Function:

PDG 402 Welding Semiautomatic Machine is designed for shielded (CO2 or Argon) arc welding of metal structures of carbon, low-carbon, alloy, low-alloy or corrosion-resisting steel using electrode or special flux cored wire.

Field of Application:

Metal structure production from metal plates or metal shapes, machine building, shipbuilding, gas processing or petroleum refineries.

Welding machine control unit provides:

• welding sequence automatic control;
• dynamic going up of motor when switched on, and dynamic slowdown when switched off;
• electronic protection of motor from overload;
• manual switch-on of gas blow-off and wire feed at setup;
• manual setting of wire feed rate and its stabilization;
• three welding methods: long seams, short seams, or spot welding (tack weld);
• spot welding (tack weld) time regulation;
• weld zone gas blow-off duration setting – before and after welding;
• arc spread time setting;
• welding machine switch-off if overheated, with alarm buzzer;
• digital display of different parameters.
  

Welding rectifier details:

• arc voltage (welding current) continuous adjustment;
• SCOMES rectifier assembly – with overheat or overload protection;
• two levels of inductivity;
  
• ~ 36 V supply voltage for shielding gas heater;
• retractable platform for a gas cylinder.

Wire feeder details:

• four roller feeder with 65 W motor by TBi Industries and gearwheel;
• welding machine control unit built-in;
• slow-down device by TBi Industries that prevents welding wire from self-detwisting (designed for wire spool holders of up to 18 kg capacity).
