VARIMAT Family Tips

• Working with generators
• Never turn the generator on or off with the VARIMAT on: this may cause surges which can cause damage to the VARIMAT. Always make sure the VARIMAT is off before turning its supply generator on, and always turn the VARIMAT off before turning the generator off.
• When using a generator, ensure that the maximum current capacity is never reached: In that condition, voltage spikes can damage equipment.  If the generator begins to roar, it may have reached its maximum capacity.
• Dirty or water-contaminated fuel, undersized generators or poorly maintained extension cords can cause spikes in the power to the equipment which may blow fuses or damage circuit boards.
• The minimum generator capacity required when using only a VARIMAT is 6000W with at least 5000W of continuous output. However, if a 120V hot air tool will be used simultaneously a 10,000W or higher rated generator is recommended.
  
  
• Symptom: Bad tracking, membrane burns, folds 
• Check if the nozzle is too far under the drive tire, contacting the green belt and lifting one of the rollers in the hold-down assembly.  The nozzle should not touch the green belt or roller since this interferes with the placement of the membrane and the flow of air. In welding position the inside edge of the nozzle opening should be 1 - 2 mm. outside of the drive tire, with the rest underneath.  The edge of the nozzle should be 4 to 5 cm. away from the bottom edge of the drive tire.  
  
  
• Symptom: Temperature is not steady, it floats up and down 
• Check that the ground pin (the pin with the 90 degree bend) on the plugs of the VARIMAT and any extension cords used are connected to the ground wire.  They may be either loose or pushed too far in so that the screw is clamping down on the insulation and not on the wire.  If the ground is not connected the temperature can float up and down. 
  
  
• The lock pin may snap if shock or extreme pressure is put upon the ELECTRON blower while it is locked in the upper position.
• The most common reason that a lock pin breaks is if the VARIMAT is picked up with one hand on the blower handle when the nozzle is in the upper position. When lifting the VARIMAT, hold it by the T-Grip and frame only.
