Resetting the day distance
The day distance can only be reset if the drive is switched off.

6.14 Key lock

The TWINNY T7 has a key lock. This blocks the four keys and the "e-Drive" (27) on the control panel (3). The
key lock is activated or deactivated by simultaneously pressing the "Up" and "Down" keys (22/23) for at least 2
seconds. When the key lock is activated, this is indicated on the status bar.

7. Commissioning the TWINNY T7

Your TWINNY T7 has "LQS" (Leister Quality System) – a function for recording welding data. This function logs the
speed, temperature, and welding force during the welding process along the welding seam length at predefined
distance intervals. You can find more information in the corresponding operating instructions at www.leister.
com.

7.1 Work environment and safety

The hot-air welder must only be used in the open or in a well-ventilated area.
Never use the hot-air welder in explosive or readily inflammable surroundings and maintain sufficient
distance from combustible materials or explosive gases at all times.
Read the material safety data sheet of the manufacturer of the material and follow that company's
instructions. Be careful not to burn the material during the welding process.
Power cord and extension cable
• The power cord (1) must be able to move freely and must
not hinder the user or third parties during work (danger of
tripping).
• The extension cables must be authorized for the utilization site
(e.g., outdoors) and be marked accordingly. Take into account
the necessary minimum cross-section for extension cables, as
required.
Power plants for energy supply
When using power plants as an energy supply, please ensure that the power plants are grounded and equipped
with residual-current circuit breakers.
For the nominal output of the power plants, the formula 2 × nominal output of the hot-air welder applies.

7.2 Setting the welding parameters

Connect the device to a socket with a protective conductor. Any interruption of the protective
conductor inside or outside of the device is not permitted. Only use extension cables with protective
conductors.
The nominal voltage specified on the device must match the local line voltage. If the line voltage fails,
switch off the main switch and swivel the hot-air blower into the park position.
