By spending less time at each polarity the arc cone has less time to expand.
High frequency aluminum welding.
This is part 3 in a how to tig weld aluminum series.
For thinner aluminum or when doing build up on an edge of thin aluminum the higher ac frequency settings can be useful.
In general 120 to 200 hz provides an ideal frequency for most aluminum welding.
And here is another golden rule of thumb.
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.
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.

The process works at the frequency of 250 hz.
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.
Setting the frequency from 120 to 200 hz provides an ideal frequency for most 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.
If you have enough amperage an ac frequency setting of 100 120hz is a really good all around setting for most anything.
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.
If you ve had trouble doing so here are the top 10 mistakes made while tig welding aluminum.
