Welding thin aluminum with a short pulse is possible, but not an easy task. If I come up with a good idea in the future, I will make a related video.

Possible, with some limitations. The procedure shown here uses a regular TIG set-up in pulse mode. My machine allows me to set pulse width to 1% of the period. That is only convenient when welding simple shapes (flat or circular). With more complex shapes requiring precise positioning, I don't want to be forced into a cycle. For that, I use a torch with a gas valve in the handle and this pulse generator: www.ebay.com/itm/283969229999 Independent argon feed is important because accurate millisecond-scale timing is not possible on top of at least 1 second of the shortest pre-flow. Disabling the pre-flow altogether and feeding argon straight from the bottle allows the machine to respond to pulses in the trigger circuit. That method is not without problems because of other delays in the trigger that still happen when pre-flow is disabled; the delays may appear random because the trigger is synchronized to the AC power while the pulse generator is not. So it is not possible to send accurate 10ms pulses; by setting pulse duration to about 200ms, I get 10 .. 30ms arc pulses; the longer the driver pulse is, the more accurate is the arc timing. The minimal pulse length at which my machine responds reliably is around 190ms. I do get pretty good results with this set-up.

Some welders have a suitable spot weld function. However if you have a good pulse function (a more common feature) you can do virtually the same thing. Set up a high-amp narrow pulse (maybe 10-15% on time), at about 1 per second. Low background current, about 10%. The arc doesn't go completely out and the gas doesn't shut off so no problems with pre-post flow. There are some videos of that here on KZfaq.

@@benz-share9058 I use pulse regularly but never tried it like that sounds like it should work will give it a go thanks.

가능은 하지만 정직한 방법으로는 쉽지 않습니다. 속임수 한방울이 필요할수도 있습니다

Las configuraciones utilizadas en el video son soldadura en frío de repetición automática, no configuraciones de pulso. Tienes razón en que se usaron 100 amperios.

아니에요 ㅎㅎ 이렇게도 해보고 저렇게도 해보는 거에요. 여러가지 해보고 좋은 방향 찾아볼려구요
