High Frequency Aluminum Welding

For thinner aluminum or when doing build up on an edge of thin aluminum the higher ac frequency settings can be useful.

High frequency aluminum welding.

This ends up causing the machine to stall at low amperage since the alternating current loses most of its half cycles when the flow of the current is changed. By spending less time at each polarity the arc cone has less time to expand. 1 newbies often forget to use the high frequency setting and set it to continuous. Frequencies between 80 and 120 hz are comfortable to work with increase control of the arc and boost travel speeds.

This video is about ac frequency adjustments and when to use different frequency settings. If you have enough amperage an ac frequency setting of 100 120hz is a really good all around setting for most anything. Setting the frequency from 120 to 200 hz provides an ideal frequency for most aluminum welding. Therefore we have developed high frequency linear friction welding hflfw in which a higher frequency than in the case of conventional lfw process is used with the aim to weld high thermal conductivity materials such as aluminum alloys.

In general 120 to 200 hz provides an ideal frequency for most aluminum welding. If you ve had trouble doing so here are the top 10 mistakes made while tig welding aluminum. The process works at the frequency of 250 hz. And here is another golden rule of thumb.
