Features

I. LSA (Low-spatter Arc for MAG / CO2)

Optimized and upgraded based on standard synergic MIG/MAG, through software-based precise control, the molten droplet of short-circuit transfer is softly disconnected, so that the spatter caused by the traditional liquid bridge explosion and electromagnetic repulsion is reduced. The molten pool is calmer, and the weld formation is more beautiful.

Process Characteristics:

• Accurate in software control for high-frequency short-circuit transfer. Lower in spatter. Lower in heat input. Highly suitable for sheet metal welding
  

• Soft in welding arc and fine with spatter particles. Less spatter to remain on the workpiece. Lower with rework like grinding after welding. Higher total working efficiency

• Higher in welding speed. Better in deformation control. More helpful in welding quality
  

II. QPT (Short-arc pulse)

The industry-leading 180 K HZ inverter frequency brings the advantages of high-speed sampling and control. Dex can find critical control and balance between short-circuit and spray transfer and achieve higher transfer speed.

Process Characteristics:

• Low spatter, low heat input, suitable for high-speed sheet metal welding
  

• 50%~100% faster than the standard pulse MIG/MAG process
  

• Less sensitive to shield gas composition. Capable of welding SUS solid wire with a mixed gas of 80% argon / 20% CO2
