5.3 Connection of welding and return cable
The power source has two outputs, a positive terminal and a negative terminal, for
connecting welding and return cables. The output to which the welding cable is
connected depends on the type of electrode used. The connecting polarity is stated
on the electrode packaging. Connect the welding cable to the terminal stated on the
electrode packaging.
Connect the return cable to the other output on the power source. Secure the return
cable's contact clamp to the work piece and ensure that there is good contact
between the work piece and the output for the return cable on the power source.

5.4 Overheating protection
The welding power source has a thermal overload trip which operates if the
temperature becomes too high, interrupting the welding current and lighting a yellow
indicating lamp on the front of the power source. The thermal overload trip resets
automatically when the temperature has fallen.
5.5 MMA welding
Arc 152i gives direct current, and you can weld most metals to alloy and non-alloy
steel, stainless steel and cast iron. Arc 152i allows you to weld most coated electrodes
from ∅1.6 to ∅3.25.
MMA welding may also be referred to as welding with coated electrodes. Striking the
arc melts the electrode, and its coating forms protective slag.
If, when striking the arc, the tip of the electrode is pressed against the metal, it immedi
ately melts and sticks to the metal, rendering continued welding impossible.
Therefore, the arc has to be struck in the same way that you would light a match.
Quickly strike the electrode against the metal, then raise it so
as to give an appropriate arc length (approx. 2 mm). If the arc
is too long, it will crackle and spit before finally going out com
pletely.
If you are working on a welding bench, check before attempting
to strike the arc that residual waste metal, pieces of electrode
or other objects on the bench do not insulate the part to be
welded.
Once the arc has been struck, move the electrode from left to
right. The electrode must be at an angle of 60°to the metal in
relation to the direction of welding.
When you want to weld wide beads, or when you want the weld
to be so thick that you have to weld in a number of layers, how
ever, you have to use lateral movements.
5.6 TIG welding
TIG welding melts the metal of the workpiece, using an arc struck from a tungsten
electrode, which does not itself melt. The weld pool and the electrode are protected
by shielding gas.
TIG welding is particularly useful where high quality is demanded and for welding
thin plate. Arc 152i also has good characteristics for TIG welding.
In order to TIG weld, Arc 152i must be equipped with:
a TIG torch with gas valve
a welding gas cylinder (a suitable welding gas)
a welding gas regulator (suitable gas regulator)
tungsten electrode
suitable auxiliary material, if necessary.
TIG scrape start
To scrape start lightly scrape the tungsten
electrode against the workpiece to create an arc.

6 MAINTENANCE
Regular maintenance is important for safe, reliable operation.
CAUTION
All guarantee undertakings from the supplier cease to apply if the customer attempts any
work to rectify any faults in the product during the guarantee period.
6.1 Inspection and cleaning
Check regularly that the welding power source is not clogged with dirt.
How often and which cleaning methods apply depend on: the welding process, arc
times, placement, and the surrounding environment. It is normally sufficient to blow
down the power source with dry compressed air (reduced pressure) once a year.
Clogged or blocked air inlets and outlets otherwise result in overheating.
The welding torch's wear parts should be cleaned and replaced at regular intervals in
order to achieve trouble-free welding.
7 FAULT-TRACING
Try these recommended checks and inspections before sending for an authorised
service technician.
Type of fault Corrective action
No arc. Check that the mains power supply switch is turned on.
Check that the welding current supply and return cables are
correctly connected.
Check that the correct current value is set.
Check the mains power supply.
The welding current is
interrupted during welding.
Check to see whether the thermal cut-outs have tripped.
Check the mains power supply fuses.
The thermal cut-out trips
frequently.
Make sure that you are not exceeding the rated data for the
welding power source (i.e. that the unit is not being
overloaded).
Poor welding performance. Check that the welding current supply and return cables are
correctly connected.
Check that the correct current value is set.
Check that the correct electrodes are being used.
Check the gas flow.
