Product Description
ZX7-ST/STG Series IGBT Soft Switch Inverter Manual and Argon Arc DC Welding Machine (ZX7-200, 315, 400, 500, 630ST/STG)
The ZX7-ST/STG series IGBT soft switch inverter DC manual/argon arc welding machines include two major types: ST (manual/argon arc welding machines with contact arc initiation function), namely ZX7-200ST, 315ST, 400ST, 500ST, 630ST; STG (manual/argon arc welding machines with high-frequency arc initiation function), namely ZX7-200STG, 315STG, 400STG, 500STG, 630STG.
They come in various specifications with rated welding currents of 200A, 315A, 400A, 500A, 630A, and are a new type of efficient and energy-saving DC welding machine.
This series of welding machines can be used for welding carbon steel and low-alloy steel, and can also be used for welding metals such as stainless steel, high-alloy steel, copper, silver, molybdenum, titanium, etc. using argon arc welding.
Key Features:
1. Utilizes digital display, allowing precise current presetting and easy adjustments.
2. Employs IGBT soft switch inverter control technology for minimal IGBT losses.
3. Minimizes welding spatter, reduces welding distortion, and ensures excellent weld bead formation.
4. Achieves high load sustainability, enabling extended continuous welding.
5. Includes arc initiation current function for easy arc initiation.
6. Features thrust current function to prevent electrode sticking.
7. Offers argon arc welding capabilities with adjustable current decay during arc shutdown for aesthetic weld bead formation.
8. The ST model welding machine provides contact arc initiation functionality during argon arc welding.
9. The STG model welding machine offers a choice of contact arc initiation and high-frequency arc initiation for argon arc welding.
10. High efficiency, low idle power consumption, and significant energy-saving benefits.
11. Lightweight, compact, and easily portable, making it particularly suitable for field construction and high-altitude operations.
