3 INTRODUCTION
The MEK 2 is an encapsulated wire feed unit with two roller feed.
The unit provides space for a 300 mm diameter wire reel and has a built--in posi-
tioner.
For a wire feed unit to be complete it must be equipped either with a turnable,
counterbalance device or a carriage. A turnable or counterbalance device a llow the
wire feed unit to be mounted on a pivot on the power source. A carriage allows the
wire feed unit to be moved easily over the floor or work table.
A wire feed unit and turnable or carriage can also be fitted with a support device and
suspended over the work place.
Details of ESAB’s accessories for the wire feed units can be found on page
84.

Setting the wire feed pressure
Start by making sure that the wire moves smoothly through the wire guide. Then
set the pressure of the wire feeder’s pressure rollers. It is important that the
pressure is not too great.
Fig 1 Fig 2
To check that the feed pressure is set correctly, you can feed out the wire against
an insolated object, e.g. a piece of wood.
When you hold the pistol approx. 5 mm from the piece of wood (fig. 1) the feed
rollers should slip.
If you hold the pistol approx. 50 mm from the piece of wood, the wire should be
fed out and bend (fig. 2).
There is a risk of tipping if the wire feed cabinet is fitted with a counterbalance arm. Secure the
equipment, especially if used on an uneven or sloping surface.
Limit the angle of rotation of the wire feed cabinet using the straps supplied.
When moving the equipment, do NOT pull on the torch.
WARNING!
7 MAINTENANCE
Note:
All warranty undertakings given b y the supplier cease to apply if the customer
attempts to rectify any faults on the machine during the warranty period.
Regularly maintenance is important for reliable and safe operations.
S Cleaning and replacement of the wire feed mechanism’s wear parts should take
place periodically to ensure trouble free wire feed.
S Note that an excessive pressure setting can result in abnormal wear on the pres-
sure roller, feed roller and wire liner.

The brake hub
The hub is adjusted when delivered, if
readjustment is required, follow the instructions

slack when wire feed stops.
S Adjusting the braking torque:
S Turn the r ed handle to the locked position.
S Insert a screwdriver into the springs in the hub.
Tu rn the springs clockwise to reduce the braking torque
Turn the springs anticlockwise to increase the braking torque. NB: Turn both
springs through the same amount.
