welding
2.The operator must ensure that:
no unauthorized person is stationed within the working area of the equipment when it is started up.
no-one is unprotected when the arc is struck
3.The workplace must:
be suitable for the purpose
be free from drafts
4.Personal safety equipment
Always wear recommended personal safety equipment, such as safety glasses, flame-proof clothing, safety gloves.
Do not wear loose-fitting items, such as scarves, bracelets, rings, etc., which could become trapped or cause burns.
5.General precautions
Make sure the return cable is connected securely.
Work on high voltage equipment may only be carried out by a qualified electrician.
Appropriate fire extinquishing equipment must be clearly marked and close at hand.
CAUTION
Class A equipment is not intended for use in residential locations where
the electrical power is provided by the public low-voltage supply system.
There may be potential difficulties in ensuring electromagnetic
compatibility of class A equipment in those locations, due to conducted
as well as radiated disturbances.
Arc welding and cutting can be injurious to yourself and others. Take precautions when welding and
cutting. Ask for your employer's safety practices which should be based on manufacturers' hazard
data.
ELECTRIC SHOCK - Can kill
Install and earth the unit in accordance with applicable standards.
Do not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing.
Insulate yourself from earth and the workpiece.
Ensure your working stance is safe.
FUMES AND GASES - Can be dangerous to health
Keep your head out of the fumes.
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.
Protect your eyes and body. Use the correct welding screen and filter lens and wear protective
clothing.
Protect bystanders with suitable screens or curtains.
FIRE HAZARD
Sparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby.
NOISE - Excessive noise can damage hearing
Protect your ears. Use earmuffs or other hearing protection.
Warn bystanders of the risk.
MALFUNCTION - Call for expert assistance in the event of malfunction.
Read and understand the instruction manual before installing or operating.
PROTECT YOURSELF AND OTHERS!
ESAB can provide you with all necessary welding protection and accessories.
WARNING
Do not use the power source for thawing frozen pipes.
CAUTION
Read and understand the instruction manual before
installing or operating.

Duty cycle
The duty cycle refers to the time as a percentage of a ten-minute period that you can weld or cut at
a certain load without overloading. The duty cycle is valid for 40° C.
Enclosure class
The IP code indicates the enclosure class, i. e. the degree of protection against penetration by solid
objects or water. Equipment marked IP23 is designed for indoor and outdoor use.
Application class
The symbol indicates that the power source is designed for use in areas with increased
electrical hazard.
4INSTALLATION
The installation must be carried out by a professional.
CAUTION
This product is intended for industrial use. In a domestic environment this product may
cause radio interference. It is the user's responsibility to take adequate precautions.
Place the power source so that its cooling air inlets and outlets are not obstructed.
4.2Mains power supply
Check that the welding power source is connected
to the correct voltage and that the correct fuse
size is used.

5.3Connection 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.
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.
5.5MMA 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
cmha2p11
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.

5.6TIG 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.
