Want to be able to do my own repairs on outdoor power equipment, and put my inventiveness to work (you know what I mean). No welder yet, and never welded, but sure I can learn. I guess I need a welder capable of doing 1/4" mild steel. Gasless, wire-feed type looks to be simplist set-up, will it serve my basic needs? Looked through catalogs, like Northern Tool; some units are even 120V, Should I forget that? Assuming I need a 220-240 input, how much output amperage can I get by with? (I don't have big bucks to spend). Thanks in adance for any help.
