Description

The welding machine is designed to withstand years of use under the most difficult conditions. It can be used in any environment: professional, semi-professional, and hobby. The brand DDT PROFESSIONAL that belongs to this welding machine is top-notch and produces equipment capable of handling intense use, as well as tasks that require finesse. All welding machines have been tested before hitting the market and their lifespan spans several years.

With this multifunctional machine designed for welding metallic structures made from ferrous and non-ferrous metals, welding is carried out using a coated electrode with a diameter of up to 4 mm, both in direct current and alternating current. The current setting ranges from 20A to 300A. The inverter is economical and includes a short circuit and overload protection device. The welding inverter of this model features a built-in fan that ensures temperature stability. In case of overheating of the machine, an automatic shut-off is activated.

Functions such as light arc start, arc stability adjustment during welding, and an anti-stick function for electrodes significantly extend lifespan and improve welding quality.

Features:

  • Latest generation IGBT technology.
  • Compact size.
  • Forced cooling.
  • Overheating protection.
  • Electrode ionization.
  • Hot start.
  • Low idle losses.
  • Quality of the core component.
  • Smooth welding current adjustment.

Functions:

  • Anti Stick.
  • Overheating protection.
  • Welding current adjustment.

Advantages:

  • Single-phase supply 230V ±15%.
  • Small size, reliable and durable, easy maintenance.
  • Welding with all types of electrodes.
  • High stability of the welding current with variations in the supply voltage.
  • Continuous welding current adjustment.
  • Intensive working mode (semi-industrial 60%).
  • Modular internal architecture meaning increased reliability and long lifespan.
  • Forced ventilation.
  • Thermal protection with thermostat.
  • Can be powered by a generator, due to the source supporting voltage variations ±15%.

Output current adjustment (A): 20 - 300.

Duty cycle: 60%.

Efficiency: 90%.

Absorbed power (kVA): 12.5 kVA.

Supply voltage: 220 V.

Fast connector: 10-25.

Electrode diameter: 1.6-4mm.

Included accessories:

  • 1 x Ground cable 1.3m.
  • 1 x Electrode cable 1.8m.
  • 1 x Hammer and brush combo.
  • 1 x Simple welding mask.
  • 1 x Carrying strap.
  • 1 x User manual in Romanian.
