it at half load, and increasing it at intervals of 50 for x amount of time.  I'm assuming it's the same concept as connecting your leads together and running it at 400 amps (or in this case, 300) to set your bearings in the engine.  I'm looking to clarify break in procedures, as this is a first for me.  :)

same thing

I'm saying this politely-- this is not advisable. Consider the circle of weld current you are creating, right back into the coils. (page B-2 of this Owners manual link advises this should not be done) http://www.mylincolnelectric.com/Catalog/operatorsmanualdatasheet.aspx?p=33994

"Connect the welder output studs to a suitable
resistive load bank. Note that any attempt to
short the output studs by connecting the welding
leads together, direct shorting of the output studs,
or connecting the output leads to a length of steel
will result in catastrophic damage to the generator
and voids the warranty."

Matt- you have a 23hp Kohler on your machine? Since its a new machine and you need to be standing next to it while you break it in (unless you have a load bank) grab a couple handfuls of rod, turn the machine to max and runs holes in a plate of steel for 1/2 hour to 45 mins.

I am by NO means an expert in this area, but I agree that it reeked with the scent of "this is not advisable".

I have again witnessed your priceless value to this great forum we have available to us.

Take care,
John

you really did that?
Parent - - By Mat (***) Date 05-22-2008 22:18 Edited 05-22-2008 22:29
will do, thanks Kaye!

    Mat: What You need to do for a proper break-in is to operate at heavy load intermitently with light or no load in between for cooldown. Burning heavy rod as Kay suggests achives this.

Yes  I did it to my miller big blue 402D I had a miller machenit tell me if I didn,t have a load machine I could do that  so I pull my leads out as far as I could get them and got a steel plate and put my clamp on it

Just run the thing. You wouldnt catch me shorting it out. I might run a couple big rods just to make sure it was working and after that I forget about it.

I'm glad someone brought this up I've run a couple of hours on my freshly rebuild sa 200 and I didn't want to really put it under a huge load I've run some 1/8th rods but I'd got some 3/16 which I may try and burn a little while letting it cool down.

Well, I had some old 1/4" rod onhand, so I broke it in with that.  I cranked the machine right open, and ran stringers on a piece of 3/8" plate for about a half hour.  It burns rod nice.  :)

Thanks for the input, guys!
Parent - By chris2698 (****) Date 05-26-2008 00:35
yeah I ran some 3/16 rods today with mine and after the second rod it deffinitly seems like it was really starting to run even smoother. I gotta take the dang waterpump and thermostat houseing back off and try and reseal it it's leaking on me what a pain in the butt. I hate leaks but other then that boy does it weld good.
