Adjusting Press Force of Wire Drive Reel
Setting Braking Torque of Welding Wire Reel Connecting Shaft
Type and Selection of Wire Drive Reels
Changing Wire Drive Reels
To change the reels:
Properly set the press force of reels. If the press force is too low, wire slips on reels if
the press force is too high, reels crushes the wire or wire jams in. Press force
increases when driver reel press force setting turned clockwise, when turned counter
clockwise press force decreases.
To prevent welding wire to discharge from the reel, fastener that holds the reel is
equipped with a braking system.
Braking setting is performed with a spring located in the fastener.
When springs tightened to the left, braking torque increases, when tightened to the
right, braking torque decreases.
Wire drive unit is equipped with V channeled reels set for Ø 0.8, 1.0 and 1.2 mm solid
welding wire. For Ø 1.2 ve 1.6 mm flux-cored there are "Notched-V" channeled reels.
Make sure that the diameter of installed reel is suitable for the diameter of welding wire
being used.
There is a mark on the side surface of reels indicating the profile of wire drive groove
suitable for the wire diameter to be used. This mark is not seen after the installation.
For steel and stainless steel welding wires V type reels should be used.
For aluminium wires U type reels should be used.
For flux cored Notched-V type reels should be used.
Release the press force setting of feeder reels.
Remove the reel desired to be changed.
Install the new reel making sure that it fits into its place.
Again fix the press force setting.
