Weldpro vs Haxiaoer Spec Showdown
welding process
The W Weldpro offers five distinct welding processes: Synergic MIG, Thickness MIG, Stick (MMA), Lift TIG, and Spot Welding. This versatility allows you to join steel, stainless steel, cast iron, and mild steel using various techniques. The Haxiaoer is strictly a plasma cutter. It does not weld; it cuts metal. It uses non-touch pilot arc technology to slice through carbon steel, aluminum, stainless steel, and copper. If you need to fuse materials together, the W Weldpro is the only choice here. The Haxiaoer is designed solely for separation and shaping tasks. They serve completely different roles in your workshop, with the Weldpro handling assembly and the Haxiaoer handling fabrication.
amperage
The W Weldpro delivers a maximum output of 140A. This power supports MIG welding on materials up to 4mm thick and Stick or Lift TIG welding up to 6mm thick. The Haxiaoer provides 55A of cutting current. At 220V input, it can cut through metal up to 19mm thick. At 110V, the capacity drops to 12mm max, with clean cuts up to 10mm. While 140A sounds higher, it is used for joining rather than cutting. Plasma cutting requires less amperage to slice through metal efficiently. The Haxiaoer’s 55A is sufficient for its specific cutting duties, while the Weldpro’s 140A is necessary for its multi-process welding capabilities. Both amperage ratings are optimized for their respective functions.
input voltage
Both machines feature dual-voltage input, adapting to 110V or 220V power sources automatically. The W Weldpro identifies the voltage without manual switching, making it suitable for residential or industrial settings worldwide. The Haxiaoer also supports dual voltage, which directly impacts its cutting performance. At 110V, the Haxiaoer cuts up to 12mm, while 220V boosts this to 19mm. The W Weldpro maintains its 140A output regardless of the input, adjusting internally for stability. This automatic detection simplifies setup for you. You do not need to configure settings before plging in either unit. Both brands prioritize ease of use across different power grids, ensuring flexibility for your workspace.
features
The W Weldpro includes intelligent MCU control, adjusting voltage and wire feed speed automatically. It features an LED display, 2T/4T trigger modes, VRD anti-shock protection, Hot Start, and Arc Force. It also has overload, overheating, and short-circuit protection with IP21S dust resistance. The Haxiaoer focuses on cutting efficiency with a non-touch pilot arc, high-frequency inverter technology, and a large LED display. It also offers 2T and 4T modes for controlling the cutting torch. While the Weldpro offers extensive safety and control features for welding, the Haxiaoer emphasizes stable arc concentration and ease of ignition on rusty surfaces. Both include digital displays for clear monitoring of operational parameters.
weight
The W Weldpro weighs 7.5 pounds, with dimensions of 11.5 inches in length, 6.1 inches in width, and 9.6 inches in height. This compact size and light weight make it easy to transport and store. The Haxiaoer’s weight is not listed in the provided data. However, its dimensions are 7.5 inches in length, 11 inches in width, and 15 inches in height. The Haxiaoer is taller and wider, though potentially lighter due to the missing weight spec. The W Weldpro’s 7.5-pound profile is explicitly portable, fitting easily into a carry handle design. For users prioritizing a known, light weight for frequent movement, the Weldpro provides clear data. The Haxiaoer’s bulkier footprint might affect portability, but its weight remains unknown.
Which welder matches your metalwork needs
You need to join various metals
The Weldpro 140A supports five processes including MIG, Stick, and Lift TIG. Its 140A output handles steel up to 6mm thick. The dual-voltage input adapts to your power source. You get synergic control for easy setup. This machine joins materials rather than cutting them, making it the right choice for fabrication and repair tasks.
You must cut thick metal sheets
The Haxiaoer 55A plasma cutter handles carbon steel up to 19mm at 220V. It cuts aluminum and stainless steel cleanly. The non-touch pilot arc ignites on rusty surfaces without scratching. You avoid secondary grinding thanks to the smooth edge. This tool is built for severing metal, not welding it, which suits your cutting requirements.
You want portable all-in-one versatility
Weighing 7.5 pounds, the Weldpro unit fits in tight spaces. It includes a torch, holder, and wire spool. The LED display shows settings clearly. You can switch between 2T and 4T modes to reduce hand fatigue. The compact design aids transport. If you need one device for multiple joining tasks, this multi-process welder offers the most practical flexibility.
