Tool Specific Tips

AIR HEATERS
  • Heat transfer and element life depend upon good air flow: do not block the air flow by allowing a kink in the hose
BITUMAT
FUSION
  • FUSION 1: 
    • Do not operate the tool without supplied filters
    • Brushes should be replaced after 500 hours of service - we recommend sending the tool to our Repair Centre, due to the size of this tool brush replacement is more complex
  • FUSION 2 & 3C:
    • As recommended by Leister: weld at maximum speed. If this is too fast, then Leister recommends using 3mm instead of 4mm welding rod. This lowers the output. Maximum speed is not only better for cooling the gearbox, but also for the lifespan of the drive motor and the gearbox.
    • Do not operate the Extruder without the stainless steel filter as it is designed to protect element & motor from contamination.

  • How to Clean the Welding Shoe on an Extrusion Welder
  • The FUSION is not producing the correct heat
GHIBLI
Symptom: Bad welds or low air volume 
  • Check that the air intake at the blower handle is clear of dust and debris. Clean it with a soft brush to remove any blockage.
  • Check the air slide at the air intake. Turn it clockwise for more heat or counter-clockwise for more air volume.
GROOVER
  • Tool is not picking up debris or blowing smoke: Check that the blade is not on backwards.
  • Blade recommendations: ​Use the tungsten carbide tipped blade for linoleum and PVC flooring and the diamond cutting blade for anti-slip floors such as those that contain sand or quartz.
HEMTEK ST/K-ST
HOTWIND
  • The HOTWIND must be supplied with cool clean air or used with a filter: ​In particularly dusty environments or in environments where the impurities are very small, the filter should be covered with stocking material and checked from time to time to ensure it is not clogged. Impurities at the shaft bearings will cause noise and eventually prevent the HOTWIND turbine from turning at start-up.
SARNAMATIC
SARNAMATIC 661
  • Error 6 
    Occurs if the nozzle is in the welding position at power-up
    Also occurs if the power to the SARNAMATIC cuts out and comes back on while the tool is in use. Power will drop if there is a poor connection in the cord or plug, and due to overload or contaminated fuel when using a generator.

SARNAMATIC 641MC 
  • An error is displayed while the tool is cooling down 
    Answer: This is not a problem. Errors that come up while the SARNAMATIC is cooling down can be ignored.
  • Error 7 
    Occurs if the nozzle is in the welding position at power-up
    Also occurs if the power to the SARNAMATIC cuts out and comes back on while the tool is in use. Power will drop if there is a poor connection in the cord or plug, and due to overload or contaminated fuel when using a generator. 
  • Error 8
    Occurs if the heat is not turned off at power-up
    Also occurs if the power to the SARNAMATIC cuts out and comes back on while the tool is in use. Power will drop if there is a poor connection in the cord or plug, and due to overload or contaminated fuel when using a generator.
TRIAC
TWINNY 
  • TWINNY T - Error 100 after turning the heat on: Check that the blower is switched on.
UNIDRIVE
UNIFLOOR
Symptom: Bad welds or low air volume 
  • Check that the air intake at the blower handle is clear of dust and debris. Clean it with a soft brush to remove any blockage.
  • Check the air slide at the air intake. Turn it clockwise for more heat or counter-clockwise for more air volume.
UNIPLAN
UNIROOF 
VARIANT 
VARIMAT
VULCAN
  • VULCAN Tech Tips, includes:
    • Important wiring instructions
    • Cool-down instructions
    • Symptom:  After heating, tool will not cool down completely (VULCAN E only)
