Product specs
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 ALPHA MMA-1000A is a 380 V, 50/60 Hz DC manual metal arc welding machine designed for high-current welding and carbon arc gouging. Its published operating range is 40–1000 A, with a rated output of 1000 A at 44 V, an 80 V no-load voltage, and an 83.3 kVA rated input capacity.
The machine uses soft-switching inverter technology with four IGBT modules. Operator controls include a digital current preset and continuous adjustment of arc-starting and arc-force current. The stated electrode capability covers alkaline and stainless steel electrodes.
Protective functions are listed for undervoltage, overvoltage, and overcurrent conditions. Published specifications identify a 60% duty cycle and 80% efficiency. The enclosure rating is IP21S, the insulation system is Class F, and cooling is by air.
Machine dimensions are stated as 68 × 35.5 × 96 cm, with a stated machine weight of 69 kg. Carton-box and wooden-box transport packaging are listed. Before procurement, buyers should confirm the exact ARC-630A/1000A configuration on the quotation and nameplate.
The source description also contains a separate 100% duty-cycle statement that conflicts with the 60% value in the parameter table;the required duty cycle should therefore be verified in writing for the intended output and ambient conditions.
Buyers should also confirm input-current and circuit requirements, included cables and accessories, suitable electrode and carbon-gouging consumable ranges, packaging dimensions and gross weight, and the environmental limits associated with the IP21S enclosure.
