High frequency aluminum welding.

In general 120 to 200 hz provides an ideal frequency for most aluminum welding. Setting the frequency from 120 to 200 hz provides an ideal frequency for most aluminum welding. 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.

The arc is enveloped by a stream of inert gas. 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.

Gtaw welding aluminum with alternating current high frequency gtaw welding aluminum with alternating current high frequency gas tungsten arc welding gtaw process utilizes heat generated by an electric arc maintained between the workpiece and a nonconsumable ungsten electrode.

If you have enough amperage an ac frequency setting of 100 120hz is a really good all around setting for most anything. The process works at the frequency of 250 hz. This video is about ac frequency adjustments and when to use different frequency settings. If you ve had trouble doing so here are the top 10 mistakes made while tig welding aluminum.

And here is another golden rule of thumb. For thinner aluminum or when doing build up on an edge of thin aluminum the higher ac frequency settings can be useful.
