Welding novice- professional grinder.

As far as welding goes, I suck. No really, my welds look like they were done by Stevie Wonder, if only he developed the steady hands of a parkinson's patient just before the trigger is pulled.

I've been welding for about 3 months, using a cheap 110v reconditioned flux core machine. My neighbor has a really nice Miller mig machine, and his welds are so much stronger and cleaner that mine. Which makes me wonder, does a 110v machines produce a weaker weld than its 220v counterpart?

Are both of the machines using shield gas?

you are comparing apples to bananas here.

in general, yes a 220v is capable of a stronger weld than a 110v machine, but on thinner material, less than 3/16" thick, both will create sufficient welds. most 110V machines are not rated to do a single pass weld on material greater than 3/16"

Gas vs no gas, Flux core burns hotter than a MIG setup but usually results in a less desirable looking weld. Practice comes into play, as does prep work when welding as to how the end product comes out. and yes, a good machine helps, a HF welder will not give a pretty weld every time as it is simply not as consistent as a better machine. But it is capable of good welds still.

His does, mine does not.

Check your polarity to make sure you are hooked up correctly, how much stick out are you running? Get a few pictures of your welds we can probably give you some tips to get better results.

I had a century 220 volt and I just bought a Lincoln and there is a big difference in the welds mainly just more consistent and and I use to weld in a fab shop

It has to do less about the incoming power and more about the quality of machine if all other variables are the same, like shielding gas, polarity (gmaw is dcep and fcaw can be either dcep or dcen depends on wire) type wire size wire etc. The strength technically will be the same if done properly, the wire and base metal will dictate strength.

A "cheap" (HF) 110V flux core will never compare to a quality (Miller/Lincoln/Hobart) 220V gas MIG...end of story! The rest is up to you.
