Ask your WELDING questions here.

I'd love to have one. They are cost prohibitive for a hobbyist. I am welding together a custom fuel tank and may use a 110v stick welder and a very small diameter welding rod, or a standard oac torch. I love to fusion weld, and that may be what I end up having to do with this tank.

I'm a welding noob. Just picked up a cheap mig and am looking forward to experimentation.

Gonna check out the links in the OP. And use this thread as a reference.

Thanks in advance for all the expertise.

I'm headed out myself o get my 1st tig welder, I have been looking pretty seriously for a good used machine for some time

I think i found one, I had narrowed my searches to the syncrowaves, or dynasty (yea sure they are pricey and out of my range even used) or the Precision TIG 275, tere have only been a couple very old licoln 300's I have seen, but I don't want that old.

found a Syncrowave 351 complete setup to go look at today. hopefully it works out ok!

What do you guys weld on?

I plan to get some heat tiles, but what can I weld on with a torch in the mean time?

I know concrete is a big nono.




Also, for my first big project I plan to make a colapsable welding table.

What kind of steel should I used?

I've got some practice with torch welding, but I don't know anything about steel types or which ones can be welded together and what kind of filler rod to use.

well, I have it, it's on the trailer still, but it is here. Picked up an Argon tank a couple days ago too. now to get it off the trailer and hooked up and use it, what was cool is, a friend here (Ethan) went along to look the machine over with me and try it out.

Nice pickup..you will like the way it welds aluminum.
I have used them all at one time or another. The very best is of course the OLD miller Gold Stars with the selenium rectifiers (yes I still have one )

But I also have a ton of time under the hood with the old Lincoln heliarc welders and like them also.
The great thing about the square wave machines is when welding larger pieces of aluminum. The added DC really make them fast. I just don't like the noise.

EvilGenius,
It really depends on how big of a project you are welding on. But you will end up with a steel table once you get more time under the hood.

Metal, mostly, although some people claim to be able to weld plastic.

I saw, once, maybe on tv- some guy got two pieces of metal to stick together, but he didn't use any glue. Any ideas on how to do this?

I mean like what do you sit your metal on when you weld it.

They're called "Magnets" and they are magic.

You can diffusion bond metals together as well. Good clean surfaces, good pressure holding them together, then add a little heat. Usually happens by mistake to things like brake bleed screws, bushings.

Precision ground surfaces with no oil on them are exceeedingly difficult to separate. Just ask the guy here at work who messed up a set of gage blocks about that.

Thanks, can't wait to hook it up, got busy and have not put in the new box, i looked for a plug so I did not have to hard wire and the only ones I found were about 300 bucks (ouch) so I tried to go with the 100 amp stage [pin, but no one had them in stock in all of Atlanta!

First, a piece of 1/4" Hot rolled plate set on top of my wood workbench (or on top of a couple of sawhorses).

Later I built a small table (first real project- 2' x 3'), and then bought one from a guy (4' x 4' and cheaper than the cost of materials).

I may have suggested this earlier, but head over to the hobart welding board. Lots of ideas, and lots of advice over there- http://www.hobartwelders.com/weldtalk/

tmgs, I have that exact same welder. Been using it for many many years. A base model 351 with no upgrades. Heavy sucker eh?

No problems at all except it's hesitant at times with hf starts. This trait seems somewhat common on blue machines.

I use a momentary switch on the torch 95% of the time and a pedal when welding alum etc.

I have a full system from HPE Exhaust. It is made from Inconel and or Inox.

How is this stuff welded?

Metal table (you can use wood or concrete but not plastic) or just use a vice. the thicker the top the better, one of mine is 3’ x 4’ x ½” the other is 1’ x 4’ x 1 ½”

Here is a picture of my dads it is about 4’ x 6’ x 2” :eek1

you'll need inconel filler and keep as much O2 away as possible. iirc it welds like Ti which is'nt bad as long....

Awesome.

Where did he get that vice?

I finally used up the spool of flux core wire that came with my Hobart 140 so today I bought a tank of C25 and an 11 lb spool of solid wire. I don't know what possessed me to buy that much instead of a 2 lb spool since I just putz around the garage and go months between welding so 11 lbs will last me quite a few years. What's the best way to store the wire to keep it from oxidizing between uses? The guy at the welding supply place suggested hosing it down with something like WD40, but that seems like it'd only contaminate the wire. I'm thinking of removing the spool and sealing it up with a little bag of dessicant using the "Seal a Meal" vacuum bagger my wife has in the kitchen.

EDIT: I just came up from the shop where I laid down my first ever beads using shielding gas. Holy shit! I knew there'd be an improvement over flux core, but DAMN. I'm kicking myself for waiting.

Hey, its MIG welding, its a friggn' squirt gun, wd-40 won hurt a thing. Now, if you were TIG welding, that would be a completely different matter entirely.

We do alot of Inconel

I'll recheck our parameters tonight.

Till then.

Is someone trying to screw me over when he says that all mods are professionally done?
He never said anything about the exhaust...I thought it was all stock, but it doesn't look like factory weld.
