• When welding some materials it is advantageous to use an AC arc to aid the welding process
• Most common material for use with an AC arc is aluminum and it’s alloys
• Aluminum alloys form and oxide layer which has a very high melting temperature (above that of the aluminum). 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
