Care and maintenance
Caution: At the time of repair works on the equipment, pull out the mains plug.
•
Never clean the welding area with a liquid.
•
Use only original spare parts and replace these parts punctually for a long service life of the
equipment and the best results over a long-term.
•
Worn out silicone rubber (6) can adulterate the welding seam. Please replace it if it becomes
burnt or worn.
•
Replace the damaged Teflon. The upper and lower Teflon must always be changed together.
Damaged Teflon tape, especially the lower piece, can lead to a short circuit.
•
When you replace the heating wire, also check the state of the Teflon tape. If it is damaged,
replace that as well.
•
Only heating filament specially supplied for this type of equipment may be used. Other hea-
ting filaments can destroy the transformer.
•
Always keep the welding area clean. Film residues can shorten the service life of the welding
wire, the Teflon tape and the silicone rubber.
Changing wearing parts
1. Loosen both the metal plates (5) on both the sides of the equipment.
2. You can now take off the upper Teflon tape (6).
