High Frequency Aluminum Welding

This is part 3 in a how to tig weld aluminum series.

High frequency aluminum welding.

If you ve had trouble doing so here are the top 10 mistakes made while tig welding aluminum. Hitbox tig welder ac dc pfc wide voltage 65 265v 200a pulse tig stick 4 in 1 multifunction high frequency iron aluminum tig welding machine 4 2 out of 5 stars 10 899 99 899. If you have enough amperage an ac frequency setting of 100 120hz is a really good all around setting for most anything. The arc is enveloped by a stream of inert gas.

In general 120 to 200 hz provides an ideal frequency for most aluminum welding. Https goo gl frdnss in part 2 of our aluminum basics series with weldtube we are talking about ac frequ. 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. 1 newbies often forget to use the high frequency setting and set it to continuous.

Increasing frequency above 60 hz causes the current to change direction more often which means that it spends less time per cycle in both dcen and dcep mode. And here is another golden rule of thumb. This video is about ac frequency adjustments and when to use different frequency settings.

For thinner aluminum or when doing build up on an edge of thin aluminum the higher ac frequency settings can be useful. Setting the frequency from 120 to 200 hz provides an ideal frequency for most aluminum welding. 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. By spending less time at each polarity the arc cone has less time to expand.
