W Weldpro 140A MIG Welder – 110/220V, 5-in-1 Flux Core & MIG/TIG/MMA/Spot

Meet the W Weldpro 140A MIG Welder, a compact, multi‑process power tool designed for both DIY projects and professional workshops. It automatically detects your power source (110V or 220V) and delivers steady arcs with an efficient IGBT inverter. The device supports gasless flux-core welding, making outdoor repairs and on‑the‑go work more feasible without extra gas setups.

Versatile, multi‑process welding for real‑world use

This single machine combines five welding modes to cover a wide range of tasks. It enables precision work on steel, stainless steel, cast iron, and mild steel through these modes:

• Synergic MIG and Flux‑Core MIG for solid welded joints
• MMA (Stick) for thicker or degraded materials
• Lift TIG for lighter heat input and cleaner joints
• Spot welding for quick, controlled links on sheet metal

Welding thickness ranges span MIG 1–4 mm and MMA/Lift TIG 1–6 mm, with gasless flux-core capability supporting outdoor tasks where gas shielding isn’t practical.

Smart control and precision you can feel

The MCU intelligent control automatically tunes voltage and wire feed based on material type and thickness. You also gain fine‑tuning options (±3V) for more complex DIY projects. Features like a clear LED display, 2T/4T trigger modes, and compatibility with 0.030" and 0.035" flux‑core wire enhance setup speed and comfort.

• Automatic voltage detection for 110V/220V operation without manual switching
• IGBT inverter for stable arcs and reduced spatter
• 2T and 4T trigger modes to match task duration and user preference
• Flux-core wire compatibility with common 0.030"/0.035" sizes
• Supports 1 kg and 2 lb spools with tool-free drive roll changes

Safety, durability, and performance in challenging conditions

Packaged with protective features to support longer, safer sessions. VRD anti‑shock, Hot Start for reliable ignition, and Arc Force to prevent sticking are complemented by overload, overheating, and short‑circuit protection. An IP21S rating guards against dust and drips, while an intelligent fan cooling system helps maintain performance from −20°C to 50°C.

• VRD anti‑shock, Hot Start, and Arc Force for reliable starts and smoother arcs
• Overload, overheating, and short‑circuit protection for peace of mind
• IP21S dust and drip resistance for tougher environments
• Adaptive cooling system to support extended use in varied climates

Everything you need, ready to weld, in a portable kit

The full kit includes a 14AK MIG torch (2 m), a 300 A electrode holder with ground clamp, a foldable welding helmet, 2 lb flux‑core wire, tips (0.030"/0.035"), and a hammer/brush. Weighing just 3.4 kg with compact dimensions (292 × 154 × 243 mm) and a convenient carry handle, it’s designed for easy transport and storage. The packaging measures 400 × 245 × 260 mm, making it suitable for home shops and on‑the‑go tasks alike.
