Lincoln Electric vs AWithZ Specs
Welding process
The Lincoln Electric 90i handles MIG and flux core wire feed welding. It works with flux-cored wire up to 1/4 inch thick or solid MIG wire up to 3/16 inch thick. This makes it suitable for general repairs and small jobs. The AWithZ UF20B is a capacitor battery spot welder. It is designed for joining thin metal sheets like nickel-plated or stainless steel. It targets cylindrical battery pack assembly. The Lincoln Electric unit offers broader versatility for structural joins. The AWithZ tool is specialized for electronics and battery work. You need to choose based on whether you join thick steel or thin battery tabs.
Power output
The AWithZ UF20B boasts a maximum pulse welding power of 10KW. This high wattage allows for quick, strong spot welds on thin materials. The Lincoln Electric 90i does not list a specific wattage or amperage rating in the provided data. It focuses on smooth operation through an inverter power source. The AWithZ machine delivers concentrated energy for specific spot welding tasks. The Lincoln Electric machine provides continuous wire feed for longer seams. Without specific amperage data for the Lincoln unit, the AWithZ stands out for its stated 10KW pulse power. This makes it ideal for high-current, short-duration applications like battery manufacturing.
Input voltage
The Lincoln Electric 90i requires a standard 120V input. This allows you to plug it into any regular household outlet. The AWithZ UF20B accepts a wide voltage input of 100-240V. This flexibility lets you use it anywhere in the world with the right adapter. The AWithZ unit also requires a 15-amp high-current adapter for fast charging. Both machines are portable, but the AWithZ offers broader electrical compatibility. The Lincoln Electric model is limited to 120V regions. If you travel or work in different electrical environments, the AWithZ voltage range is a clear advantage.
Portability
The Lincoln Electric 90i weighs 15 to 19 pounds depending on the variation. It includes a shoulder strap and a metal case for protection. Its compact dimensions of 10 inches on each side make it easy to carry. The AWithZ UF20B is described as compact with a rounded aluminum alloy shell. It includes a charger cable and foot pedal, adding to the carrying load. The Lincoln Electric unit is explicitly designed for mobile welders and maintenance work. The AWithZ machine is stationary during use, requiring connection to wall power. For true mobility on job sites, the Lincoln Electric design with its strap is superior.
Control modes
The Lincoln Electric 90i uses two simple knobs for wire speed and voltage. It offers infinite welding voltage for fine-tuning characteristics. The AWithZ UF20B features three modes: automatic, manual, and foot pedal. It has 99 adjustable gears for different material thicknesses. The foot pedal allows for hands-free operation, which is useful for precision work. The Lincoln Electric controls are straightforward for beginners. The AWithZ offers more granular control and automated options. If you need precise adjustment for varying battery types, the AWithZ modes provide more flexibility. The Lincoln Electric unit is simpler to operate for general tasks.
