MINIFLOOR
Drive unit
Please read the Operating Instructions carefully before
use and keep them for future reference.
Hazardous voltage – danger to life
Life-threatening electric shock possible due to electrical voltage. The device is only
to be connected to sockets and extension cables with a protective earth conductor.
It must be protected from moisture and humidity. Prior to commissioning, check
the power cord, the plug and the extension cable for any electrical or mechanical
damages. The device may only be opened by instructed, qualified personnel.
Danger of fire and explosion with improper use of the hot air hand tool (e.g., material
overheating), particularly in the vicinity of flammable materials and explosive gases.
Risk of burning! Do not touch exposed metal parts while hot. Allow the device to cool
down. Do not point the hot air flow at people or animals.
Risk of entanglement! Fingers, hair, or items of clothing can be drawn in.
Warning

An FI switch is urgently required for personnel protection when the device is
used at construction sites.
The nominal voltage specified on the device must match the mains voltage.
If the network voltage fails, then the main switch and the drive must be switched
off.
Minimum overhead clearance with TRIAC AT is 295 mm.
Device is not permitted to be operated unsupervised. Heat can reach flammable
materials that are not in view.
Device may be used only by trained specialists or under their supervision. Chil-
dren are not permitted to operate the equipment under any circumstances.
Caution
Drive unit for the welding of floors with additionally available hot-air rod tools from Leister and Weldy, such as the
TRIAC AT.
Any use other than the use specified in 2.1 or beyond the intended use is deemed to be improper use.

• A minimum cross-section must be observed when
extension cables are used.
• The extension cable must be authorized for the utiliza-
tion site (e.g., outdoors) and be marked accordingly.
• When a power plant is used as an energy supply, the
following applies for its nominal output:
2 × nominal output of the hot air hand tool and fitted
with FI switch.
• Power plant must be grounded.

I. Align the hot air hand tool (22), rapid
welding nozzle (24),, and guide wheel
(3) with the welding groove.
If the guide wheel (3) jumps to the right
out of the welding groove during welding,
the running accuracy can be optimized
by turning the hot air hand tool (22)
clockwise. If the guide wheel (3) jumps
to the left out of the welding groove
during welding, the hot air hand tool
(22) should be turned counter-clock-
wise.
Set the required welding speed on the MINI-
FLOOR potentiometer (7).
Adjust the required welding temperature and
– if available – the air volume setting on the
optional hot air hand tool (22).
For the hot air hand tool (22) settings, please
observe the operating instructions of the
device in use.

Place the MINIFLOOR on the floor to be weld-
ed and swivel the hot air hand tool (22) into
the parking position. Unlock guide arm lock
(19).
Place the guide wheel (3) in the groove for
the welding rod. Switch the MINIFLOOR on via
the main switch (6).
Switch the hot air hand tool (22) on using the
appropriate switch.
Adjust the welding parameters for the heating,
and – if available – the blowers.
For the hot air hand tool settings, please ob-
serve the operating instructions of the device
in use.
Prior to commissioning, check the power supply cord (1), the plug, and the extension cable
for electrical and mechanical damage.
Switch off the MINIFLOOR (6) and hot air hand tool (22) main switches.
The nominal voltage, specified on the devices must match the mains voltage. Connect the device to
the nominal voltage.
In the event of power failure , swivel the hot air hand tool (22) into the parking position.
Do not point the hot air flow at people or animals.
Prior to commissioning, check the power supply cord (1), the plug, and the extension cable for
electrical and mechanical damage. Use extension cables with protective conductors only!
