Safety Guidelines
These general safety norms cover both arc welding machines and plasma cutting machines unless
otherwise noted. The equipment must only be used for the purpose it was designed for. Using it in any
other way could result in damage or injury and in breach of the safety rules. Only suitably trained and
competent persons should use the equipment. Operators should respect the safety of other persons.
Prevention against electric shock
The equipment should be installed by a qualified person and in accordance with current standards in
operation. It is the user’s responsibility to ensure that the equipment is connected to a suitable power
supply. Consult with your utility supplier if required. If earth grounding of the work piece is required,
ground it directly with a separate cable. Do not use the equipment with the covers removed. Do not
touch live electrical parts or parts which are electrically charged. Turn off all equipment when not in use.
Cables (both primary supply and welding) should be regularly checked for damage and overheating. Do
not use worn, damaged, under sized or poorly jointed cables. Ensure that you wear the correct protective clothing, gloves, head and eye protection. Insulate yourself from work and ground using dry insulating mats or covers big enough to prevent any physical contact with the work ground. Never touch the
electrode if you are in contact with the work ground, or another electrode from a different machine.
Do not wrap cables over your body. Ensure that you take additional safety precautions when you are
welding in electrically hazardous conditions such as damp environments, wearing wet clothing, and
metal structures. Try to avoid welding in cramped or restricted positions. Ensure that the equipment is
well maintained. Repair or replace damaged or defective parts immediately. Carry out any regular maintenance in accordance with the manufacturer’s instructions.
Safety against fumes and welding gases
Locate the equipment in a well-ventilated position. Keep your head out of the fumes. Do not breathe
the fumes. Ensure the welding zone is in a well-ventilated area. If this is not possible provision should be
made for suitable fume extraction. If ventilation is poor, wear an approved respirator. Read and understand the Material Safety Data Sheets (MSDS’s) and the manufacturer’s instructions for metals, consumable, coatings, cleaners, and de-greasers. Do not weld in locations near any de-greasing, cleaning, or
spraying operations. Be aware that heat and rays of the arc can react with vapours to form highly toxic
and irritating gases. Do not weld on coated metals, unless the coating is removed from the weld area,
the area is well ventilated, and while wearing an air-supplied respirator. The coatings on many metals
can give off toxic fumes if welded.
Prevention against burns and radiation
Arc rays from the welding process produce intense, visible and invisible (ultraviolet and infrared) rays
that can burn eyes and skin. Wear an approved welding helmet fitted with a proper shade of filter lens
to protect your face and eyes when welding or watching. Wear approved safety glasses with side shields
under your helmet. Never use broken or faulty welding helmets. Always ensure there are adequate
protective screens or barriers to protect others from flash, glare and sparks from the welding area. Ensure
that there are adequate warnings that welding or cutting is taking place.
3
Wear suitable protective flame resistant clothing. The sparks and spatter from welding, hot work pieces,
and hot equipment can cause fires and burns. Welding on closed containers, such as tanks, drums, or
pipes, can cause them to explode. Accidental contact of electrode to metal objects can cause arcs,
explosion, overheating, or fire. Check and be sure the area is safe and clear of inflammable material
before carrying out any welding.
Protection against noise
Some welding and cutting operations may produce noise. Wear safety ear protection to protect your
hearing.
Protection from moving parts
When the machine is in operation, keep away from moving parts such as motors and fans. Moving
parts, such as the fan, may cut fingers and hands and snag garments. Protections and coverings may
be removed for maintenance and controls only by qualified personnel, after first disconnecting the
power supply cable. Replace the coverings and protections and close all doors when the intervention
is finished, and before starting the equipment. Take care to avoid getting fingers trapped when loading
and feeding wire during set up and operation. When feeding wire be careful to avoid pointing it at other
people or toward your body. Always ensure machine covers and protective devices are in operation.
Precautions against fire and explosion
Avoid causing fires due to sparks and hot waste or molten metal. Ensure that appropriate fire safety
devices are available near the cutting / welding area. Remove all flammable and combustible materials
from the cutting / welding zone and surrounding areas. Do not cut/weld fuel and lubricant containers,
even if empty. These must be carefully cleaned before they can be cut/welded. Always allow the cut/
welded material to cool before touching it or placing it in contact with combustible or flammable
material. Do not work in atmospheres with high concentrations of combustible fumes, flammable gases
and dust. Always check the work area half an hour after cutting to make sure that no fires have begun
Risks due to magnetic fields
The magnetic fields created by high currents may affect the operation of pacemakers or electronically
controlled medical equipment. Wearers of vital electronic equipment should consult their physician
before beginning any arc welding, cutting, gouging or spot welding operations. Do not go near welding
equipment with any sensitive electronic equipment as the magnetic fields may cause damage.
RF Declaration
Equipment that complies with directive 2004/108/EC concerning electromagnetic compatibility (EMC)
and the technical requirements of EN60974-10 is designed for use in industrial buildings and not those
for domestic use where electricity is provided via the low voltage public distribution system. Difficulties
may arise in assuring class A electromagnetic compatibility for systems installed in domestic locations
due to conducted and radiated emissions. In the case of electromagnetic problems, it is the
responsibility of the user to resolve the situation. It may be necessary to shield the equipment and fit
suitable filters on the mains supply.
4
5
LF Declaration
Consult the data plate on the equipment for the power supply requirements. Due to the elevated
absorbency of the primary current from the power supply network, high power systems affect the
quality of power provided by the network. Consequently, connection restrictions or maximum
impedance requirements permitted by the network at the public network connection point must be
applied to these systems. In this case the installer or the user is responsible for ensuring the equipment
can be connected, consulting the electricity provider if necessary.
Materials and their disposal
The equipment is manufactured with materials, which do not contain any toxic or poisonous
materials dangerous to the operator. When the equipment is scrapped, it should be dismantled
separating components according to the type of materials. Do not dispose of the equipment with
normal waste. The European Directive 2002/96/EC on Waste Electrical and Electronic Equipment states
the electrical equipment that has reached its end of life must be collected separately and returned to an
environmentally compatible recycling facility.
Handling of Compressed gas cylinders and regulators
All cylinders and pressure regulators used in welding operations should be handled with care.
Never allow the electrode, electrode holder or any other electrically “hot” parts to touch a cylinder.
Keep your head and face away from the cylinder valve outlet when opening the cylinder valve.
Always secure the cylinder safely. Never deface or alter any cylinder.
The following signs and explanations are to remind the user of the potential
risks involved and the dangers of misuse or mistreatment of the welding
machine.
!
RUNNING PARTS MAY BE DANGEROUS!
Keep away from running components,
including the fan.
BE AWARE OF SPARKS AND SPATTER
Wear protective clothing, such as leather
gloves, Flame retardant overalls, boots and
eyewear.
DO NOT TOUCH THERMAL COMPONENTS!

2. Installation
Unpacking
Check the packaging for any signs of damage. Carefully remove the machine and retain the packaging
until the installation is complete.
Location
The machine should be located in a suitable position and environment. Care should be taken to avoid
moisture, dust, steam, oil or corrosive gases. Place on a secure level surface and ensure that there is
adequate clearance around the machine to ensure natural airflow.
Input connection
Before connecting the machine you should ensure that the correct supply is available. Details of the
machine requirements can be found on the data plate of the machine or in the technical parameters
shown in the manual. The equipment should be connected by a suitably qualified competent person.
Always ensure the equipment has a proper grounding. Never connect the machine to the mains supply
with the panels removed.
Output connections
In general when using manual arc welding electrodes the electrode holder is connected to the positive

3. Operation
Before starting any welding activity ensure that you have suitable eye protection and protective
clothing. Also take the necessary steps to protect any persons within the area.
MMA
After connecting the welding leads as detailed you will need to switch the power switch on the back
panel to “ON” Select MMA by switching to the MMA welding mode. There is voltage output at both output
terminals. Set the amperage on the machine suitable for the electrode being used. Ensure you check that
you have the electrode polarity correct. Please see below a guide to amperages required.
MIG/MAG
Connect the MIG torch leads as detailed above. Ensure that a suitable inert gas supply is connected.
Switch the power switch on the back panel to “ON”, the machine is started with the power LED on and
the fan working. Switch the MMA/MIG switch to MIG mode. Select pull position if using a remote torch
Open the gas valve of the cylinder, and adjust the gas regulator to obtain the desired flow rate.
Adjust the “voltage control knob in MIG” and “wire feed speed control knob in MIG” on the front panel
of the machine to get the correct welding voltage and welding current. Operate the torch trigger, and
welding can be carried out. Where required adjust the burn-back time potentiometer (above the feed
unit inside the machine) to get the proper electrode stick-out. One second after the arc stops, the gas
supply will be cut off.
Gas selection
Metal inert gas welding (MIG): Uses Argon (Ar), Helium (He) or Ar-He mixtures as the shield gas, and
it mainly used for welding aluminium and its alloys. Metal active gas welding (MAG): Uses Argon (Ar)
mixed with a certain amount of CO2 / O2 as the shield gas, and it usually used in short circuit transfer
and spray transfer. It can be applicable to flat position welding, vertical position welding, overhead
position welding and all-position welding, and it mainly used for welding carbon steel, high strength
low alloy steel and stainless steel. Welding robots mostly use the MAG process. CO2 (carbon dioxide)
gas shielded arc welding (CO2 welding): It uses CO2 as the shield gas, and is usually used in globular
transfer and short circuit transfer to implement welding. It can be used to weld in different positions. As
compared with other welding methods, CO2 welding has many advantages, though it produces more
spatters, CO2 welding is widely used for general metal structure welding.

1) Welding current setting
Set the welding current after the above preparation. Short circuiting transfer is mainly fit for electrode
wires of diameter 0.6~1.2mm. As a guide for short circuit welding set the welding current according to
the table below.
2) Welding speed selecting
The welding quality and productivity should be taken into consideration for the selecting of welding
speed. In the case that the welding speed increases, it weakens the protection effect and quickens the
cooling. As a consequence, it is not good for weld bead shaping. In the event that the speed is too slow,
the work-piece will be burned through, and a good weld bead will be unavailable. In practical operation,
the welding speed should not exceed 50cm/min.
3) Wire Stick-out
The increase of the stick-out can improve the productivity, but too long stick-out may lead to excessive
spatter, wire breaking and unstable welding. Generally, the stick-out should be 10 times as the welding
wire diameter.
4) Shield gas flow selection
The protection effect is the primary consideration. Besides, the protection effect of inner-angle welding
is better than that of external-angel welding, so the gas flow in inner-angle welding should be lower.
Less or no shield gas is needed in FCAW. Refer to the table below for the recommended gas flow rates.
