Advanced features

High welding performance

  • High welding performance with solid or flux cored wire;
  • Built-in special welding data for metal cored wire, vertical welding of thin plates with small welding feet and beautiful shaping.
  • Bidirectional high-speed carrier communication technology

  • Greatly reduced disconnection breakdown with no control cable;
  • Significantly reduced cable weight for over-long-distance working;
  • Bidirectional high-speed Carrier communication technology between main power source and wire feeder makes information synchronization, precise welding control.
  • Dual frequecy carrier control technology

  • Adopting 250kHZ dual-frequecy carrier redundancy mode, it has strong anti- interference ability. Carrier frequency can be switched manually or adaptively.
  • Short circuit protection of carrier line

  • With carrier line short circuit protection function: can avoid PCB board damage caused by short circuit between carrier line and bus bar;
  • With automatic recovery function: after the short circuit between the carrier line and the base material is removed, the welding power supply can automatically return to normal state and continue working;
  • It also has protection functions against the following exceptions:
    / Carrier line and welding cable short circuit;
    / Motor control line short circuit;
    / The control line of solenoid valve short-circuit;
    / The welding torch switchabnormally short-circuit;
    / Collision of carrier line connectors;
    / Abnormal CT damage.
  • Adapt to harsh working environment

  • The PCB board and important parts are specially treated to be anti-corrosion and moisture-proof, suitable for high-temperature, humid and salt-spray environments in shipbuilding and offshore engineering.
  • First-level energy efficiency more energy-saving

  • The efficiency of the welding power sourcereaches 88%, and it has obtained first-leveenergy efficiency certification.
  • Optional IoT unit

  • Full digital communication interface and available for Ethernet, records welding data in real time and monitors the status of the welding;
  • Enables data exchange and analysis, remote downloading and changes to welding process specifications;
  • Automatically alarm when the welding current and voltage exceed the specifications. Complete welding tasks correctly and reliably.
  • Can identify IC card information and realize operator authority management and performance statistics ;
  • Both administer and user management are supported.
  • Upgraded cable connection interface

  • Easily switch between MMA/MAG/MIG/Gouge processes with wiring alone, realize multiple welding process requirements in one machine;
  • The special cable design supports tracheal carriers communication, reduces bulky cable obstacles, and reduces the failure rate of long-distance welding.

    Optimized separated wire feeder

  • 30% lighter than regular ones;
  • Good protection: Equipped with anti-collision side panels, and the top of the remote control is equipped with anti-collision side panels. reinforced design of wire reel shaft to prevent sagging and deformation;
  • Can provide powerful wire feeding force and good stability of welding;
  • Equipped with a full-featured remote control, which allows all parameters to be set at hand, making operation more convenient and fast.
  • Full function remote control

  • Full-function settings, from gas regulation to wire feed speed regulation, are not limited to simple current and voltage settings;
  • The JOB function can be called directly on the remote control, which is more collaborative;
  • Can lock the panel to prevent accidental touch;
  • The remote control can be quickly disassembled, so can take it anytime, anywhere to adjust the control.
  • Long distancewelding work

    Ultra-Long cable loop compensation function
    Intelligent compensation makes welding more stable, especially suitable for oversized workpiece welding occasions.
