The owner/operator undertakes to ensure that the only - The VR 4040 unreeling device is designed for indoor use only. It is not persons allowed to work with the VR 4040 unreeling permitted to set it up or operate it outdoors.
- Welding must NEVER be performed on containers that have had - For this reason, only operate the VR 4040 unreeling device when the gases, fuels, mineral oils etc. stored in them. Even small traces of cover is closed, the swing-out ramp is folded back up into place, the these substances left in the containers are a major explosion hazard.
The optional end-of-wire watchdog alerts the operator in good time to the fact that the wire spool will soon need changing. This makes it possible The VR 4040 unreeling device is a further member of the modular family to prevent unnecessary disruption of the production process. If the of Fronius wire-feeding equipment.

INSERTING THE WELDING WIRE N.B.! When unwinding the wire from the spool, lift the “lever + drawback Warning! Welding wire that suddenly breaks away and lashes pulley” unit. This releases the wirespool brake, making the wire easy to out can cause very serious injury to the face and eyes. unreel.
230 V INTERIOR HEATING SYSTEM, UNREGULATED General remarks In this way, no “sweating” (the phenomenon by which atmospheric water from warm ambient air condenses on a cold surface) can take place. The interior heating system is designed to operate with a constant heat output.
Operating Instructions of the unreeling device! heating system. The safety isolating transformer is located in a separate housing, outside the VR 4040. The pre-set temperature of the interior N.B.! Mount the housing for the safety isolating transformer on the side compartment is kept constant by a digital temperature controller.

(Fig.12). Limiting the tensile load on the wire The VR 4040 unreeling device offers the facility to limit the increased ACCELERATING tensile load on the wire during acceleration by means of an overload coupling (Fig.11).
EQUILIBRIUM, AND WORKING POSITION In equilibrium, the wire being fed by the wirefeeder and the wire at the periphery of the wire spool both have the same speed. After briefly swinging back and forward before reaching the working position, the “lever + drawback pulley” unit no longer moves, and stays in the working position (Fig.12).
By “response”, we mean the speed at which the braking force is built up. - Particular danger spots N.B.! The VR 4040 unreeling device comes with default settings that are ideal for a very wide range of wire spools and welding wires.
upward (Fig.13) N.B.! Make sure that the “lever + drawback pulley” unit is resting - Push the clamping ring against the bottom mechanical limit-stop (Fig.12). N.B.! The further up the clamping ring sits, the sooner the full braking - To do this, turn the wire spool in the direction of unreeling effect starts to occur.
- Fit the damper back in - Close the VR 4040 SETTING THE WIRE TENSILE-FORCE LIMITATION The VR 4040 unreeling device offers the facility to limit the increased tensile load on the wire during acceleration by means of an overload coupling .
TROUBLESHOOTING GUIDE Fault Cause Remedy - Wire jumps out of the guide grooves of Braking force has been set too low Set a higher braking force (See “Adjusting the the drawback pulleys braking force”) - Wire is not sufficiently tensioned when Spring not suspended from braking lever Suspend spring from braking lever the unreeling device is idling...
