What’s this welder’s job? Mild steel may be used for home, garage, and workshop repairs. In addition, it’s useful for modest agricultural, vehicle, and metallurgy repairs. This welder can’t handle heavy jobs. For example, it’s not designed for high-powered burning, like welding rusted metal. Also, it can’t handle sloppy welding repairs.

It’s not designed for high-powered burning, like welding rusted metal. The welder’s duty cycle shows that it’s best for light to medium work. The output voltage is just 70 amps at 20% duty cycle. This means you can weld for 10 minutes before the equipment overheats. After then, let it rest before welding again. The K2278-1 Handy Core has an output range of 35 to 88 amps. The highest duty cycle of this welder is well below 20%. 18-gauge to 1/8-inch mild steel is processed.

This MIG welder has two unique voltage switches. Both are rocker switches but serve different functions. First allows you to choose the high or low mode, second 1 or 2. This welder safety feature is very good. The welding wire becomes heated when you press the MIG gun’s button to manage the procedure. This is a feature missing from most welders in this price range.
