WARNING
READ AND UNDERSTAND THE INSTRUCTION MANUAL BEFORE INSTALLING OR OPERATING.
ARC WELDING AND CUTTING CAN BE INJURIOUS TO YOURSELF AND OTHERS. TAKE PRECAU-
TIONS WHEN WELDING. ASK FOR YOUR EMPLOYER’S SAFETY PRACTICES WHICH SHOULD BE
BASED ON MANUFACTURERS’ HAZARD DATA.
ELECTRIC SHOCK -- Can kill
S Install and earth the welding unit in accordance with applicable standards.
S Do not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing.
S Insulate yourself from earth and the workpiece.
S Ensure your working stance is safe.
FUMES AND GASES -- Can be dangerous to health
S Keep your head out of the fumes.
S Use ventilation, extraction at the arc, or both, to take fumes and gases away from your breathing zone
and the general area.
ARC RAYS -- Can injure eyes and burn skin.
S Protect your eyes and body. Use the correct welding screen and filter lens and wear protective
clothing.
S Protect bystanders with suitable screens or curtains.
FIRE HAZARD
S Sparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby.
NOISE -- Excessive noise can damage hearing
S Protect your ears. Use earmuffs or other hearing protection.
S Warn bystanders of the risk.
MALFUNCTION -- Call for expert assistance in the event of malfunction.

3 INTRODUCTION
MEK 4SP (Synergic Pulse) is an enclosed wire feed unit with four drive rollers. Inside
the wire feed unit there is space for a 300 mm diameter wire reel. The unit also has a
built--in swivel mounting so that the wire feed unit can be conveniently mounted on
top of the welding power source.
MEK 4SP has a number of features that the welder will find very useful, including the
ability to save the settings for 3 different welding jobs and recall these settin gs when
they are needed. You can read about this and much more on this and the following
pages.
Details of ESAB’s accessories for the wire feed units can be found on page
30.
3.1 Explanation of synergic lines
Each combination of wire type, wire diameter and gas mixture requires its own
unique relationship between the wire feed speed and voltage (arc length) in order to
maintain a stable and effective arc. MEK 4SP has 14 different combinations of
pre--programmed “ syn ergic lines“.
Once you have chosen the pre--programmed synergic line that matches your wire
type, wire diameter and gas mixture all you need to do is set the appropriate wire
feed speed for your welding task. T he voltage (arc length) is automatically adjusted
in accordance with the pre--programmed synergic line you have chosen, i.e. you
have one--knob control.
Because different welding tasks and joint preparations require slightly different
voltages (arc lengths) the voltage can naturally be fine--tuned either side of the
pre--programmed value. When this is done the green light on the front panel goes
out. This indicates that the voltage is above or below the pre--programmed value.
If you want to return to the original setting you simply adjust the voltage until the
green light comes on again.

6 OPERATION
General safety regulations for the handling of the equipment can be found on
page 13. Read through before you start using the equipment!
WARNING!
Rotating parts can cause injury, take great care.
To prevent the reel sliding off the hub: Lock the reel in place by turning
the red knob as shown on the warning label attached next to the hub.
WARNING!
Setting the wire feed pressure
Start by making sure that the wire m oves smoothly through the wire guide. T hen
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!

6.1 Startingtoweld
By moving the plug (17) to the upper or lower position you can switch between two
different start modes.
Normal start
with the plug (17) in the lower position the wire feed speed at the start of welding is
the same as the preset wire feed speed during welding.
Inch start
with the plug (17) in the upper position the wire feed speed at the start of welding is
reduced (1.9m/min) and then rises to the preset wire feed speed when the arc is
established.
6.2 Pulse welding on
6.2.1 Synergic mode
Set the toggle switch on the circuit board (25) to position A and set the selector
switch on the front panel (22) to the synergic line that matches the wire type, wire
diameter and gas you intend to use. T here a re 8 synergic lines to choose from , (see
table page 17).
When the “ Pre--set“ button (23) is pushed in, the wire feed speed and voltage are
shown on the display.
Select the wire feed speed you want to use for welding, the voltage will automatically
follow the pre--programmed synergic line.
The green lamp (24) above
the voltage control will light up when
the voltage falls on the synergic line.
You can use the voltage control knob (8) to
adjust the voltage around the working point.
The actual voltage and current are shown on
the display during welding.
There are a further two synergic lines in position B.
The synergic lines have different ranges of settings
for wire feed speed (see table page 17).

6.4 Manual mode
Adjusting vo ltag e an d wire feed speed.
Set the selector switch on the front panel
(22) to manual Hold in the “pre--set“ button
(23) while you set the desired voltage and wire feed
speed on the display. T he actual voltage and current
are shown on the display during welding. NOTE! Pulse
welding is not possible in manual mode.
6.5 Saving the working setting
Set the program selector switch (19) to one of
the three settings 1,2 or 3. Hold in the “pre--set“
button (23) while you set the desired voltage and
wire feed speed on the display. To save the
welding parameters you have selected, press the
save button (20) until the green lamp (21) lights
up. You can save three different working settings
using the program selector switch.
6.6 Program mode
To use one of the 3 stored working settings, switch the function selector switch (22)
on the front panel to mode “P“ and the program selector switch (19) to mode 1,2 or 3
to recall the chosen data and begin welding.
These weld data settings can also be recalled using the program selector switch on
the welding torch.
It is not possible to adjust the voltage or the wire feed speed around the chosen
working setting.
7 MAINTENANCE
Note:
All warranty undertakings given by the supplier cease to apply if the customer
attempts to rectify any faults on the machine during the warranty period.
Regular maintenance is important for safe and reliable operation.
S Regularly blow the wire liner clean and clean the gas nozzle.
S The wear components of the wire feed mechanism should be replaced at regular
intervals in order to ensure reliable wire feeding.
Note that using excessive pressure on the wire feed rollers can cause excessive
wear to the pressure roller, feed roller and wire liner.

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