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 WSM-500S is a one-body inverter welding machine combining constant-current DC TIG, pulsed DC TIG, and manual arc welding functions. Its stated input requirement is AC 380 V ±10% at 50 Hz, with 25 kVA input capacity and 38 A input current.
The published model table specifies an 80% load duty cycle and a 72 V no-load output voltage. For DC TIG operation, the welding-current range is 5–500 A. Pulse controls include peak and base current ranges of 5–500 A, a 1–100% pulse duty-cycle range, and pulse frequency adjustment from 1 to 200 Hz.
Additional controls include 10–500 A arc-start current, 5–500 A arc-end current, 0.1–10 second current rise time, 0.1–15 second current decay time, 0.01–9.99 second gas pre-flow, and 0.1–60 second post-flow. The TIG arc-initiation method is high frequency, and 2T and 4T operating modes are listed.
Manual arc welding is also supported, with a stated welding-current range of 5–500 A, thrust-current adjustment from 10 to 200 A, and arc-initiation current from 20 to 160 A. The machine is air cooled and has Class H insulation.
Listed features include an independent air-duct design, water-shortage protection for the welding torch during argon arc welding, automatic temperature testing, and interfaces for robot connection, arc-start signaling, and arc-success signaling.
The stated machine dimensions are 640 × 320 × 590 mm, and the listed weight for the WSM-500S is 50 kg. Standard accessories are described as one 5 m water-cooled argon arc welding torch, one 2 m grounding cable, and one copper connector.
Listed optional accessories include an argon gas meter rated at 25 L/min, electrode holder, welding-machine cart, water tank, foot switch, and water and gas pipes.
Before purchasing, confirm that the offered unit is specifically the WSM-500S and ask for a final datasheet, because another summary field in the supplied information shows a 5–400 A range that conflicts with the 5–500 A model-table rating.
Buyers should also confirm the exact included accessory set, required cooling-water equipment, connector and torch configuration, package dimensions and weight, applicable documentation, warranty terms, production lead time, and suitability for the intended welding process and workpiece.
Installation requirements, input protection, grounding, shielding-gas requirements, automation-interface details, and local electrical compliance should be reviewed before commissioning.
