6. Maintenance
The complete machine should be cleaned, greased and placed in a dry place if it is not used.
For PVC welding, the adhesions on hot wedge should be cleaned off if it is not used longer than 4 hours to prevent wedge corrosion and service life being
shortened.
Recommend: for welding of material that corrosive gas may be produced after hot fusing such as PVC and the like, stainless steel hot wedge (optional
accessory) is preferred for extending of service life.
