those foam are not actually white foam. those are made from glass particle and fireproof materials. see the full video you can understand. thank you

Thank you

Here 4 simple diode (u can use any diode) and 1 22v zenor diode i use . Tnx for ur question

Actually I am far away from home now, I will try to show it in a video when I return home after a few days. Sorry for the delay. Thanks for comment

@@hq991ok muito obrigado e fico no aguardo do video

@@hq991vc conseguiu fazer o esquema elétrico

Yes

@@hq991 amigo eu fiz como no diagrama mas a ponte de diodo e o triac estourou

Not working

it is breaking down repeatedly 15w1k

perdon por la demora señor En realidad, la soldadura de aluminio requiere corriente alterna y corriente continua cuando desea soldar acero, cobre, etc. Dado que de este circuito obtendrá CA CC en dos tipos de corriente en la sección de salida. Si obtiene tanto CA-CC como corriente de salida, puede soldar cualquier cosa como aluminio, hierro, acero, cobre, etc. El hierro, el acero y el cobre son fáciles de soldar con corriente continua, pero el aluminio es difícil de soldar. Para eso necesita corriente alterna Pero no solo corriente alterna, necesita una corriente alterna balanceada. Mira bien el vídeo de principio a fin y lo entenderás.

sorry for the delay sir, Actually aluminum welding requires AC current and DC current is needed when you want to weld steel , copper etc. Since from this circuit you will get AC DC in two types of current in out put section. If you get both ac-dc as output current then you can weld anything like aluminum, iron, steel, copper etc. Iron, steel and copper are easy to weld with DC current but aluminum is difficult to weld. For that you need AC current But not just AC current, you need a balanced AC current. Watch the video well from the beginning to the end and you will understand.

​@@hq991Hello, can you tell me the size of the big choke and the wire thickness?

No sir. I'm uploading a new today on this, plz see this video. Thanks for your question.

@@hq991 muchas gracias por su respuesta., ¿y a que tipo de maquina se conecta a ac o dc?

sorry for the delay sir, i was busy to complete editing of my next video for 4 days. this is actually a transformer based ac stick welder and modify this into a ac dc tig welder by the help of this arc starter circuit and because this a ac welder so in terms dc you have to use a 200amps bridge rectifier.

What do you mean by 8 pins? If it is flyback pins then answer is yes. We need only 4 pins that is primary and secondary.

No

No sir
