Gday fellas,

Iím new to MIG welding (never even attempted), bought all my gear to get started (unimig viper 185).

Hoping to lay some beads and practice this arvo went and got a size E argon/co2 bottle from Bunnings but when I connect the reg to the bottle I get no gas flow at all. Itís as if the fitting isnít long enough to depress the little safety pin thing in the coupler on the bottle (pics attached)

Am I doing something wrong or did I just get really unlucky and get a dud bottle first time round?
