Bring the automatic welding machine into the welding position.
Push the transport roller to the right in welding position, take care that the spring sheet
engages.
Push the guide roller downward and fix it with the hexagon nut on the threaded bar.
Outside edge of the overlap, outside edge of pressure roll and outside edge of guide roller
must form a line. Please refer to the sketch below:
START UP OF THE WELDING MACHINE
If it is not possible to start the motor, a reset is needed.
oReset: Turn off main switch –wait for 3 seconds –Turn on main switch
Before connecting the tool to the mains supply please check that:
-Main switch is on pos. 0 OFF.
-Drive switch is on pos. 0.
-Heating switch is on pos. 0.
-Potentiometer of the air flow is on pos. 0 (100%).
-The hot air blower is on pos. stand by (lifted up).
-Put the plug into the socket.
-Put the main switch on pos. 01.
The tool now heats up to the last selected set temperature.
