Do not attempt to relight the torch until the source of the flashback is identified and resolved. Inspect the equipment for any damage before resuming welding.

6. Are flashback arrestors necessary for all welding operations?

Yes, flashback arrestors are highly recommended for all welding operations where a fuel gas, such as acetylene or propane, is used. Flashback arrestors provide an additional layer of safety by preventing flames from traveling back into the gas supply line, reducing the risk of a potentially dangerous situation.
