The outlet connector of the acetylene generator is damaged; the welder is using a connector made of red copper. Is this in compliance with the standards? Are there any accident cases in this regard?
It definitely doesn’t meet the standards; the safety performance of something homemade can’t be guaranteed. Especially when it comes to acetylene gas, one must be very careful. It’s better to buy a new one. .
No, it easily produces explosive copper acetylide.
Does acetylene react with copper to form copper acetylide?
This is a serious violation of safety procedures. Materials in contact with acetylene must be free of copper, as acetylene forms explosive metal acetylide compounds with many heavy metals. These non-compliant components must be replaced as soon as possible to avoid accidents.
I also checked some information just now, and it’s indeed as you said: acetylene readily reacts with heavy metals such as copper, silver, and mercury to form explosive acetylide salts, which can explode with just a slight impact. The safety regulations also stipulate that containers for storing acetylene must not be made of copper alloys with a copper content exceeding 70%, and silver-containing welding electrodes must not be used when welding with acetylene
This is common sense – unauthorized modifications are strictly prohibited. For more details, check the explanations and instructions provided above; they cover everything thoroughly. All you need to know is that copper acetylide is a highly unstable substance that is prone to explosions
