OPERATION
7. MIG WELDING 8. WELDING PROPERTIES
There are a range of welding movements used in MIG welding. Generally some
form of zig-zag motion is used to ensure the arc acts against both sheets to be
welded. Below are some details that may help with the welding process.
Travel Speed
The torch should be moved along at a smooth speed that will give the size of run
required. At the same time, the wire is fed downwards to keep the correct welding
distance at all times. Excessive travel speeds lead to poor fusion and lack of
penetration. While too slow a rate of travel may damage the workpiece and can
lead to burning a hole through the material.
Electricity
The electricity ows through the wire and will not leave the wire unless it is near
an earthed object.
Electricity always nds the fastest path to the earth. When the earth cable clamp
is connected to the metal work piece a direct earth connection is created back to
the welder. When the wire touches or is near the earthed work piece when the
trigger is squeezed, electricity ows through the wire, the metal work piece and
then through the earth cable straight back to the welder.
Earth Clamp
Prior to connecting the earth clamp it may be necessary to clean the surface of
the work piece using the metal brush. Attach the earth clamp rmly to the work
piece ensuring there is good metal to metal contact. Clamp it where it will not be
in the way. This clamp provides an earth connection back to the welder.
Welding Wire
There are many variables that you will need to take into account when choosing
your welding wire size and type. Below are some of the things you need to take
into account when choosing the welding wire:
• Thickness of the material to be welded
• Position and type of welding joint
• Maximum welding capacity of your welder
• How much penetration will be required for strength
• Type of bead desired for the weld
• Whether you are using a shielding gas or not
• Type of material to be welded
The above chart is only intended to show general guidelines for different wire
sizes and for different thicknesses of material. The settings should only be used
at the beginning of a weld and must be adjusted after stopping and carefully
inspecting the weld. Proper welding takes good technique and practice.
2 Attach the earth clamp
to the workpiece so that
there is a good electrical
connection.
4 Position the tip roughly
8mm from the workpiece
at an angle or 200from
vertical in the direction of
movement.
Note: Cutting the wire about
10mm long and holding the
torch so the wire touches the
workpiece is a good way to
obtain this distance.
1 Ensure that your work
piece is securely
mounted and is
cleaned and prepared
ready for welding.
3 Switch the MIG
welder on and
position the welding
mask in front of your
eyes.
5 Squeeze the MIG
torch trigger to start
the weld and once
completed release the
trigger.
Before welding ensure that:
• You have read and understand the safety section of this
manual.
• There is sufcient ventilation, particularly at the front and
rear of the unit.
• You have an adequate re-ghting devices on hand.
• You wear adequate protective gear while operating the MIG
welder.

WELD SETTINGS CHART

• Under no circumstances should the housing of the welder be opened.
• Always protect your eyes and face with a welding mask.
• Wear appropriate protective clothing such as a welding apron and sleeved gloves
etc.
• Avoid exposing skin as UV rays are produced by the arc.
• Screen off the work place to protect others working nearby from UV rays.
• Welding materials with contaminated surfaces may generate toxic fumes. Ensure
the surface is clean before welding. Avoid operating on materials cleaned with
chlorinated solvents or near such solvents.
• Do not weld metal equipment that holds/contains ammable materials, gases or
liquid combustibles.
• Zinc-plated or galvanized material should not be welded as the fumes created are
highly toxic.
• Do not use the welder in damp or wet conditions.
• Do not use cables with worn insulation or loose connections.
• Disconnect from the power supply before replacing electrodes.
• Avoid direct contact with the welding circuit.
• Do not use the welder to defrost piping.
• Ensure the welder is placed on a level surface to prevent overturning.
• Provide adequate ventilation or a means for removal of the welding fumes
produced (forced circulation using a blower or fan).
Fumes
Toxic gases are given off during the ARC welding process, which may collect in the
welding area if the ventilation is poor. Be alert at all times to the possibility of fume
build-up. In small or conned areas use a fume extractor.
Glare
The electric arc generated by the arc process gives direct heat and ultraviolet
radiation. It is essential that the eyes of the operator and bystanders are protected
from the glare during welding.
ALWAYS USE A FACESHIELD OR WELDING HELMET FITTED WITH THE
CORRECT GLASS FILTER.
Heat
It is desirable that welding gloves are worn whilst welding. They will protect the
hands from ultra-violet radiation and direct heat of the arc.
Dress
In addition to face shield, welding gloves and overalls, other types of protective
clothing should be worn when welding. Additional protective clothing such as a
leather apron, sock protectors and a hat will all assist in reducing any injuries due to
heat, sparks and slag produced during welding.
OVERALLS should also be worn. They should be of type designed to be buttoned at
the wrists and the neck.

TROUBLESHOOTING
Thermal Overload
All Welders have a feature called a duty cycle.
Duty cycle on a welder refers to the time in which the welder operates
during normal welding.
A welder can only weld for a certain continuous period of time before
it requires to cool down.
If the internal components of the welder should become hot the
welder could overheat. If the welder overheats the Thermal Overload
Protection feature will automatically shut down the welder.
THIS CAN OCCUR IN HEAVY USE AND DOES NOT INDICATE A
FAULT.
The Welder will cease to weld and the Thermal Overload LED light
will turn on. This LED indication light is just to inform you that your
welder is becoming too hot and requires to cool down to protect the
internal components of the welder. Do Not turn your welder Off as the
welder has an internal cooling fan and this will assist your welder to
cool down quicker. Reducing the cooling time will enable you to get
back to your welding job quicker.
Depending on how many Amps or how heavy the welding you are
doing the cooling time may take up to 10 Minutes for your welder to
cool down so you can return to your welding job.
Disconnect the welding power source from the mains supply voltage
before disassembling. Welding equipment should be regularly checked
by a qualied electrical trades person to ensure that:
• The main earth wire of the electrical installation is intact.
• The power point for the welding power source is effectively earthed
and of adequate current rating.
• Plugs and cord extension sockets are correctly wired.
• Flexible cord is of the 3-core tough rubber or plastic sheathed type of
adequate rating, correctly connected and in good condition.
• Welding terminals are shrouded to prevent inadvertent contact or
short circuit.
• The frame of the welding power source is effectively earthed.
• Welding leads and electrode holder are in good condition.
• The welding power source is clean internally, especially from metal
ling, slag, and loose material. If any parts are damaged for any
reason, replacement is recommended.
• Prior to operation, use the terminal spanner to securely tighten the
terminal knobs.
Cleaning the Drive Rolls
Clean the grooves in the drive rolls frequently. This can be done by
using a small wire brush. Also wipe off, or clean the grooves on the
upper drive roll. After cleaning, tighten the drive roll retaining screws.
Note: Ozito Industries will not be responsible for any damage or
injuries caused by the repair of the tool by an unauthorised person or
by mishandling of the tool.
