Operating manual (Translation of the Original User Manual)
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
1. Important safety instructions
You can find more information on the MINIFLOOR at www.leister.com
Congratulations on your purchase of the MINIFLOOR.
You have chosen a first-class welding machine.

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.

6. Operating readiness
A. Push rubber band (15) onto the clamp-
ing device (16) according to the diame-
ter of the hot air hand tool (22) handle.
When using a Triac PID hot air hand tool,
a Rubber band (15) 155.153 must be
cut to size in accordance with the sketch.

B. Place hot air hand tool (22) in clamp-
ing device (16) and tighten with a
clamping screw (2).
Make sure that the hot air hand tool
(22) sits in close alignment with the
clamping device (16).
C. Insert 5 mm tubular nozzle (23),
100.303 and rapid welding nozzle
(24) 105.433 for wire diameter of 4
mm or 105.432 for wire diameter of 3
mm (make sure that the tubular nozzle
and rapid welding nozzle are correctly
aligned).
Caution: Welding with bent tubular
nozzles (24) may lead to poor welding
results!
D. Connect the hot air hand tool (22) to
the outlet on the MINIFLOOR (18).
E. Roll up the cable for the hot air
hand tool (22) and attach to the ap-
propriate openings (8) on the cover
plate (13) with a hook-and-loop
fastener (21).

H. Inspect the position of the adjusting
screw for the starting switch (20).
Meaning:
• Reduce start delay (−)
• Delay start (+)
Default setting ex works:
The middle groove of the setting washer
for the starting switch (20) is aligned
to the bottom edge of the guide arm (4).
F. Insert the unwinding device (11) into
the hole (10) and fasten it in place with
the clamping screw (12).
G. Alternatively, without the unwinding de-
vice, guide the welding rod through the
lug (17).

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.
