Very similar to mine, a millermatic 185, 20+ years and still on the same gun & liner. But it’s rarely used.

Those old transformer welders are the Toyota’s of welders. I’m not even sure how old mine is to be honest. My brother had it for years in Montana and I long term leased it (eventually giving him what he paid for it).

On the original liner…wow. Kinda like having a classic car. Pretty cool.

If the design is not junk then explain why Toyota had only the biggest frame recall due to premature rust ever.
Theres no way in hell if this frame was all or mostly one piece it would have rusted this fast, are you a engineer do you work for Toyota?

Also the two pieces of metal together are a half inch (measure calipers told me this) have you ever tried to weld two pieces riveted together or you just troll about things that are hilarious ?

The biggest reason is the cats are too close to the frame. Another reason is too thin of steel to meet EPA mileage requirements and to meet number cruncher requirements.

The frame not being made from one piece of steel isn't why the frames fail from rust. I do not and have not ever worked for Toyota. I do not have a engineering degree. From scratch/raw steel trailer frames, half of a truck frame for a SAS, and a couple of complete hot rod frames.

I have welded 2 pieces that were riveted together by the factory on that SAS job.

And my previous comment was over the top and unnecessary. My sincerest apologies.

I would *highly* suggest doing some learning on metal construction, fabrication and welding before you go anywhere near your truck. There are things there that are constructed the way they are for a reason, and most of the time, it’s a good one. Sometimes it’s an economic reason, but many times it’s an engineering reason.

After that, carefully consider the long term effects of whatever thing you intend to do here and whether it’s going to work out or just cause more problems. Frames are not a good place to learn to weld.

Nahh man, that frame design is junk. OP said so

You obviously have not worked on a NE chevy or 3rd gen dodge ram. You see the difference is the clientele of purchaser. I've seen just as many Chevys, Dodges, and Fords same issues same ages or younger. The loudest whiner gets the pacifier. Hell I was replacing cheap ass plastic plug wire looms on 20+ yr old chevy, buick, olds, pontiacs under recall because they could collect oil from a leaking valve cover gasket and cause a fire . There are 100000s of recalls from all manufacturers some actually good some like the toyota frame recall were based off a lawsuit and are good will recalls more so than safety.

The most accurate post this website has ever seen.

it sounds as if you don't know how to weld...

tackling something structural??? i guarantee you will ruin it and possibly the whole truck. probably injur yourself...

where do you live???

do not attempt this, FIND ONE OF US THAT IS NEAR YOU, to do it for you.

I am in new Orleans

I know how to weld but I MIG weld exhaust pipes sometimes stainless manifolds; not frames that have rust issues.
Maybe its mostly metal treatment like i said before if you have multiple pieces of metal this is just spaces water can get into. Everything I am finding on this frame is all where water got into grooves some big enough to put end of screwdriver in between the two pieces of metal.
So no matter what the reason too many spaces = water getting in and sitting there.

The CATs being too close to the frame and thin metal is good info. I know how close the CATs are but did not know the metal is so much thinner there. I will say the frame does make a weird narrow shape the closet in gets to connecting with the front area of frame near motor mounts.

For those of you who do not like my posts feel free not to listen.

But for those who want to contribute something real answer this.

How many other frames have you encountered that are made from this many different pieces of metal? On vehicles made in last 30 years? You speak as if this is completely common....

Has anyone had any good experiences with Eastwood internal frame coating ?
