Flashback arrestors on oxy-fuel welding rigs are most commonly located at the regulator. However, torch makers like Victor place them in the torches. Do any list members know if US OSHA has ever specified in writing where they must be located? Many say that placing them both at the regulator and torch is not good because it restricts gas flow too much.

Ps. Here in Tuxpan, Mexico we are just using them in the torch heads.
