| If you are going to weld heavy stuff, you need a welder that draws a lot of power. When I do 1/8'' stuff with my 110v welder, I kick out the 20 amp breaker sometimes. If you are going to be doing big jobs, better go with the 220. The older style arc welders that use rods are easier to use and less bother to set up for occasional jobs. They work fine on heavier metal. You must match rod diameter to work thickness. The thicker the metal, the higher the amperage. It is much easier to work with Metal Works rod by Lincoln Electric than the stuff Lowes and other s sell.
The gas and gas less wire feed welders ar more expensive and harder to learn to use. They are much more convenient if you are doing much welding at a time. They also work much better on thinner metals. |
