Operating your Sealer
Assembly Instructions
Sealer comes assembled and ready to operate.
Operation
1. Before operating, check the heating element, PTFE cover, PTFE adhesive and the
silicone rubber. The heating element should be intact.
2. Insert the power cord into the correct receptacle (110V).
3. Turn the power switch on.
4. Set the timer knob to the lowest setting. Always start with a low setting and increase gradually as
needed.
5. Place material to be sealed on the base of the sealer and bring the sealing arm down firmly, but
gently. The red light will turn off when sealing time is complete.
6.
When red light turns off, keep pressing the sealing arm down for an additional 2-3
seconds. For a high quality seal, seals must cool under pressure. We usually recommend
a congeal setting of at least 2x that of the heat setting but every bag will have variations.
Thicker materials will require a longer cool (congealing) time.
7. For units with a sliding cutter, slide the cutting bracket across poly material to cut material above
the seal.
Tips for Successful Sealing
1. If the seal is broken or damaged, decrease the sealing time.
2. If the seal is not fully welded, increase the sealing time.
3. If the sealing material sticks to the sealing pad, decrease the congealing time.
4. If the width of the seal is not perfect or does not match the size of the element, increase the
congealing time.
When sealing/timer light turns off, keep pressing the sealing arm down for
an additional 2-3 seconds. For a high quality seal, seals must cool under pressure. We
usually recommend a congeal setting of at least 2x that of the heat setting but every bag will
have variations. Thicker materials will require a longer cool (congealing) time.
5. Always keep the sealer clean. Remove any residue found on the platform and PTFE cover. Silicone
spray may be used for this purpose.
