120V vs 110V Welder Specs
Input Voltage
The Lincoln Electric 90i operates on a 120V input, while the YESWELDER 135A uses 110V. Both voltages fall within the standard range for household circuits in the United States. This means you can plug either machine into a typical wall outlet without needing specialized industrial power. The one-volt difference is negligible in practical application. Neither unit requires a dedicated 240V line or heavy-duty breaker setup. You get flexibility in where you set up your workspace. Both designs prioritize accessibility for hobbyists and professionals working in standard home shops or residential job sites. The choice between 120V and 110V does not restrict your location options.
Welding Process
The Lincoln Electric 90i supports MIG and Flux Core welding processes. It is designed for solid MIG wire up to 3/16 inch and flux-cored wire up to 1/4 inch. The YESWELDER 135A offers three processes: MIG, Stick, and Lift TIG. It handles gasless flux core MIG welding effectively. This multi-process capability gives the YESWELDER an advantage if you need to switch between different welding techniques. The Lincoln unit focuses on simplicity with two dedicated processes. You save time switching electrodes or torches with the YESWELDER. The Lincoln Electric model remains a solid choice if you only need MIG or flux core work. It lacks the Stick and TIG versatility of the competitor.
Weight
Portability matters for mobile welders or those moving equipment frequently. The Lincoln Electric 90i weighs 19 pounds according to its specifications. The YESWELDER 135A weighs 11.4 pounds. This makes the YESWELDER significantly lighter. You can carry it easily with its built-in handle. The Lincoln unit includes a shoulder strap, which helps with balance. However, the raw weight difference is substantial. The YESWELDER is nearly eight pounds lighter. This reduces fatigue when carrying the machine up ladders or across large job sites. The Lincoln unit is still considered portable due to its small footprint, but the YESWELDER wins on pure weight metrics.
Amperage
The YESWELDER 135A delivers a robust 135A output at 110V. This power level allows it to tackle mild steel up to 3/32 inch thick. The Lincoln Electric 90i does not list a specific amperage rating in the provided data. We can infer it is lower due to its smaller size and lower price point, but the exact number is unavailable. Higher amperage generally means better penetration and the ability to weld thicker materials. The YESWELDER provides a clear numerical advantage here. You get more raw power for the same voltage input. This makes the YESWELDER more capable for slightly thicker jobs compared to the Lincoln unit.
Display
The YESWELDER 135A features an advanced, oversized LED digital display. It shows real-time current during operation, allowing you to monitor settings precisely. This is helpful in bright outdoor environments or when you need exact control. The Lincoln Electric 90i uses simple analog knobs for wire speed and voltage. It lacks a digital screen. You adjust settings by feel and experience with the Lincoln unit. The YESWELDER provides visual feedback that reduces guesswork. This is a significant advantage for beginners who want to see their parameters. The analog controls on the Lincoln unit offer tactile feedback but less precision.
Which 120V or 110V welder suits you
Beginners seeking simple, reliable MIG welding
The Lincoln Electric 90i uses simple two-knob controls for wire speed and voltage. This straightforward interface reduces the learning curve for new welders. It handles flux-cored wire up to 1/4 inch thick and solid MIG wire up to 3/16 inch. The included accessories and metal case protect the unit during transport, making it a solid choice for home repairs and small DIY projects.
Users needing multi-process capability and digital display
The YESWELDER 135A supports MIG, Flux Core, Stick, and Lift TIG processes. It features an LED display for clear setting visibility and synergic control that matches voltage to wire speed. This reduces burn-through on thin metal. The 110V input powers 135A output, allowing you to weld mild steel up to 3/32 inch thick. Built-in safeguards protect against overload and overheating.
Mobile welders prioritizing lightweight portability
The YESWELDER 135A weighs 11.4 pounds, making it lighter than the Lincoln Electric 90i at 19 pounds. It includes a carrying handle for easy transport. The compact dimensions and lower weight make it ideal for on-the-go jobs. The 110V input ensures you can use it anywhere standard power is available without worrying about heavier equipment constraints.
