CONTACT TIP REPLACEMENT
Each application will dictate the frequency of contact tip replacement. Higher amperage higher duty cycle operations will require more frequent contact tip replacement. The condition of the contact tip greatly effects the welding performance. A routine tip replace- ment schedule should be established and adhered to. For general operations contact tips should be changed at the beginning of every shift.
LINER REPLACEMENT
Wire condition and plant environment as well as wire consumption rate dictate how often a liner should be changed. Smaller wire diameter will require a more frequent change interval than large diameter opera- tions. For general operations using .045" dia. wire lin- ers should be changed after approximately 2000 lbs of wire use.
