Brilliant idea ! If thin aluminum sheet TIG welding is tricky, add this set up !

캔에 얇은 막을 사포로 문질러서 제거하고 하시면 용접이 수월해져요

텅스탠이녹는대 이유가뭘까요

Why are you using pulse? If that's your only option, try 33 rule. 33% background 33% time on, 33 pulses per second. Then set it around 1.1 amps per thousandth of an inch.

@@InchFab To improve my heat control skills I made some thin and small aluminum coupons. Heat builds really fast and you have to be good with the pedal or 4T, or the weldment will melt away. I experimented with slow pulses (once/sec) and higher duty cycle (60-70% high current time) to give some time to step forward while building up less heat. Works ok but not a big benefit so far. Thin+small aluminum (nowhere for heat to go) is good, demanding practice!

More experiments have shown me that our welding brother here on RU-vid has the best solution in this video. Narrower pulses (20-30%) are better to reduce heat input. Wider/longer pulses make it easier to step forward and insert the rod at the right time, but they increase heat input, so the wider pulses are not a good idea.

Of course, foot pedals are nice too, but they are not sold in South Korea.

Я приглашаю вас в Азербайджан, с работой тоже помогу. Сам тоже сварщик.

@@husterhanter6965 Salam. Sizcə videoda həqiqət var ? Məndə aparat 315 amperdir. Mümkün deyil, əridir metalı.
