In high school I learned to oxy/acet weld (coat hangers) and braze so when I bought my TIG it was a natural adjustment, get a puddle and add filler material, this was before MIG. Of course when gas and stick welding you learn to swirl the puddle ....a practice I carried over to TIG and MIG welding by habit
A long time ago I bought an AC/DC 220 amp stick welder which I still have but haven't used in probably 10 years. My Miller 180 MIG took it's place. The last time I used the stick welder was when my neighbor cracked his snow plow frame and needed a quick repair out in the yard. That stick welder is perfect for that old rusty metal when you don't have the time to prep the weld area for the MIG.
Then I got a great deal on a Miller 180 Syncrowave TIG, then rec'd an Eastwood 40amp plasma for Christmas - then bought an Eastwood 140amp (110v) MIG. Mounted the two Eastwood units on one cart and enjoy using them.
I still do some brazing occasionally with the oxy/acet and use those bottles to heat up frozen parts and cut steel when the plasma won't fit the job.
