Is gasless MIG any better than stick? Isn't it the same thing?? or is the entire MIG machine different?
Okay, when you buy what most commonly call a MIG machine you are actually buying a wire feed welder. There are 2 methods that wire feed welders operate. Flux core welding where the wire has a flux in it to allow the proper chemical stuff to happen and the weld penetrate and work properly. Flux core welding requires no gas. One advantage to Flux core is you can weld outdoors better with it as doing MIG in windy conditions can be problematic. You will also find, especially with a 110 volt welder, that with flux core welding you can get deeper penetration and weld heavier metal. The welds are not a pretty as with the Mig process, but in some cases are stronger. And yes, welding flux core is similar to stick welding. As far as gasless flux core being better than stick is up to the welder. I seldom use flux core on my small Lincoln 110 volt welder. I use it for thinner metal and sheet metal as a MIG. Beautiful welds. I do really like the fact that I can go flux core and weld anywhere I can get a 110 volt extension cord outside. There is a lot of times you may need to weld something in the backyard or somewhere that getting a 220 volt machine to would not be feasible. But if I am welding 3/16" and up structural stuff I get out my big stick AC/DC welder.
Mig uses a solid wire with no flux. A mixture of inert gas is fed to the area of the weld and allows the weld to be made in a zero oxygen environment which helps eliminate oxidizing in the weld and also being there is no flux the weld is smoother.
There are some 110 volt machines that are flux core only machines. The majority though give you the option to go both ways. I strongly suggest you get the machine that allows both. You can add the gas tank later.
