Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Arc Welding Machines. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
The MMA-400A is a portable, one-body manual metal-arc welding machine built around IGBT inverter technology. Its listed AC 230 V, 50/60 Hz input and DC welding output make it a candidate for workshops, garages, and other locations where a compact MMA welder is required.
The welding-current range is 40–400 A, while hot-start current and arc-force current are each adjustable from 0–100 A. The stated electrode range is 1.6–6.0 mm, with E6013 and E7018 electrode types listed. Supported welding functions are MMA, VRD, and Lift TIG.
The machine is air cooled and includes overheat control, overload protection, a cooling fan, carrying strap, and handle. Listed standard accessories are an electrode holder, earth clamp, brush, and mask. The machine measures 416 × 205 × 295 mm and has a listed net weight of 12 kg.
Other stated values include a DC 65 V open-circuit voltage, 0.93 power factor, 80% efficiency, and insulation grade F. The listed plate-thickness range is 1–15 mm.
Procurement note: the source information gives conflicting duty-cycle figures—60% in the basic specifications and 100% at 20°C in the model comparison table. Buyers should obtain the applicable duty-cycle rating and test conditions in writing before selection.
Buyers should also confirm the exact protection-class marking, input phase and plug configuration, whether Lift TIG accessories are included, and which optional functions are fitted to the quoted unit.
Dual-voltage operation, anti-stick, , and generator-friendly operation are presented as options and should not be assumed to be standard.
