ZX7-140 Inverter DC arc welding machineDetailed product description：

The ZX7-140 inverter DC arc welding machine has super strong grid compensation capability, resistance to power supply voltage fluctuations, stable welding current, and reliable performance. The small DC arc welding machine adopts proportional thrust control technology, single button adjustment, and simpler operation.

The no-load energy consumption is less than 100W, which can save 50% of electricity compared to traditional welding machines.
The inverter frequency reaches 100KHZ, with high-speed dynamic response, easy arc initiation, stable arc, anti-interference, low noise, small splashing, deep melt pool, high strength, and good quality.
Good thrust adjustment, with anti sticking function of welding rods, suitable for welding various acidic and alkaline welding rods, and supports downward welding of cellulose welding rods.
Suitable for welding all black metals such as low carbon steel, medium carbon steel, and alloy steel structures, high-quality welds can be obtained.

Widely used in welding and field operations in industries such as oil pipelines, chemicals, automobiles, shipbuilding, boilers, power construction, nuclear power, aerospace, military, industrial installation, bridge construction, etc.
