1. Tie Joint

ILLUSTRATION 1 : Tied Joint
• Strip 7cm of Red Insulation Coating First on each end of the Joint.
• Strip 3.5cm of Clear White Contacting to Expose the Wire in the Inner Protective Coating 3mm thick.
• Tie Joint together to avoid loosening.
2. Solder Joint

ILLUSTRATION 2 : Soldered Joint
• Apply Soldering Paste to Tied Joint.
• Roll Soldering wire on to the joint area.
• SOLDER the Joint to avoid slipping out or loosening.
3. Apply 3.5MM-4.6MM HEAT SHRINK TUBING

ILLUSTRATION 3 : 3.5MM-4.6MM HEAT SHRINK TUBING
• Cover soldered joint with heat shrink tubing
4. Apply Electrical Insulation Tape

ILLUSTRAION 4: Use Electrical Insulation Tape
• Stretch and apply Standard Insulation Tape to cover joint
5. Apply AG-TAPE-HV

ILLUSTRATION 5: USE AG-TAPE-HV
• USE AG-TAPE-HV to Insulate Joint and after apply Electrical Insulation Tape to avoid it from rolling off since non-sticky.
6. Apply Heat Shrink Insulation 6mm

ILLUSTRATION 6: Heat Shrink Insulation 6mm
• Use Heat Shrink Insulation 6mm to protect AG-TAPE/HV FROM LOSSENING OR PEELING OFF
7. Apply AG-HOSE/96

ILLUSTRATION 7: AG-HOSE/96
• Use AG-HOSE/96 to cover entire joint from End to End
8. Apply 2xCable Tiers

ILLUSTRATION 8 : 2xCable Tiers
• Use two medium size cable tiers to secure both ends of the AG-HOSE/96 AS SHOWN ABOVE
9. Secure Joint to the tube

ILLUSTRATION 9 : Secure Joint to the Tube
Secure Joint plus excess High voltage Cable on to the Tube to Prevent it Touching/Earthing on the Machines Body for further Protection.
Notes!
• This format of Joining the LC-TUBE Red High Voltage cable does not exhaust the whole AG-TAPE/HV.
• The risk of it Short-circuiting or Earthing with the body of the Machine minimum and close to none.
• Joint as firm as you can even tug on the cable and does not Strip or Leak.
• Use of this format is much neater in appearance as well as very strong.
• Durable and Cost Effective, Less Power Leakage risk and also Water Tight
