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 Shifeng ZX7-1250 is a vertical, air-cooled inverter machine described for carbon arc gouging and arc welding. Its stated three-phase input requirement is AC 380V ±10% at 50/60. Hz. The listed configuration includes the power source, a 4 m gouging torch, and a 2 m grounding cable.
The published parameter table specifies a 20 k. Hz inverting frequency, 82 V no-load voltage, 76 kVA rated input capacity, 30–1250 A current range, 4.0–16.0 mm carbon-point diameter, 80% efficiency, Grade F insulation, 690 × 365 × 690 mm dimensions, and 85 kg weight.
The same listing also describes soft-switching IGBT inverter technology, DC output polarity, digital current presetting, and continuously adjustable arc-starting and thrust current. Undervoltage, overvoltage, and current protection functions are stated.
Supported electrode descriptions include acid, alkaline, stainless steel, and cast iron electrodes. Installation information calls for an input cable of at least 16 mm² and no more than 5 m long, a 150 A power-distribution switch, and a 70 mm² output cable no longer than 30 m.
The stated operating ambient range is -10°C to +40°C. Air inlets and outlets should remain unobstructed, and the machine should be protected from direct sunlight and excessive dust. Important procurement note: the supplied information contains conflicting specifications.
An overview section lists 67.9 kVA maximum load capacity, 40–1250 A current range, 85% efficiency, 790 × 465 × 800 dimensions, 87 kg weight, and a 60% rated duty cycle at 40°C.
The detailed parameter table instead lists 76 kVA rated input capacity, 30–1250 A, 80% efficiency, 690 × 365 × 690 mm, 85 kg, and a 100% duty cycle. It also separa primarily as a carbon arc gouging and arc welding machine.
These discrepancies should be resolved on the final technical datasheet and nameplate before purchase.
Before issuing a purchase order, confirm the required gouging duty cycle at the intended current, the applicable input-capacity figure, exact machine dimensions and net weight, rated output data, cable connector details, and whether the supplied torch and grounding cable match the planned installation.
Also confirm the exact transport packaging, because either a standard carton or plywood case is stated.
