Wire Feed Speed
Wire feed speed is crucial for cheap gasless MIG welders. Lower-priced models offer a wire feed speed range of 40-500 or 600 inches per minute. This still allows for adjustments based on weld thickness. Higher-end models have more precise controls and can go up to 700 inches per minute.
Power Settings
Power settings are equally crucial for gasless MIG welders to adjust the welder to different welding tasks. Most cheap models only offer a power output range of 30 to 140 amps. This power level can handle a wide range of welding tasks from light to medium, and is usually sufficient for DIY projects and repairs. However, most general-purpose welders need to increase the power to 200 amps for more demanding tasks to ensure deeper penetration and stronger welds.
Portability and Ease of Use
One of the advantages of cheap gasless MIG welders is their portability. These units typically weigh 25 to 40 pounds, making them easy to transport and set up. In addition, their design and ease of operation make them user-friendly, especially for beginners. No need to carry a gas cylinder, further enhancing portability as there is no additional equipment to carry.
