Start with the welding or cutting process
First separate the requested parts into MIG/MAG, TIG or plasma cutting families. MIG/MAG torch consumables commonly include contact tips, tip holders, diffusers, gas nozzles, torch liners and swan necks. TIG torch assemblies use parts such as ceramic cups, collets, collet bodies, gas lenses and back caps. Plasma front ends may include electrodes, nozzles, swirl rings, shields and retaining caps. Similar color or shape does not prove that two parts belong to the same system. Record the process shown on the existing package, equipment document or purchasing record before comparing individual components.
