nother tools mig140i wire feed their newest model $349.. watch alot of youtube vids before i picked this up and started welding body panels.. first time welding.. im just using .030 flux core even thoe everyone recommends gas, but ill probably switch later on. so far im able to weld 20-24gauge panels .. granted its not pretty and is time consuming since im tacking spots other wise itll burn thru.. 3yr manufacture warranty.. my first welder and so far its pretty simple to use
