Key specifications

Selecting the right option

Liner bore must suit the wire diameter — too loose and the wire wanders; too tight and it drags. Steel liners handle mild and stainless steel wire; Teflon liners are required for aluminium and silicon bronze. Match the liner length to your torch — a liner that's too short won't seat properly and will cause feed problems.
