Bestarc vs BESTMIG Welder Comparison
Primary Function
The Bestarc 50A Pilot Arc Plasma Cutter is designed specifically for cutting metal. It uses a pilot arc to slice through steel, stainless steel, aluminum, and copper up to 2/3 inch thick. It removes rust and paint without surface prep. In contrast, the BESTMIG FLUX-135 is a multi-process welder. It joins metals using MIG, Lift TIG, and Stick methods. It handles flux-cored wire for stainless steel and carbon steel up to 1/8 inch thick. You choose the Bestarc for separation tasks and the BESTMIG for assembly and fabrication.
Amperage Output
Amperage determines the power and cutting or welding capacity of each machine. The Bestarc plasma cutter delivers up to 50A of current. On 220V, it cuts 2/3 inch steel at 50A. On 110V, it handles 1/2 inch steel at 35A. The BESTMIG welder offers a true output of 135A. This higher amperage allows it to weld thicker materials in the MIG, Stick, and Lift TIG processes. The BESTMIG provides more raw power for joining metal, while the Bestarc focuses on precise cutting power for thinner to medium gauges.
Input Voltage
Power source flexibility matters for workshop setups. The Bestarc plasma cutter supports dual voltage input. You can plug it into standard 110V outlets or higher-power 220V circuits. This makes it adaptable for home garages or industrial shops. The BESTMIG welder operates on 110V input only. This limits its use to standard household outlets but ensures compatibility with most residential circuits. If you need to run high-power tools on 220V, the Bestarc adapts better. For standard 110V environments, both work, but the Bestarc offers more voltage options.
Smart Features
The Bestarc includes advanced digital controls and connectivity. It features a Bluetooth app for remote control up to 98 feet away. You can adjust current, switch modes, and monitor status from your phone. It also has a built-in air pressure sensor and a large LED display showing real-time PSI, voltage, and current. Error codes help troubleshoot quickly. The BESTMIG welder features a full-color LED display for real-time parameter monitoring and digital control technology. It lacks the Bluetooth app and remote adjustment capabilities found in the Bestarc, making the Bestarc smarter for remote management.
Weight and Portability
Portability affects how easily you move the tool between job sites. The Bestarc plasma cutter weighs 15.2 pounds. It is compact and portable, suitable for moving around workshops or farm equipment maintenance. The BESTMIG welder is lighter, weighing only 10.7 pounds. It also measures 14.8 inches in length, making it slightly more compact in some dimensions. The lower weight of the BESTMIG makes it easier to carry for extended periods or for beginners who may not need heavy-duty stability. The Bestarc is slightly heavier but still manageable.
Included Accessories
What comes in the box impacts your initial setup cost and convenience. The BESTMIG welder includes a comprehensive accessory kit. It comes with a ground clamp, electrode holder, welding torch, an auto-darkening helmet, and leather gloves. This all-in-one approach helps beginners start welding immediately. The Bestarc plasma cutter includes a metal air filter and a 1/4 inch NPT quick-connect fitting. It requires a standard air compressor, which is not included. The BESTMIG provides more safety gear and tools out of the box, reducing the need for separate purchases.

Frequently asked questions
Can I use the Bestarc plasma cutter to weld metal?
No, you cannot. The Bestarc 50A Pilot Arc Plasma Cutter is designed strictly for cutting metal. It uses a pilot arc to slice through materials like steel and aluminum. It does not have the capability to join or weld metal pieces together. You need a separate welding machine for that task.
Does the BESTMIG welder support dual voltage input?
No, it does not. The BESTMIG 135A Multi-Process Welder operates on a single 110V input voltage. This limits its use to standard household outlets in regions with compatible power. It does not offer the dual voltage flexibility found in some other industrial-grade machines. You must ensure your power source matches this requirement.
Which machine is lighter to carry around?
The BESTMIG welder is lighter. It weighs 10.7 pounds, making it easier to move around a workshop. The Bestarc plasma cutter weighs 15.2 pounds. The difference is about five pounds. If you need to transport your equipment frequently, the lighter BESTMIG unit offers better portability for your daily tasks.
Can the BESTMIG welder handle flux core welding?
Yes, it can. The BESTMIG 135A supports four welding processes: TIG, Stick, MIG, and Flux Core. This versatility allows you to use different types of filler materials and techniques. It is a complete setup for beginners who want to experiment with various welding methods without buying multiple machines.
