- Model 50 DC - For Manual Applications with Low Welding Currents



Micro GAP 50 DC is ideal for welding applications that require precision, high-quality layer quality and low dilution; in particular when fully automatic welding is impractical or inapplicable due to low numbers or the diversity of the tasks. The welding units are available with various features. The operation is carried out via push button selector switches and knobs on the front display. Micro GAP 50 DC is designed for manual and semi-automatic welding tasks in which frequent parameter changes are required. All the settings are displayed on the LCD display in plain text, and up to 100 memory locations are available for storing the welding parameters. The extremely powerful inverter delivers 33 A at a 100% duty cycle, which is also sufficient for micro-plasma welding.

  • Plasma welding, plasma spot welding, TIG welding
  • Clearly laid-out control panel
  • Simple pre-selection of the welding parameters
  • Compact design
