so i need to weld my axle tube and a brace on my 14b and i need to know
im workin with a lincoln AC/DC welder.
1. what type of electrode would you use
2. how hot should i run it?
thanks guys :bow:
 
7018 1/8" rod running at about 130 amps, DC reverse...

You can't go wrong listening to Rene when it comes to welding/fabbing...

what he said:D

That could be. At any rate, for the original posters benefit, Rene knows his stuff.

Personally, i'd rather throw the stick welder in the river. :haha:
 
It's a good skill to have, and it still has it's place...although some of the newer flux cored wires are making it more and more obsolete. It's getting more and more common to see the suitcase feeder units on job sites instead of hundreds of feet of stick cables. Better depostion rates and speed, same quality.

For home sometimes it's just what you have. it is really good for thicker materials, conversely it kinda sucks for trying to patch body work. :D

Arc welders are alot cheaper..... that's about all they have going for em now a days. It is great for thick stuff but like Rene said, dual shield is just as good(maybe a LITTLE bit weaker) and alot faster. Nothing penetrates like Arc though.

I don't think the typical dual shield FCAW is any weaker than 7018. Both electrodes are 70KSI tensile, and every dual shield FCAW wire I've run with straight CO2 shield dug like a friggin backhoe. Much prettier uphands with FCAW too.

I've done countless jobs that were X-ray without trouble. 7018, 11018, FCAW/CO2, MCAW/trimix, MIG/92-8, they all have their strong suits. For speed and depostion rate it's Metal cored wire hands down. Lots of position work, plus strength critical...Dual shield flux core with CO2.

True... I've just noticed that while welding on cast heavy equipment parts, dual shield/FCAW liked to crack more then ARC when welding on "iffy" quality cast.

Also, theres no doubt that FCAW digs uphill but if you crank a heavy duty ARC welder up and weld horizontal/flat it sure seems like it digs deeper then a mig/dual sheild setup. I've found that dual shield has more of a tendency to fill as long as you stay in your puddle even when cranked way up... Arc just keeps diggin and diggin whether your in the puddle or not....(atleast that was my experience) plus you can basically control your "wire/rod speed" while maintaining the same heat with arc.
 
The only drawback to FCAW I found is if you get carried away with the wire speed (trying to get er done) slag inclusions can be an issue. It's much harder to get those with stick.

metal core is an great process, biggest upside is it's the only process I've used that is able to burn out porosity. Every other process requires copious grinding to get it all out before welding over the problem. I did a Metal core test plate (X-ray) and got porosity in the root. My shield gas line was kinked and I didn't notice. I didn't even grind anything, just poured a nice hot one over top and ran with it. The test plate passed with zero 'indications'.

Biggest downside to Metal core is it's pretty much flat/horizontal only.

We used to run vertical stringers with dual shield flux core, the weld inspector didn't like weaves of any sort. Once you got it set right it was hard to discern them from welds done in the flat...

i would love to get a mig but for now i only have an arc so that's what I'm working with. and if your asking me about my experience its very little. i took a college class and have done about 5 small projects but im not good by any means just yet. thanks guys
 
if you have an ac/dc machine make sure you run the stick on dc, and set your cables so the electrode is positive DCEP
as for the rod 7018 great rod for all position, just pick the right diamiter rod for the job and it will make your life easier, also if you are welding alot of stuff in the flat position you could use what i call farmer rod 7024

I was taught to "stack" the weld when welding vertical.... our inspector didn't care whether we weaved or not but most ran stringers. I've learned to run circles running uphill making long ocelations. Comes out real nice when done right.

Yeah I was talking to the orinigal poster. The person telling him could have been welding 50 years. But if the person he's telling dosent know what's going on, its useless as jake brakes on a mule


You've gotten some good info, practice first and give it hell
