Whats the difference between the two welding wire
I have two spools of welding wire for my HOBART Mig
1. MIG Solid Welding Wire
2. Gasless Flux-Cored Welding Wire (came with the hobart)
What are the difference between the two and what effect will I get from both. Does one burn hotter? Is one more likely to get a burn through
Also in terms of diameter of the wire. I have a 30 diam and a 35. Is there a big difference in effect. Will I get a better weld with the larger diameter or smaller.
Thanks to those who respond.

The solid wire is for use with shielding gas. The flux core does not require gas.
Someone else will have to answer your other questions as I am too new to welding. I would suggest going to the Miller web site, they have some good materials there. Some are free and some are for sale. Their MIG book is $25 and appears to be very complete. They also have welding slide calculators available which probably answer your questions.

sancochojoe,
If you are fairly new to welding, you're going to want to use the solid wire with gas. The reason for this, is that you will be able to SEE what's going on at the weld puddle, rather than it being obstructed by the molten flux.
I'm guessing the wires are two different diameters due to one having a flux core. In theory, they should both yield the same amount of weld.

I've got a little Mig100.. Nuthing special, but it works on heavy sheet metal. Anything more than that I like to use the stick, -An old 220 Airco.
My question for anyone is: I use the gas-less flux core wire in the mig. I'd like to use it on aluminized exhaust or other than stainless exhaust pipe. Is there a flux core wire available for both purposes? Is there a flux core wire for stainless exhaust pipe?

Esab makes a 10# spool of .035" dia. 308 alloy stainless flux core wire that will run you about $250-$300 bucks. Use solid wire with gas.

Sancochojoe, wire diamater depends on how much machine you have. I can run 030 or 035 in my 180 amp machine with no problems, but I HAVE to run 023 in my 110v/ 130 amp. So if you have a big enough machine you can run most anything. I agree with RocketScience stay with the solid w/gas. I have never gotten the hang of flux core and I have been welding almost 30 years.

.045 dual shield (flux cored wire) with mixed gas makes for easy welding on heavier mat. and very pretty welds. The slag just peels off similar to 7024 rod. Interesting results can also be obtained with soild wire and using mixed gas instead of CO2.
