Change welding gap in routing pipes after being set.

Hello to Everyone,

I would like to know if there is a way to change the welding gap for routing after being set. I have this question because I made the complete route and realize that the welding gap was to big (5mm) and I would like to change to 1mm or 0.

I tried trough change properties but it doesn´t apper in options so if there is sombody who may help me, please.

Thanks in advance.
