Purpose of the development: Unit (inverter type welding rectifier) is designed for manual arc welding with coated electrodes (MMA) and TIG (TIG) neplavjashchimsja (tungsten) electrode (when connecting gate (TIG) torch) steels, copper alloys, titanium (except alloys aluminum-based). The method of ignition arc TIG welding - pin.

Recommended application field: The machines are intended for professional use. Specifications require intensive use of its production processes - construction, repair and assembly operations.

Advantages over analogues: Application of advanced inverter technology reduces the weight and size of the equipment, increase efficiency up to 82%. High-quality materials ensure complete reliability, ruggedness and ease of maintenance.

The development stage readiness: Introduced in production

Description of the development:
()
In tests based on PWI . EO Paton source showed a high degree of reliability and confirmed all the specifications declared by the manufacturer - Hutong ® PRC. This device allows welding DC using inverter technology conversion and control of welding current on the basis of powerful IGBT transistors ( IGBT gate ) with a conversion frequency - 100 kHz. Applying the principle of pulse width modulation (PWM) provides a convenient and accurate control of the welding current , stability and arc stability . The device has a built-in automatic thermal protection and protection against voltage skachkopitayuschego . When protection indicator lights on the front panel , the welding current is stopped , while the cooling fan continues to run. Turning off the indicator means that the device is ready for further work. The device was designed, manufactured and tested with the latest European requirements. Options: - 3 m cable with Electrode ; - 3 m cable with a ground terminal ; - Power cord length 3 m Models have the technical options : - "Hot start" ( hot start ) - designed to facilitate arc excitation by short ( 0.01 ... 1 s) increase the strength of the current with respect to the base value of the regulated welder . After the time arcing stabilized and current hot start gradually decreases to baseline current. Allows you to immediately ignite the arc and immediately start welding . Facilitates arc ignition when working in awkward , narrow and hard to reach places . Occurs more intense (faster ) heating the electrode tip and accelerated formation of the weld pool , as well as allows the welder to ignite the arc , without " sticking" of the electrode. - "Antistick" ( antizalipanie ) - ( sharp decline in the welding current electrode is stuck ) . This function prevents the electrode sticking to the welded parts , prevents it from overheating .
