Am brand new to welding. Will become just a home hobbyist and repair my own things. Always hear good things about Miller welders. Will probably buy one in the very near future. Just went to the local farm store and was looking at welders, and thought I spyed Miller welders on the shelf. Same color blue but were Clarke. Not the same I assume. Any info from veteran home hobbists or professionals would be greatly appreciated. What size MIG would I need?
