LAB 4000
Heavy Duty Semi-Automatic MIG / MAG Welding Equipment
LAB 4000
are power sources of high efficiency constant voltage stepless control designed for MIG (aluminum, copper), MAG (carbon steels), and Cored Wires with gas-shielded protection or self-protected.
  • High efficiency power source with constant voltage characteristic
  • The sets are composed of power sources of constant voltage that provide great stability of the arc
  • Operate in Short-circuit, Globular and Spray transfers
  • Servo-III wire feeders allows linear speed control to a max of 22 Meters / Min
  • Variable inductance for welding in short-circuit (CO2 or mixture) minimizes the occurrence of splatter and makes the opening of the arc easier
  • Digital voltage and weld current display keeps the values after the welding
  • Continuous adjustment of the arc voltage (without plugs or switches) assures broad range of control for a better arc stability
  • Efficient cooling system assured by powerful fan
