About these itemsThis handheld arc welder delivers strong welding power with adjustable current ranging from 20â130A, 20â120A, or 20â140A, depending on the model. Each unit includes precise control via digital or 5-level adjustment systems, making it suitable for welding iron and steel with a maximum thickness of 0.12" (3 mm). The digital display or control knob ensures accuracy for both professional and DIY tasks.Built with advanced IGBT inverter technology, these compact stick welders offer a stable arc, minimal spatter, and high efficiency, resulting in smooth, clean welds. Reduced material loss and consistent output quality allow users to complete welding jobs quickly and effectively.These portable welders are compatible with welding rods ranging from Φ1.6 mm to Φ3.2 mm (1/16" to 1/8"), making them suitable for home maintenance, automotive repair, and machinery fabrication. Safety features include overheat protection, hot start, and anti-stick functions, ensuring stable operation and protecting both users and equipment.Each model is compact, lightweight, and designed for single-handed use. The 130A model includes a plastic storage box for secure transport, while the 120A and 140A units come with a soft cloth storage bag. Whether in a garage, workshop, or outdoor site, these welders are easy to carry and ready to go.Every set includes a complete accessory kit. Depending on the model, accessories may include welding rods, a folding welding helmet or safety glasses, gloves, a brush, and a 1.5 m ground wire. These kits offer everything needed for metal joining tasks at home or in the field.Key DifferencesThe MMA-130A model provides a stepless current range of 20â130A with a digital display for precise output control and includes a hard plastic storage box for durability. The MMA-120A and MMA-140A versions use a 5-level current adjustment system with ranges of 20â120A and 20â140A respectively, offering tailored power depending on task requirements. While all models share key features like IGBT inverter technology and welding rod compatibility, the MMA-140A stands out for its higher maximum current and greater rod quantity (20pcs) included. The MMA-130A weighs slightly more and is suited for users preferring rigid casing, while the MMA-120A and 140A are more compact with cloth bags for easier transport.SpecificationsMMA-130A-AUStepless Current Adjustment: 20 - 130 AmpCompatible Welding Rods: Φ1.6 - Φ3.2 mm (Φ1/16" - Φ1/8")Input Voltage: AC 115VInput Capacity: 4.6 KVADuty Cycle: 30% @ 40°CInverter Technology: IGBTPower Factor: 0.76Welding Thickness: Max 0.12 in / 3 mmAdvanced Features: Overheat Protection, Hot Start, Anti-StickProduct Weight: 7.03 lbs / 3.19 kgProduct Dimensions: 10.24 x 3.74 x 10.63 in / 260 x 95 x 270 mmMMA-120A-AUAdjustable Current: 5 Levels, 20 - 120 AmpCompatible Welding Rods: Φ1.6 - Φ3.2 mm (Φ1/16" - Φ1/8")Input Voltage: AC 110VInput Capacity: 4.6 KVADuty Cycle: 30% @ 40°CInverter Technology: IGBTPower Factor: 0.76Welding Thickness: Max 0.12 in / 3 mmAdvanced Features: Overheat Protection, Hot Start, Anti-StickProduct Weight: 6.28 lbs / 2.85 kgProduct Dimensions: 9.84 x 3.94 x 9.84 in / 250 x 100 x 250 mmMMA-140A-AUAdjustable Current: 5 Levels, 20 - 140 AmpCompatible Welding Rods: Φ1.6 - Φ3.2 mm (Φ1/16" - Φ1/8")Input Voltage: AC 110VInput Capacity: 4.8 KVADuty Cycle: 30% @ 40°CInverter Technology: IGBTPower Factor: 0.76Welding Thickness: Max 0.12 in / 3 mmAdvanced Features: Overheat Protection, Hot Start, Anti-StickProduct Weight: 6.70 lbs / 3.04 kgProduct Dimensions: 9.84 x 3.94 x 9.84 in / 250 x 100 x 250 mmPackage ContentsMMA-130A-AU1 x Plastic Storage Box5 x Φ2.5 mm Welding Rods1 x Safety Glasses1 x Pair of Welding Gloves1 x Welding Brush1 x Welding Ground Wire (1.5 m)MMA-120A-AU1 x Cloth Storage Bag10 x Φ2.5 mm Welding Rods1 x Folding Welding Helmet1 x Pair of Welding Gloves1 x Welding Brush1 x Welding Ground Wire (1.5 m)MMA-140A-AU1 x Cloth Storage Bag20 x Φ2.5 mm Welding Rods1 x Folding Welding Helmet1 x Pair of Welding Gloves1 x Welding Brush1 x Welding Ground Wire (1.5 m)
