Plasma Cutter vs TIG Welder Specs
welding process
The ARCCAPTAIN CUT50 is a dedicated plasma cutter. It uses compressed air to slice through metal. This process is ideal for cutting steel, aluminum, and copper. It does not weld. The Sunstac SS-200TP is a TIG welder. It joins metals together using a tungsten electrode. It supports DC TIG, Pulsed TIG, and SPOT TIG modes. This makes it a joining tool, not a cutting tool. You must choose based on whether you need to cut or join metal. These are fundamentally different operations with different outcomes.
amperage
Amperage determines the power output of each machine. The Sunstac SS-200TP offers up to 200A of welding current. This high amperage allows for deeper penetration and faster welding on thicker materials. The ARCCAPTAIN CUT50 is a plasma cutter. Its cutting capacity is listed as 1/2 inch on 110V and 3/4 inch on 220V. It does not list a welding amperage because it does not weld. The Sunstac provides a raw power number for welding tasks, while the ARCCAPTAIN provides thickness limits for cutting. The Sunstac has higher stated amperage for its primary function.
display
Both machines feature digital screens to help you monitor settings. The Sunstac SS-200TP uses an LCD digital screen. The product data states this screen surpasses older LED displays. It shows voltage, current, and other settings clearly, even with a welding helmet on. The ARCCAPTAIN CUT50 uses an LED screen display. It shows voltage and current in real time. It also displays error codes to help you troubleshoot issues. Both screens allow you to adjust parameters without removing your safety gear. The Sunstac claims a superior LCD technology, while the ARCCAPTAIN includes diagnostic codes.
portability
Size and weight affect how easy it is to move the machine. The ARCCAPTAIN CUT50 weighs only 13 pounds. It measures 13 inches long, 8 inches high, and 6 inches wide. It includes a shoulder strap for carrying. This makes it highly portable for job sites or tight spaces. The Sunstac SS-200TP data does not list weight or physical dimensions. Without these numbers, you cannot compare the portability directly. The ARCCAPTAIN is explicitly designed for ultra-portable use. You have clear data favoring the ARCCAPTAIN for easy transport.
material compatibility
Each machine handles different materials based on its technology. The ARCCAPTAIN plasma cutter slices through steel, aluminum, and copper. It is designed for cutting various metals cleanly. The Sunstac TIG welder joins cast iron, alloy steel, copper, stainless steel, and carbon steel. It also handles sheet metal and thinner materials with precision. The Sunstac offers versatility in joining different metal types, including harder alloys. The ARCCAPTAIN is limited to cutting operations. If you need to weld cast iron or stainless steel, the Sunstac is the only option here.
Which machine fits your project
Metal fabricators needing precise joins
The Sunstac SS-200TP handles DC TIG, pulsed TIG, spot TIG, and stick welding. It reaches up to 200A, allowing you to join stainless steel, carbon steel, and copper with precision. The LCD screen displays clear parameters, and the pulse function minimizes heat distortion, making it ideal for thin sheet metal and detailed fabrication work.
DIYers cutting steel or aluminum
The ARCCAPTAIN CUT50 is a dedicated plasma cutter for slicing through metal. It supports 110V and 220V input, cutting up to 1/2 inch thick steel.
