Please also consider the outside parameters like how clean the air is, if there is higher voltage, damp or wet conditions. Those will affect the lifetime of the carbon brushes and make it significantly smaller. Under the best conditions for the RiOn it’s approx. 1500 working hours and ErOn is approx. 1200 working hours. Once the brushes are changed, the lifetime is cut in half, if they are changed another time it’s cut in half again.

On the back of the machine is green a power button. Press it “on” and cool air will begin circulating through the heat gun.
To the left of the power button is round knob. It is the air flow knob.
Above the air flow knob is the speed knob.
For your heat, go to the heat gun. You will turn the red potentiometer knob for your heat selection just as you do with your hand-held units. Set your desired temperature (you will notice that there is still cool air blowing out of the nozzle), you must push the toggle switch on the heat gun in order to activate the heating element. Once you feel hot air blowing out of the nozzle, you should be ready to weld in approx. 3-5 minutes.
You will align your welder just like our larger Laron welder: the pressure wheel on the front of the machine below the black weight, is on the top edge of overlap layer and the guide wheel (aka: pizza wheel) is on the lower edge of the overlap layer.
The outside of your pressure wheel and the guide wheel must be aligned for your machine to move in a straight line. (See operations manual).
You will want to see a slight angle of the nozzle from the outside angling down to the inside of the weld (not flat). (See operations manual)
You want to see 1.5mm of the edge of the nozzle sticking out of the edge of the top layer of single ply material.
The distance of the nozzle from the pressure wheel should measure 32mm-42mm (approx. 1.25” – 1.65”) from the hub nut (center) of the pressure wheel.
At lunch time or at the end of the day, turn the toggle switch on the heat gun off, letting cool air circulate through the machine for approx. 3-5 minutes. Once you feel consistent cool air blowing out of the nozzle, press the green button to “off”.
Always cool down the machine using this process. It will save your heating elements and promote a safe work environment.
Always store your Roofon with the nozzle in the welding (down) position, inserted in front of the pressure wheel to save wear and tear on the heat gun.
Check the power cord and the plug to make sure they’re wired correctly (Reference: Wiring Diagram)
If it’s wired correctly, there’s could be a broken wire from the plug clamping down onto the cord. The best way to check is to remove the plug, take a pair of pliers, and pull each wire. If one of them pulls out, then you must cut back approximately 6 inches, and rewire your plug.
If there’s no broken wire, there could be a broken wire on the other end of the cable where it connects to the housing. To fix that, you have to remove 4 screws that hold the cover on, disconnect the wire inside, pull the wire out, cut 6 inches back, and redo the wire inside the housing
Use 10mm wrench to loosen the two 10mm bolts of the mounting bracket so you can move the tool around to achieve the 2mm opening. Check the proper distance between the nozzle tip and the center of pressure roller. Use a ruler to make sure you have the nozzle 38mm-42mm or 1 ½ - 1 5/8” from the center of the pressure roller bolt. Check again to make sure still have 2mm or 1/8” nozzle opening sticking out pass the silicone wheel, then tighten the two 10mm bolts.
FOR ROOFON EDGE: Guide roller might be out of adjustment.
The distance between rocker arm and the edge of guide roller should be 10mm. Take 17mm wrench, loosen nut on the back side, turn the axle until you have achieved 10mm distance. Then tighten up the nut.
FOR ROOFON: Guide roller might be out of adjustment.
