OPERATION

General safety regulations for handling the equipment can be found in the "SAFETY" chapter
of this manual. Read it through before you start using the equipment!

WARNING!

To avoid shock, do not touch the electrode wire or parts in contact with it, or uninsulated cable
or connections.

NOTE!

When moving the equipment, use the handle intended for transportation. Never pull the
equipment by the welding torch.

WARNING!

Make sure the side panels are closed during operation.

WARNING!

To prevent the reel from sliding off the brake hub, lock the reel in place by tightening the brake
hub nut.

NOTE!

Replace the brake hub nut and the brake hub sleeve if they are worn out and don't lock
properly.

CAUTION!

Before threading welding wire, make sure the chisel point and burrs have been removed from
the end of the wire to prevent the wire from jamming in the torch liner.
