  • Overvoltage protection
  • Under voltage protection
  • Phase detection protection
  • Thermal protection

Common uses

The Cruxweld CSW series SAW welder is suitable for heavy-duty longitudinal structures such as girders, and I-beams welding applications where high deposition rates and welding productivity are required. It is an ideal choice for butt welds, fillet welds, and double V joint welding of plates required for the shipbuilding industry, railways, bridge construction, earthmoving equipment components, etc.

User-friendly controls

Digital display, wire inch pushbutton, OCV test button, set/weld switch, carriage ON/OFF, UP/DOWN switch, voltmeter/ammeter, and carriage speed settings on the control panel. Facility to check carriage speed and OCV before the welding procedure begins.

Features and Benefits

  • Field-proven, easy-to-use interface.
  • The power source is CC-CV type and suitable for MMA/ GOUGING and SAW welding processes.
  • Suitable for a wide range of metals such as carbon steel, stainless steel, aluminum, and their alloys, using appropriate or recommended consumables.
  • Compensate for ±15% input voltage fluctuation to maintain welding consistency.
  • The built-in thermostat protects against current overload and overheating.
  • Proven reliability in heavy use – IP23 certified to withstand harsh environments.
  • Voltage Input 380 – 575 VAC, 50/60Hz – Provides universal compatibility.
  • The welding hopper has a sufficient capacity (10 kg / 7 liters) to ensure long and uninterrupted welds.
  • The high power factor correction rate of 95%, as well as the energy-efficient design, result in significant savings in power consumption compared to traditional transformer-based equipment. 
  • Advanced control of welding speed and penetration improves welding speed, weld quality, and efficiency.
