1.2. Pulsed source with digital control POWER WAVE 455 – description

Welding source POWER WAVE 455 in connection with feeder POWER FEED 10 represents new designing trend in solving the top, digitally controlled invertor sources for GMAW, SMAW welding in heavy – duty industrial conditions. New characteristic feature of this design is control of this source and feeder from one control panel on the feeder POWER FEED 10. Controlling information for the source are coming into the source POWER WAVE 455 from the feeder POWER FEED 10.

The source enables both, the flat setting (CV) and steep setting characteristic.
Therefore it is possible to use it for the following methods:

• GMAW (MIG/MAG)
• SMAW (manual welding with coated electrode)
• GTAW (TIG)
• gouging with carbon electrode

Arragement of control panel on feeder POWER FEED 10 is variable, according to requirement of customer – enables to equip this source with simple CV characteristics for GMAW (MIG/MAG) welding, but also for pulse welding with possibilities of individual interference into the welding charasteristics. This source can be also provided with a small panel for the possibilities of welding parameters storage into the six fixed and two variable memories. Selection of parameters from these memories is possible from the control panel or through the change-over switch on the welding gun. Change of program is possible during the operation of the source, so that the operator can prepare in advance two sets of welding parameters. In the course of welding he can choose which of them he wants to use.

This source offers to user a range of installed synergic curves for unalloyed materials, highalloyed materials, aluminium and its alloys with silicon or manganese and tubular wires. Synergic curves are available for both, pulse welding and non-pulse welding.

The selected system of control is easy to understand, so that only short time for training of an oparator is needed.The controlling electronics and microprocessor control are situated under the feeder control panel and do not bother the oparator in any way with too great number od values.The customer selects the optimal configuration of individual elements (panels, interconnecting cables and other accessories) to suit his purpose and his particular needs.

Another suitable element for users is the possibility to separate the control panel from the feeder, the feeder can be located separately, for example into the existing automatic welding equipment and in the same way the control panel can be placed into the control panel of the existing equipment. The welding source can be located independentally, length of all interconnecting cables is selectable.

POWER FEED 10 is a new type of welding wire feeder. It contains complete control circuits and controls for setting of the welding source POWER WAVE 455. Its totally different design, compared with feeders used until now, is a new trend in the field of highly reliable and powerful wire feeders with an advanced system of control, operation without maintenance and easy change of the total arrangement of the feeder to meet all needs and requirements for this work.

The new design of feeding mechanism does not require for its attendance and maintenance any tools – replacement of rolls and cleaning. For speeding of work the feeder POWER FEED 10 is provided with an automatic guiding of wire.
