so you reccomend that i let it run for a little bit to warm up the tail pipe. anything else??

So i increased the length of the tail pipe from 22cm to 77cm and i managed to get two separate bangs from it but nothing more. im not sure what im doing wrong..

Hey all, im a student and i am trying to learn to tig weld both steel and aluminium and i cannot get the settings right on the welder to make the metal join or the weld to look of quality. please help cause i really wanna get this to work

Ive built this pulse jet at my school work shop and was testing it today and i couldn't get it to start. im not sure what im doing wrong. it runs on propane and then i use a small leaf bower to try and start it. i cant seem to get it going. any help would be so helpful. heres a video of the test run...
