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.

11
•Set the spool brake tensioner by tightening or loosening the wire spool retaining nut.
Set the spool brake tension so that the spool can rotate freely, without continuing to rotate once the wire feed stops.
Check performance from time to time to ensure that the wire is feeding correctly, especially as the wire spool empties.
WIRE FEEDER
•Release the wire feeder tensioner arm (6) by pulling forward the tension adjustment knob (5).
Check the drive roller matches the wire type and wire diameter (size is stamped on the side of the roller).
“V”groove roller for solid hard gas shield wires –Mild steel and Stainless Steel.
“Knurled”roller for gasless/flux core.
To change the roller, undo the roller retainer bolt (7), slide off the roller, replace with the correct roller making sure
that the correct size groove lines up with the inlet guide tube (9). Tighten the retaining bolt anticlockwise, hand tight.
•Whilst holding the wire spool (this will prevent the spool uncoiling) carefully snip the wire and feed through the inlet
guide tube (9), over the roller and into the torch liner, feeding the wire approximately 50mm into the torch liner as this
will assist in feeding the wire through the torch.
•Align the wire into the grove of the roller and close the wire tensioner arm (6) and adjust the wire feed tensioner (5)
making sure the wire remains in the groove.
•Adjust the wire feed tension (5) by turning clockwise to increase the tension and anti-clockwise to reduce. Do not over
tighten the tension, the wire will be crushed –especially soft wires and flux cored wires.

12
SETUP FOR GASLESS MIG WELDING
Please ensure you have all relevant safety equipment and PPE ready.
•Check that the correct gasless (Flux cored) wire, drive roller (8) and welding tip are fitted.
•Connect Polarity cable (3) to the Negative Terminal (2).
•Connect Earth Lead to the Positive Welding Terminal (1).
•Connect Earth Clamp to the work piece. It is important the earth clamp makes strong contact with bare metal –remove
paint, rust or other contaminates to ensure strong contact. Failure to do so will reduce your welding performance.
•Ensure the main power switch is in the OFF position. Plug the 10amp plug into the 10amp wall socket. Turn power to
the ON position on both the wall socket and the power source. The front panel will illuminate, and the cooling fan will
start.

MIG Synergic setup
•Select MIG Synergic (18) by pressing the welding process selector (15) the MIG SYN light will light up.
•Remove the welding nozzle from the torch in a clockwise twisting action (this ensures the tip adaptor spring remains
tight) and then remove the welding tip, press and hold the trigger on the welding torch this will run the wire feed
motor to push the wire through the torch. Once the wire comes out of the torch release the torch trigger stopping the
wire feed motor.
•Reinstall the welding tip ensuring the correct tip is selected (same size as the wire or one size larger) and reinstall the
nozzle again using a clockwise twisting action.
•Your MIG165 MIG synergic mode, removes the guess work out of selecting the right combination of VOLTAGE and
WIRE SPEED. Once you have selected MIG Synergic increasing or decreasing dial (13) will adjust both the voltage (heat)
and Amperage (wire speed m/min). The voltage will be displayed on voltage display screen (11) and your Amperage on
the amperage display screen (12).
•Adjusting the synergic curve up or down will fine tune your welder’s performance (finding the sweet spot). Turn the
dial (14) clockwise this will increase VOLTAGE only (increasing heat to the weld pool but not wire speed), turning the
dial anti-clockwise will reduce the VOLTAGE only cooling the weld pool (effectively increasing wire speed). Once you
have found the sweet spot use dial (13) to adjust the welder for increased thickness on thinner plate.
MIG Manual setup
•To adjust your voltage and wire speed individually, select MIG Manual by pressing the Step selector (15).
•Remove the welding nozzle from the torch in a clockwise twisting action (this ensures the tip adaptor spring remains
tight) and then remove the welding tip, press, and hold the trigger on the welding torch this will run the wire feed
motor pushing the wire through the torch. Once the wire comes out of the torch release the torch trigger stopping the
wire feed motor.
•Reinstall the welding tip ensuring the correct tip is selected (same size as the wire or one size larger) and reinstall the
nozzle again using a clockwise twisting action.
•The voltage will be displayed on the voltage display screen (11) and your Amperage (wire speed) on the amperage
display screen (12).
To increase or decrease voltage (heat), adjust the voltage adjustment dial (14) the higher the voltage the thicker the
material and hotter the weld pool. To adjust the wire speed, turn the Amperage adjustment dial (13) to the required
setting.
It is recommended that the welding voltage is first set and then slowly adjust the amperage (wire speed) until the arc is
stable and smooth. Once this is achieved if the voltage is too high (hot –burning through) or two low (cold –lacking
penetration) adjust the voltage again and repeat this process.
With your PPE on, you are ready to start welding. Ensure to adjust your settings to receive optimal results.

14
SETUP FOR GAS MIG WELDING
Please ensure you have all relevant safety equipment and PPE ready.
•Connect the optional Weldco Argon Regulator (WDC0812) to the argon cylinder or CO2 cylinder and connect the
gas line to the regulator.
•Connect the gas line from the regulator to the gas inlet on the back panel of the welder.
•Open the valve on the cylinder and set your gas flow rate between 5-10L/min. It is good practice to test for leaks.
Close the cylinder valve. If there are no leaks the regulator will maintain the set L/min and cylinder pressure values.
Always turn off your cylinder valve when not in use.
•Check that the correct gas shield wire, drive roller (8) and welding tip are fitted.
•Connect Polarity cable (3) to the positive + welding output terminal (1).
•Connect Earth Lead to the negative -output welding terminal (2).
•Connect Earth Clamp to the work piece. It is important the earth clamp makes strong contact with bare metal –

SETUP FOR MMA (STICK) WELDING
Please ensure you have all relevant safety equipment and PPE ready.
This setup is for the most common electrode positive setting for General purpose rods. Please check your electrode packaging
to confirm.
•Connect the earth clamp cable into the  NEGATIVE (3) terminal on the front of the machine. Connect the Earth clamp
to the work piece. It is important the earth clamp makes strong contact with bare metal – remove paint, rust or other
contaminates to ensure strong contact. Failure to do so will reduce your welding performance.
•Connect the electrode holder cable into the + POSITIVE (2) terminal on the front of the machine.
Ensure that the plug is secure in the socket to reduce any chance of arcing from loose connection
•With the main power switch is in the OFF position. Plug the 10amp plug into the 10amp wall socket. Turn power to the

17
•Once the machine has powered up press the welding process selector (11) to select MMA.
•Your Weldco Inverter welder is fitted with a “Voltage Reduction Device” (VRD) (16)
The VRD reduces the open circuit voltage to safer levels. The VRD default is OFF. To activate the VRD press the welding
process selector (15) to select VRD.
•Adjust the welding current to the relevant level for the welding electrode type and size, as per the electrode
manufacturer by adjusting the amperage adjustment dial (13).
•Insert the electrode into the electrode holder. Once the electrode contacts the work piece (also any metal connected to
the work piece) the electrode will strike an arc, for this reason do not rest the fitted electrode on the work area.
•With your PPE on, strike the work piece with the electrode (like striking a match) hold the electrode slightly off the
work piece to maintain a constant arc.
•To stop the weld, quickly lift the electrode from the work piece (stopping the electrical circuit).
•It is important to chip away the “SLAG” before continuing to weld and for weld inspection, Allowing the weld to cool
slightly will make “SLAG” removal easier. It is important to wear eye protection whilst removing the “SLAG”.
