The dual-voltage Hobart Handler is an awesome piece of welding kit, making it an easy contender for our best MIG welder list. The Handler is a substantial beast, and gives the amateur welder a lot of options, from large DIY projects to auto repairs, while an optional spool gun gives you kit to effortlessly weld aluminum. As one of the best welders for home use, the dual voltage is a blessing, meaning you can switch from 115v to 230v in one easy twist. The Handler will then automatically adjust itself to the correct input power to maintain its arc performance. You also get seven voltage settings so you can fine-tune for a precise weld.
