- Page 16 ƒ Anti-fall protection when working in areas where there is a fall hazard ƒ When welding on roof parapets (parapet, eaves), the hot air welder on the carrying handle (4) must be secured to a stop fixture with horizontal guides (such as rail or rope safety systems) as protection against falling. ƒ 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. It is mandatory to use locking carabiners (twist-lock or screw types) to hook the unit. You must properly install and check all connections of the safety chain according to the manufacturer’s specifications. Before each use and after unusual occurrences, the carry- ing handle (4) that is used for fastening the safety rope must be inspected by an individual with expertise in this area. The carrying handle (4) is not permitted to exhibit any cracks, corrosion, notches or other material faults. Secure the additional weights with the additional plates provided (1 per weight). Additional plate...
- Page 17 Caution ƒ Only secure the hot air welding machine by the carrying handle (4). ƒ Never fasten the hot wedge welding machine to single anchoring points which allow ropes to sag. Always set the connection equipment to the shortest length possible in order to eliminate any chance of falling over the edge of the parapet. Caution ƒ The device may fall or drop in an uncontrolled manner due to gravity. The securing point is not designed to withstand the shock-like stress of an abrupt fall. ƒ Please do not hesitate to contact the manufacturer if anything is unclear during installation or operation. Power cord and extension cable ƒ The nominal voltage specified on the device (see Technical data [2]) must match the supply voltage. ƒ The power cord (6) must be able to move freely and must not hinder the user or third parties during work (trip hazard). ƒ The extension cables must be authorized for the utilization site (e.g., outdoors) and be marked accord- ingly. 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 “1.5–2 × nominal output of the hot-air welder” applies.

Page 47: Settings And Functions Of The Varimat 300 Software
16. Settings and functions of the VARIMAT 300 software 16.1 Setting the parameter units The units for the welding speed and for the temperature can be adjusted by you. Temperature: °C °F Speed: ƒ Hold down the Drive On/Off (30) and Heating On/Off (31) buttons and connect the power cord to the power supply. “UNIT” then appears on the display. ƒ Press the Confirm (33) button to confirm and use the Plus/Minus (32) buttons to set the desired units. ƒ Press the Confirm (33) button to confirm and use the Plus/Minus (32) buttons to select SAVE. Press the Confirm (33) button to confirm; the units are then saved. The device then restarts automatically. 16.2 Setting the welding parameters You can regulate the set values of the three welding parameters individually, even during operation. During operation, the selected range automatically switches to the row welding speed (35) after 5 seconds. Proceed as follows: Select: Select the desired set value for drive, temperature or air with the Confirm (33) button. Representation: The selected area is indicated by a bar at the side Setting: Use the Minus/Plus buttons (32) to adjust the selected set value to match your require- ments. -
Page 48: Cool-Down Mode
16.3 Cool-down mode The heating is switched off during the cool down process. The set values cannot be changed during the cool down process. If the air temperature is more than 60 °C when the device is switched on, the device switches automatically to Cool down mode. The cool-down process is finished when the air temperature is less than 100 °C for 2 minutes. If you want to switch the heating on again, you must press the Heating “On/Off” button (31). 16.4 Monitoring welding parameters during runtime Welding speed, air temperature and air volume are monitored continuously. If an actual value deviates from the set value according to the individual settings, this is indicated in the working display (see Display symbols of welding temperature [15.5]). -

18. Frequently asked questions, causes and actions VARIMAT 300 The device switches on automatically after the blowers have been switched on: ƒ 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 the cooling process – the device automatically switches to cool-down mode. The cool-down process is finished when the air temperature is less than 100 °C for 2 minutes. Welding result of deficient quality: ƒ Check drive speed, welding temperature and air volume. ƒ Clean the welding nozzle (11) with a wire brush (see maintenance [7.4]) ƒ Welding nozzle (11) set incorrectly (see Setting the welding nozzles [5.1]) ƒ Track guide roller (16) incorrectly adjusted and causing undulation Incorrect device operation, contact salessupport@leister.com ƒ After 5 minutes at the most, the set welding temperature has still not been reached: ƒ Check the supply voltage ƒ Reduce the air volume ƒ Check heating element Device does not move forward in a straight line: ƒ Align the track guide roller (16) so that it is parallel and linear to the drive/pressure roller (10) (see welding sequence [7.2]). ƒ Use the setting gauge for easy setting (included in the scope of delivery) ƒ Set the transport roller (14) with the track setting (15), check the track setting display (13). 26 10 Continue to next page... -
