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.

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. The process works at the frequency of 250 hz. 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.

Https goo gl frdnss in part 2 of our aluminum basics series with weldtube we are talking about ac frequ. Frequencies between 80 and 120 hz are comfortable to work with increase control of the arc and boost travel speeds. 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. If you ve had trouble doing so here are the top 10 mistakes made while tig welding aluminum.

This video is about ac frequency adjustments and when to use different frequency settings. 1 newbies often forget to use the high frequency setting and set it to continuous. Subscribe for new videos every monday and friday. 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. And here is another golden rule of thumb. 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. In general 120 to 200 hz provides an ideal frequency for most aluminum welding.
