Weldpro vs Sunstac Side by Side
Welding processes
W Weldpro offers a five-in-one solution including Synergic MIG, Thickness MIG, Stick, Lift TIG, and Spot Welding. This versatility handles steel, stainless steel, cast iron, and mild steel with gasless flux core options for outdoor work. Sunstac focuses on DC TIG, Pulsed TIG, Spot TIG, and Stick welding. It supports cast iron, alloy steel, copper, stainless steel, and carbon steel. W Weldpro provides more process variety for general DIY and repairs. Sunstac specializes in TIG precision for thinner materials and sheet metal.
Amperage output
W Weldpro delivers up to 140A using IGBT inverter technology. It supports MIG welding thicknesses of 1-4mm and MMA or Lift TIG thicknesses of 1-6mm. Sunstac provides up to 200A output. This higher amperage allows for handling thicker materials and more demanding industrial tasks. The 200A rating on the Sunstac machine gives you more power reserve for heavy-duty projects. W Weldpro’s 140A is sufficient for most home repairs and light fabrication, but Sunstac leads in raw power capacity for thicker stock.
Display technology
W Weldpro features a clear LED display with intuitive control knobs for voltage and wire feed speed adjustments. The interface allows for precision tuning within ±3V. Sunstac upgrades to an LCD digital screen. This display shows voltage, current, and other parameters clearly, even when viewing through a welding helmet. The LCD provides better visibility and easier access to settings compared to standard LED indicators. Sunstac’s screen offers a more modern interface for monitoring real-time welding data during operation.
Portability and weight
W Weldpro weighs 7.5 pounds with compact dimensions of 11.5 x 6.1 x 9.6 inches. It includes a convenient carry handle, making it easy to transport for on-the-go use. The data for Sunstac does not list specific weight or dimensions. You cannot compare portability metrics directly without Sunstac’s physical specs. W Weldpro’s light weight and included handle make it highly suitable for moving between workshops or job sites. Sunstac’s portability remains unknown based on available data.
TIG control features
Sunstac emphasizes pulse TIG and spot TIG capabilities to minimize material distortion from excessive heat. It includes a built-in intelligent parameter saving function to restore previous settings instantly. W Weldpro offers Lift TIG and Spot Welding but relies on synergic control for MIG rather than pulse TIG. Sunstac’s pulse function allows for precise control and cleaner welds on thin materials. W Weldpro’s Lift TIG is functional but lacks the advanced pulse modulation found in the Sunstac unit.
Choose Your Welder Based on Your Needs
You need versatile multi-process welding for home repairs
The Weldpro MIG140 offers five welding processes including Synergic MIG, Stick, and Lift TIG. Its 140A output with IGBT technology handles mild steel and cast iron.

The pulse function minimizes heat input, reducing distortion on thin sheets. Its LCD screen provides clear parameter visibility. Choose this if your primary focus is high-quality TIG welding on stainless steel or copper with greater amperage.
You want a complete kit with included accessories
The Weldpro package includes a 14AK MIG torch, electrode holder, ground clamp, and a foldable helmet. It also provides 2LB of flux core wire and contact tips. Weighing just 7.5 pounds, it is highly portable. Sunstac does not list included accessories in the data. If you need a ready-to-weld solution without buying extra gear, the Weldpro kit offers better immediate value.
