Description

Description

The DDT welding machine uses inverter technology and welds with coated electrodes up to 4 mm in diameter. The current is continuously adjustable from 20 to 300 A, while Hot Start makes arc ignition easier and Anti Stick helps prevent the electrode from sticking.

Forced fan cooling helps maintain a stable temperature, while thermal protection automatically shuts the machine off if it overheats. The machine supports single-phase power and has compact dimensions for easy hand carrying.

  • Type: MMA
  • Inverter technology: IGBT
  • Welding current: 20–300 A
  • Duty cycle: 60%
  • Electrode diameter: 1.6–4 mm
  • Supply voltage: 230 V
  • Power: 12.5 kVA
  • Efficiency: 90%
  • Functions: Hot Start, Anti Stick
  • Cooling: Forced air cooling
  • Protection: Thermal overload protection
  • Package contents: 1.3 m earth cable with clamp, 1.8 m electrode cable with clamp, wire brush with slag hammer, basic welding mask, carrying strap, manual in Romanian
