So basically, what you're sayin is that you're just pissed you cant do this and want to bitch about it...

...Seriously. :rofl:



In case you're bored:

Welding cast alum is NOTHING like welding cast iron. Welding cast is a bitch and a half. It requires you to preheat the material, keep it there during welding, and then let it cool down over a period of DAYS... oftem involving wrapping it in insulation, and other weird methods.

Do you know how much cast iron rod costs? Around $50 a carton... If they bought the rod, they need to use it to pay it off.

GTAW is NOT hard, maybe you just need more practice? Of course most people with even a little bit of sense will take a course or two at their community college before investing in an expensive machine like a welder.

I hear so many people bitch about how "They hate TIG welding". It provides the control of Oxy-Acetylene, but is so much more versatile. It's also one of the cleanest, and most relaxing welding processes out there. Every try doing overhead or vertical up SMAW? (Stick)

Buying anything used is a gamble, nuff said.

Can you even TIG for 2 min without pausing for readjustment? Most welds dont take over 2 min to do, unless you're doing some crazy thick metal, in which case you would buy a bigger welder. On a car, most metal only goes up to about 1/4 thick, or if thicker, it's normally very little sections of it. For the average hobby guy, a 20% duty cycle ain't that big of a deal, cause the wont even get near it half the time.

Case in point, this would be a perfect used welder to buy from someone who's upgrading.

lol... this thread turned out pretty cool.

Im not going to waste my time trying to prove to some guy over the internet by paying for dyno time. I know from my own experience what works and what dosnt. and i'll leave it at that.

and i dont know why your sweating over a ESAB??? lol... Lincoln or Miller are the only 2 respected welders in the business.

No, now you're putting words into my mouth.
I'm just being honest - I wouldn't touch trying to TIG cast aluminum, period.
See below for why.


Ah, finally someone who actually knows what they are talking about.
I was going to blast whoever said cast iron is basically the same, but I figure I'd be nice about it...


I have a friend who does this for me.
Why bother learning it when he's the one with the welder, and he's the one that's good at it?
Currently, it's a waste of my time, as I'm busy taking care of other things that are of higher priority.


My friend owns an older Miller TIG 180.
It's rated at 40%, and he does work that requires it to be cooled down between welds.
He's already bitching about the 40% duty cycle.
I can't imagine cutting that rating in half would do to his welding work production.
He's already talking about stepping up to 220A or 225A rated TIG, but that's a big step up in price.
BTW, we do a lot of intercooler core installs with custom brackets.
Big IC cores suck up a lot of heat, some amps and duty cycles do count.
Most of our brackets are at least 1/4" thick...

This is getting way off topic now...
You're welcome to PM me if you want to discuss this further.
...or start a new thread.

This just shows me how inexperienced you are.
Lincoln actually has a bad rap by some experienced weldors.
And if this is jab at ESAB, you have no idea what you are talking about.


-Ted

Wow, I guess I have no sense whatsoever. I bought a Sync 200 a bunch of years ago, read a book, talked to a few pro's and had at it..... I'm an idiot for thinking I could learn a skill myself.

You see, this thread is why I don't fab my own stuff... I have enough heart burn as it is :)

Geez, I make a two-sentence comment just complimenting the OP and this turns into a another 'show me the numbers' match. I would like to see some numbers as well but sometimes, it's just not a priority so too bad for the rest of us. I just thought it was neat; rarely does anybody do anything with the stock IC.

I will fabricate my own stuff if it doesn't include welding. If something needs to be welded, I know a good guy that always does our custom lab equipment. And yes, he's good with aluminium.

We did a project car that used two stock IC cores.

Haltech datalogs show it was within 3 degree F of a full GReddy FMIC kit for the FC3S.

Is that what you want?


-Ted

lol... your right. im a newb.

except for my certification in: GTAW, FCAW, SMAW, GMAW, Oxy-acet., ect. ect. in stainless, various carbon steels, aluminum... in ALL positions and unlimited thickness.

Im no garage welder. I know what im doing. And if you want to go ask 30-40 year veterans what they weld with. Or just drop by a job site and see what they are using. Red or Blue...

... sucess is mine. =P

That wasn't exactly what I had in mind, Ted- although that itself is also interesting. I was more or less referring to the fact that there aren't many TMIC modifications (not including the AI systems) that build upon the existing system. IMO, it always seems too easy to just slap an FMIC on and call it a day.

It's just nice to see somebody think and do outside of the box.

Cheers, everyone.

I know that this dyno proves absolutely nothing since there is no before and after. But the power band and numbers are better than i have ever seen for whats done to the car. up until the bad dip in power at around 5500rpm, wich will be resolved very soon. I will be going back to the dyno in hopes of 250whp with the problem fixed...

Hey man I commend you on upgrading the stock TMIC, the work looks clean IMO. For some reason it seems that people feel the need to make things difficult. It's funny to me how this was a thread just showing one mans effort in making something better to what brand welder is better. Honestly most of the guys I know use Lincoln a few use Miller & a couple use Hobart or ESAB. My brother who has done deep sea welding & welding at prefab concrete company prefers the Lincoln.

So, what's the dip from? It looks like the run with the most peak power has the most significant dip, even lower than stock. What was the AFR ratio? Was this a problem of HP, or is it a fuel/timing issue? Is your ECU stock or standalone?
