SAFETY INSTRUCTION
Safety against fumes and welding gases
The HSE have idened welders as being an ‘at risk’ group for occupaonal diseases arising
from exposure to dusts, gases, vapours and welding fumes. The main idened health eects
are pneumonia, asthma, chronic obstrucve pulmonary disease (COPD), lung and kidney
cancer, metal fume fever (MFF) and lung funcon changes.
During welding and hot cung ‘hot work’ operaons, fumes are produced which are
collecvely known as welding fume. Depending upon the type of welding process being performed, the
resultant fume generated is a complex and highly variable mixture of gases and parculates.
Regardless of the length of welding being carried out, all welding fume, including mild steel welding
requires suitable engineering controls to be in place which is
usually Local Exhaust Venlaon (LEV) extracon to reduce the
exposure to welding fume indoors and where LEV does not
adequately control exposure it should also be enhanced by using
suitable respiratory protecve equipment (RPE) to assist with
protecng against residual fume.
When welding outdoors appropriate RPE should be used.
Prior to undertaking any welding tasks an appropriate risk
assessment should be carried out to ensure expected control
measures are in place.
Locate the equipment in a well-venlated posion and keep your head out of the welding fume.
Do not breathe in the welding fume.
Ensure the welding zone is well-venlated and provision should be made for suitable local fume
extracon system to be in place.
If venlaon is poor, wear an approved airfed welding helmet or respirator.
Read and understand the Material Safety Data Sheets (MSDS’s) and the manufacturer’s instrucons for
metals, consumable, coangs, cleaners and de-greasers.
Do not weld in locaons near any de-greasing, cleaning or spraying operaons.
Be aware that heat and rays of the arc can react with vapours to form highly toxic and irritang gases.
For further informaon please refer to the HSE website www.hse.gov.uk for related documentaon.
Precauons against re and explosion
Avoid causing res due to sparks and hot waste or molten metal.
Ensure that appropriate re safety devices are available near the welding and cung area.
Remove all ammable and combusble materials from the welding, cung and surrounding
areas.
Do not weld or cut fuel and lubricant containers, even if empty. These must be carefully
cleaned before they can be welded or cut.
Always allow the welded or cut material to cool before touching it or
placing it in contact with combusble or ammable material.
Do not work in atmospheres with high concentraons of combusble
fumes, ammable gases and dust.
Always check the work area half an hour aer cung to make sure that
no res have begun.
Take care to avoid accidental contact of the torch electrode to metal
objects, as this could cause arcs, explosion, overheang or re.
Know and understand your re exnguishers

SAFETY INSTRUCTION
The working environment
Ensure the machine is mounted in a safe and stable posion allowing for cooling air circulaon.
Do not operate equipment in an environment outside the laid down operang parameters.
The welding power source is not suitable for use in rain or snow.
Always store the machine in a clean, dry space.
Ensure the equipment is kept clean from dust build up.
Always use the machine in an upright posion.
Protecon from moving parts
When the machine is in operaon keep away from moving parts such as motors and fans.
Moving parts, such as the fan, may cut ngers and hands and snag garments.
Protecons and coverings may be removed for maintenance and managed only by qualied
personnel aer rst disconnecng the power supply cable.
Replace the coverings and protecons and close all doors when the intervenon is nished and before
starng the equipment.
Take care to avoid geng ngers trapped when loading and feeding wire during set up and operaon.
When feeding wire be careful to avoid poinng it at other people or towards your body.
Always ensure machine covers and protecve devices are in operaon.
Risks due to magnec elds
The magnec elds created by high currents may aect the operaon of pacemakers or
electronically controlled medical equipment.
Wearers of vital electronic equipment should consult their physician before beginning any arc
welding, cung, gouging or spot welding operaons.
Do not go near welding equipment with any sensive electronic equipment as the magnec
elds may cause damage.
Keep the torch cable and work return cable as close to each other as possible throughout their length.
This can help minimise your exposure to harmful magnec elds.
Do not wrap the cables around the body.
Handling of compressed gas cylinders and regulators
Mishandling gas cylinders can lead to rupture and the release of high pressure gas.
Always check the gas cylinder is the correct type for the welding to be carried out.
Always store and use cylinders in an upright and secure posion.
All cylinders and pressure regulators used in welding operaons 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 and never move with regulator and hoses connected.
Use a suitable trolley for moving cylinders.
Regularly check all connecons and joints for leaks.
Full and empty cylinders should be stored separately.
Never deface or alter any cylinder

SAFETY INSTRUCTIONS
Fire awareness
The cung and welding process can cause serious risks of re or explosion.
Cung or welding sealed containers, tanks, drums or pipes can cause explosions.
Sparks from the welding or cung process can cause res and burns.
Check and risk assess the area is safe before doing any cung or welding.
Venlate all ammable or explosive vapour from the workplace.
Remove any and all ammable materials away from the working area. If necessary, cover ammable
materials or containers with approved covers (following manufacturers instrucons) if unable to remove
from the immediate area.
Do not cut or weld where the atmosphere may contain ammable dust, gas or liquid vapour.
Always have the appropriate re exnguisher nearby and know how to use it.
Hot parts
Always be aware that material being cut or welded will get very hot and hold that heat for a
considerably long me which will cause severe burns if the appropriate PPE is not worn.
Do not touch hot material or parts with bare hands.
Always allow for a cooling down period before working on material recently cut or welded.
Use the appropriate insulated welding gloves and clothing to handle hot parts to prevent burns.
Noise awareness
The cung and welding process can generate noise that can cause permanent damage to your
hearing. Noise from cung and welding equipment can damage hearing.
Always protect your ears from noise and wear approved and appropriate ear protecon if
noise levels are high.
Consult with your local specialist if you are unsure how to test for noise levels.
RF Declaraon
Equipment that complies with direcve 2014/30/EU concerning electromagnec compability
(EMC) and the technical requirements of EN60974-10 is designed for use in industrial buildings
and not for domesc use where electricity is provided via the low voltage public distribuon
system.
Dicules may arise in assuring class A electromagnec compability for systems installed in domesc
locaons due to conducted and radiated emissions.
In the case of electromagnec problems, it is the responsibility of the user to resolve the situaon.
It may be necessary to shield the equipment and t suitable lters on the mains supply.
LF Declaraon
Consult the data plate on the equipment for the power supply requirements.
Due to the elevated absorbance of the primary current from the power supply network, high
power systems aect the quality of power provided by the network. Consequently, connecon
restricons or maximum impedance requirements permied by the network at the public network
connecon point must be applied to these systems.
In this case, the installer or the user is responsible for ensuring the equipment can be connected,
consulng the electricity provider if necessary.

LCD SCREEN ICON FUNCTION DESCRIPTIONS
Selecon and adjustment of welding parameters
The central ‘master’ encoder can switch and adjust all parameters. When and if a box, number or opons
on the LCD screen is highlighted green, it indicates the parameter can be adjusted with the master
encoder sand they display in a grey colour this indicates that the parameter cannot be adjusted.
1. Adjustment of main welding parameters:
In the welding working page, the current, wire feed speed and voltage can be adjusted by rotang
three knobs, respecvely.
In MIG mode, the lower le control dial (item 1 page 15) can adjust the welding current or wire feed
speed and the lower right control dial (item 16 page 15) will adjust the welding voltage or arc length,
where as rotang and pressing the central master encoder will adjust, set and scroll through all the
available parameters.
In MMA or Li TIG mode, the current can only be adjusted by the master encoder.
2. Adjustment of other welding parameters:
Except for current and voltage, all other parameters can only be adjusted in "Parameter Sengs",
which are detailed in the following table.
