DC 400.33UKP are new generation devices for professional semiautomatic welding with controlled spray transfer in an atmosphere of shielding reactive gases and their mixtures. These devices are irreplaceable for achieving minimal sputtering, full penetration and quality weld. DC 400.33UKP are known for their reliability and quality, incorporating the latest in electronics and specialty welding technology.

DC 400.33UKP is a high-capacity 400A inverter power source designed for:

  • semiautomatic welding with controlled spray transfer in an atmosphere of СО2. Controlled spray transfer mode.
  • conventional semiautomatic welding and deposit welding MIG/MAG mode.
  • usage as part of automatic welding apparatus.

The device is designed for use in combination with PM-4.33 feeding mechanism, as well as with feeders of other types.

  • Abrupt decrease of sputtering;
  • No metal deformation due to precise heat input control;
  • Full penetration and reverse roll;
  • Operation possible in any position;
  • Welding quality similar to that of argon arc welding with efficiency increased 3-5 times;
  • Current and voltage digital indication;
  • Supply mains and diesel-engine generator power.

Controlled spray transfer mode. Due to «drop by drop» metal transfer control DC 400.33UKP allows to reach a higher level of weld quality. independent current and wire feed speed control is achieved with the help of quick operating microprocessor and feedbacks, which allow to control and adjust arc parameters more than 1000 times per minute.

Controlled spray transfer technology helps to raise productivity, eliminate burn-throughs and lower edge preparation requirements.
This mode is used for root pass performance in pipeline welding. It ensures root pass with reverse roll in the process of indirect welding without backup plates.

MIG/MAG mode. Conventional welding mode with short circuits is characterised in DC 400.33UKP by high stability and «smooth» arc. Suitable for welding and deposit welding with both solid and flux-cored wire.
The device is perfectly suitable for root pass performance in the process of indirect welding. At the same time, semiautomatic welding is possible as well as welding with the help of automatic welding sets, such as UAST-1 apparatus (made by SPE «Technotron»). Reverse roll is guaranteed. Weld root formed has high mechanical parameters and good metallurgical properties. Welding with controlled spray transfer allows to avoid «pockets» in weld root and to weld light gauge metals in any position without warping.

PM-4.33 feeding mechanism is designed for solid steel, aluminum and flux-cored wire feeding from 0.6 to 2.4 mm in combination with DC 400.33 device or any other device with «strict» current-voltage characteristic.
