Plasma welding is a welding method developed on the basis of tungsten argon arc welding. The compressed arc energy is more concentrated, the temperature is higher, and it has many advantages that tungsten-grade argon arc welding can't match.
1. High reliability, energy saving and consumption reduction:
This machine adopts IGBT full-bridge soft-switching inverter technology, which greatly improves the power supply efficiency and power factor. At the same time, it adopts peak current control technology and cooperates with overheating, over- and under-voltage, phase loss, water shortage and other protective measures to make the machine have High reliability.
2. Power adaptability:
The 3-phase input voltage can be safely used in the range of 260V-450V and can be used in different environments.
3. Simple operation, easy adjustment:
The panel parameter setting adopts single knob adjustment and menu selection mode. Make the welding operation easier and more convenient to use.
4. Strong applicability:
For ordinary welders you can save your settings or use welding experts' pre-stored parameters without any adjustments to complete high-quality welding. For those advanced users who require high welding, the system provides you with a very detailed description of the welding process. Control adjustments so that you can obtain welding output that meets your specific requirements.
5. Friendly man-machine dialogue interface:
The man-machine dialogue interface uses a combination of a digital display and a large-screen liquid crystal display to display the welding parameters in real time, which is intuitive and quick.
6. High welding efficiency:
For stainless steel and other non-ferrous metals with a thickness of 10 mm or less and low-carbon steels with a thickness of less than 8 mm, the small hole effect enables high-efficiency, one-sided, single-sided welding of double-sided molding without opening.
7. Welding torch design is unique:
The torch has a unique structural design, compact gun body, small size, light weight, good visibility, and low gas consumption. The torch is equipped with two types of clip-on and hand-held, and the handheld type can be welded in all positions, which is more suitable for on-site construction.

  Plasma arc welding and tungsten arc welding (TIG) are tungsten electrode gas shielded welding. However, plasma arc welding is restricted by the outside of the water-cooled nozzle of the plasma generator, so that the cross section of arc arc region is limited, so that the arc is integrated. The arc temperature and energy density increase significantly.
   Compared with plasma welding and argon arc welding, the depth of the weld pool is significantly increased, the weld heat affected zone and the deformation are small, the welding efficiency is high, the welding quality is good, and the welding energy consumption is low.
   Plasma welding is particularly suitable for the welding of stainless steel, titanium, copper, molybdenum, nickel and other non-ferrous metals and carbon steel.
