WELDING HAZARDS AND SAFETY
Welding poses a variety of hazards to health and safety. Please ensure you have correct safety equipment for yourself and those
within the welding area. Your local distributor will be able to assist you with the correct Weldco protective helmet and gloves.
Detailed documents can be located on the Worksafe website, www.worksafe.govt.nz, topic welding.
WORK AREA
•Ensure your work area is clear, dry, and free of trip hazards.
•That the area is well ventilated, and all flammable materials are removed to a safe distance.
•Never leave your welder powered up – unattended.
FIRE RISK
•Due to the welding process producing molten metal including sparks and fumes maximum fire safety must always
be obeyed. Ensure you have direct access to the correct fire extinguisher for your environment.
•Never weld tanks or containers that have or have held flammable liquid, gas or where the contents are under
pressure. This should only be carried out by trained specialists.
•Ensure that the area is checked for smoldering materials as material will remain hot well after welding.
ELECTRICITY CAN KILL
•Never weld or attempt to weld in a wet or raining environments. There is a serious risk of electrocution to the
operator or those within the area.
•it is recommended that the welder be connected to an RCD.
FUMES AND GASES
•Welding produces fumes and gases that can be harmful to the operator and those within the surrounding areas.
Always ensure that there is plenty of ventilation and fresh air.
•Do not weld material that has been coated or contaminated with paint, varnish, or rubber as they may give off
harmful fumes or gas and increase the risk of fire and or explosion.
PERSONAL PROTECTIVE EQUIPMENT AND CLOTHING
The user must comply with occupational health and safety rules and wear appropriate protective equipment.
BURNS
•The welding process causes the work piece and surrounding items to become hot.
•It is always recommended that flame resistant clothing be warn.
•Welding gloves must be worn to help prevent burns to hands and arms when handling hot objects.
•Avoid skin exposure to the Ultraviolet rays produced by the arc. It is recommended that skin be protected from
these harmful rays. Serious burns are possible when this recommendation is not followed.
•Approved welding helmets must be worn by the operator and any personnel with in 10m of the work area. It is also
recommended that welding safety screens are installed to protect.
•It is always recommended that enclosed footwear with rubber soles be worn to protect from sparks and molten
metal and to reduce the risk of electrocution.
•As welding produces gases and fumes many of these can be harmful it is recommended that the operator and
these in the direct area wear respirators with the relevant protection.
•Always where safety glasses when chipping the slag, scraping, or preparing the work piece.
5
ELECTROMAGNETIC AND RADIO FREQUENCIES – “PACEMAKERS”
•Avoid contact with the energized work piece.
•Always ensure you have adequate protection from electrocution and burns.
•Since the welder owns strong electromagnetic and radio frequencies. Persons fitted with “PACEMAKERS” or similar
devices MUST consult their doctor before turning on the welder. This relates to both the operator and those
nearby.
PRE-CHECKS
The following items must be checked by the operator each time before powering up the power source.
•Ensure that the welder is damage free and no exposed wires.
•Check all welding cables, insulation and accessories are free of damage.
•The work area is checked and free of hazards
•All personal protective clothing and equipment is defect free.
•Access to Fire extinguisher and welding blanket.
•All flammable material has been removed.
WARNING!
•Disconnect the power source before servicing and ensure the device has powered down.
•Contact your dealer or reseller immediately should your welder require servicing.
•It is not recommended that you remove the covers to carry out your own servicing – doing so will void the
warranty.
STORAGE, TRANSPORTATION AND MAINTENANCE
•Your welder contains sensitive electronics and needs to be stored in a dust and moisture free environment.
•Periodically your welder should be blown down using dry compressed air to remove any dust and metal fillings.
•Once your power source and welder have cooled down. Remove your accessories for storage – wipe both the welder
and accessories down with a clean cloth to remove any contaminates.
•Store your welder in a dry safe environment.
•When transporting ensure that the power source, accessories, and wire are secure.
•Cylinders need to be stored and transported as per NZ regulations and safe operating procedures.

TECHNICAL DESCRIPTION
COMPLIANCE PLATE
Duty Cycle
The welder’s duty cycle is the number of minutes in a 10-minute period the power source can safety produce the set
welding current (actual arc on). If this is exceeded the machine will enter thermal overload, turning the welding current off
protecting the welder. This is indicated by the light on the front panel. The fan will continue to cool the power source
during thermal overload.
For example:
•At 80 amps the welder will MIG continuously for 6 mins and needs to rest for 4 mins.
•At 62 amps the welder will MIG continuously or 100% of the time.
The duty cycle is tested at 40 degrees Celsius, if the welder is operating in lower temperature e.g., 20 degrees Celsius the
duty cycle will be higher.
INPUT PLUG
The MIG165 is fitted with a 10amp plug. This machine is designed to work with 10amp domestic wall sockets. It is important
that the machine is plugged directly into the mains plug. If an extension cord must be used a minimum 2.5mm wire thickness is
required and no more than 10m in length.
Using unsuitable extension cords will reduce the input voltage (known as voltage drop) and this will void the warranty of your
machine.
OPERATING ENVIRONMENT
•Operating temperature: -10℃~40℃.
•Transportation and storage: -25℃~55℃.
•Relative air humidity: 40℃ ≤ 50%; 20℃ ≤ 90%.
•The dust, acids, corrosive gases, and substance in the ambient air must be not higher than normal level.
•Altitude must be less than 1km.
•Good ventilation around the machine, at a distance of at least 50cm around.
•Power source must be kept on a level surface to reduce the risk of the machine falling.

SETUP FOR GAS OR GASLESS MIG WELDING
Smooth consistent wire feed is critical to achieve professional results.
FITTING THE WIRE
•Open the side cover door for the wire feed compartment.
Remove the wire spool retaining nut (4), tensioner spring and
flange.
•Fit either the 5Kg/200mm or 1Kg/100mm diameter wire spool to the spool holder. Ensure the end of the wire feeds
towards the drive rollers from the bottom of the spool.
•Align the wire spool flange, tensioner spring and tighten the retaining nut.
