ORBIMAT 300 AC/DC

ORBIMAT 300 AC/DC

 

Orbimat 300 AC притежава всички характеристики на продуктовата гама Orbimat C, но в допълнение може да предложи опция за АС заваряване. Това позволява на заваръчните глави на Orbimatic да бъдат използвани за работа с материали, които изискват променлив ток, за да бъдат заварени успешно. Всички функции са лесно контролируеми чрез показване на заваръчните нива на екрана.

Orbital Welding Power Supply ORBIMAT 300 AC/DC

 

The Orbimat 300 AC has all the features of the Orbimat C range, but in addition can offer an AC welding facility.
This allows the Orbimatic range of weld heads to be used an materials which require an alternating current to be welded successfully.
With adjustable AC Balance and Frequency to AC arc can be controlled to achieve the optimum weld profile for the application in hand. All functions are controllable on easy to understand weld level screens.

 

AC Arc Characteristics


When welding some materials it is advantageous to use an AC arc to aid the welding process. The most common material for use with an AC arc is Aluminium and it’s alloys. Aluminium Alloys form and oxide layer which has a very high melting temperature (above that of the aluminium). This means that when using a DC arc the oxide layer must be removed mechanically prior to welding. The cleaning process has to be very effective and very thorough and any trace of the
oxide will cause weld defects. When an AC arc this oxide is broken down by the alternation of the polarity. Therefore
the material will not need the substantial cleaning required with DC. The profile of the arc can be altered by the AC
frequency, this allows the operator to select a wide or narrow arc depending on the application. The profile of the weld bead can also be controlled using the AC balance facility. This function adjusts the shape of the wave form between negative and positive,
and therefore results in more or less penetration. By using a suitable combination of AC Balance and AC Frequency an optimum weld profile can be developed. This can be further enhanced by the range of different gas mixes available to suit particular applications and you should contact your gas supplier to discuss this with them.
