Commissioning your UNIROOF 700/300

6.1 Work environment and safety
Health risk
Welding PVC materials creates harmful hydrogen chloride vapors. The hot air welder should be used
only in well-ventilated indoor areas.
Read the material safety data sheet from the manufacturer of the material and follow that company’s instructions. Be careful not to burn the material during the welding process. The danger of fire and explosion
Never use the hot-air welder in explosive or readily inflammable surroundings. Maintain sufficient distance from combustible materials or explosive gases at all times.
Caution
The device should only be used on a horizontal (roof slope up to 30°) and fireproof support.
Caution
Comply with national statutory requirements regarding occupational safety (securing personnel or devices).
Anti-fall protection when working in areas where there is a danger of falling.
When welding on roof parapets (parapet, eaves), the hot air welder on the carrying handle (5) must be secured to a stop fixture with horizontal guides (such as rail or rope safety systems) as protection against falling.
With respect to the safety chain, care must be taken to ensure that all of the safety elements (carabiner hooks, ropes) have a minimum load-carrying capacity of 7 kN in every direction that can be anticipated.
For the suspension of the machine, it is mandatory to use clasp carabiners (Twist-Lock or screw types). All safety chain connections must be installed and checked in accordance with manufacturer specifications.

Before each use and after unusual occurrences, the carrying handle (5) that is used for fastening the safety rope must be inspected by an individual with expertise in this area.  The carrying handle (5) is not permitted to exhibit any cracks, corrosion, notches or other material faults.
The additional weights must be reliably secured with the safety clamps (1 each at the front and rear) provided for this purpose.

Caution
Only secure the hot air welding machine by the carrying handle (5).
Caution
The hot wedge welding machine must never be fastened to single anchoring points which allow ropes to sag. The connection equipment must always be set to the shortest length possible in order to eliminate any chance of falling over the edge of the parapet.

Caution
The effects of gravity mean a danger of uncontrolled falling or sinking. The securing point is not designed to withstand the shock-like stress of an abrupt fall.
Absolutely contact the manufacturer if anything is unclear during installation or operation.

In cases of supply power failure, during work interruptions, or when cooling down, you must swivel the hot-air blowers (10) into the park position and allow them to engage there.
Take care to ensure that the hot-air blower lock (15) engages.

Power cord and extension cable

• The nominal voltage specified on the device (see technical data [2]) must match the supply voltage.
• The power cord (1) must be able to move freely and must not hinder the user or third parties during work (trip hazard).
• The extension cables must be authorized for the utilization site (such as, outdoors) and be marked accordingly.
  Take the necessary minimum cross-section for extension cables into account as required.
  On-site generators for power supply
  When using on-site generators as a power supply, please ensure that the on- site generators are grounded and equipped with residual-current circuit breakers.
  For the nominal output of the power plants, the formula “2 x nominal output of the hot-air welder” applies.

6.2 Operating readiness
Hook up the strain relief of the power supply cord (1) into the spiral holder (25) and then check the basic setting of the welding nozzle (9).

6.3 Positioning the device

• Check whether the material to be welded is clean between the overlap on both the upper and lower sides.
• Then check whether the welding nozzle (9), drive/pressure roller (8), deflection roller (27), and press-down belt (26) are clean.
• Swivel the hot-air blower (10) so it engages in the park position.
• Now raise up the hot air welder by the guide bar (22, 24) and move the device to the desired welding position.
• Now position the welding plate (see the scope of delivery[4.2]) and then swivel the track guide roller (16) downwards.
• Take care to ensure that the track guide roller (16) is positioned parallel to the drive/pressure roller (8).

Caution
The effects of gravity mean a danger of uncontrolled falling or sinking. The securing point is not designed to withstand the shock-like the stress of an abrupt fall.
Absolutely contact the manufacturer if anything is unclear during installation or operation.

FAQ, causes and actions UNIROOF 700

– The machine switches on automatically after the blowers have been switched on:

• If the air temperature is higher than 100°C when the device is switched on – which can occur, for example, if the device is disconnected from the power supply without cooling down – the device automatically switches to cooldown mode. The cool-down process is finished when the air temperature is less than 100°C for 2 minutes.

– The machine switches off automatically:

• In Standby operation, the heating is switched off automatically after the time elapses that the user has stored (see also Standby mode [10.5]).

Welding result of deficient quality:

• Check drive speed, welding temperature and air volume.
• Clean the welding nozzle (9) with a wire brush (see Maintenance [7.4])
• Welding nozzle (9) set incorrectly (see Setting the welding nozzles [5.1]).

If the set welding temperature still has not been reached after 5 minutes:

• Check the supply voltage
• Reduce the air volume

The device does not move forward in a straight line:

• Align the track guide roller (16) so that it is parallel and linear to the drive/pressure roller (8) (see welding sequence [7.2]).
• Adjust the transport roller (13) to the movable transport axle (14) (see Adjust the movable transportation axle [patent EP3 028 836 pending] [5.4])

Operation of your UNIROOF 300

13.1 Starting the device

• Once you have prepared the working area and the hot air welder in accordance with the description, connect the hot air welder to the supply voltage.
• Use the main switch (19) to switch the hot-air welder on.
  After connection, the start screen appears briefly on the display of the operating unit (2) with the version number of the current software release and the device designation.

If the device was allowed to cool down beforehand, this will be followed by a static
display of the setpoints for the most recent set welding parameters.
At this stage, the heating, blower, and drive are switched off.
Now switch the heating on with the Heating On/Off button.

13.2 Welding sequence
Preparing for welding
As soon as you have switched on the heating, you will see a dynamic display of the current air temperature (setpoint and actual value). All welding parameters (welding speed,  temperature and air volume) can be set.

• Make sure that the welding temperature has been reached before commencing work (LED stops flashing). The heat-up time is 3–5 minutes.
• Now carry out test welds in accordance with the welding instructions of the material manufacturer and/or national standards or regulations and inspect the results. Adjust the welding profile as required.

Start welding

• Pull the hot-air blower lock lever (15), lower the hot-air blower (10), and guide the welding nozzle (9) between the overlapping sheets up to the stop.

• The drive motor starts automatically as soon as the hot-air blower (10) is engaged.
  Guiding the device during the welding process

• Guide the hot-air welder by the guide bar (22, 24) or by the carrying handle (5) along the overlap, and also observe the position of the track guide roller (16) at all times.

• Avoid applying pressure to the guide bar (22, 24) during the welding process, as doing so could lead to welding faults.

13.3 Finishing welding

• After finishing welding, pull the hot-air blowers lock (15), extend the hot-air blowers (10) up to the stop, and swivel them upwards until they engage.
• Then swivel the track guide roller (16) upwards.

13.4 Switching off the device/Maintenance

• Use the heating (31) button to switch off the heating so that the welding nozzle (9) cools down.
  The blower switches off automatically after approx. 6 minutes.
  Wait until the device has cooled down.
  Now switch off the device with the main switch (19) and disconnect the power cord (1) from the electrical network.
  Check the power cord (1) and plug for electrical and/or mechanical damage.
  Use a wire brush to clean the welding nozzle (9).
