THANK YOU FOR YOUR PURCHASE
Weldco would like to thank you for purchasing the Inverter AC DC TIG and MMA welder.
This manual is designed to guide you through using your new machine.
Your Weldco inverter welder utilizes the latest in welding technology to ensure you receive excellent results in a
variety of applications.
UNPACKING YOUR WELDER
Contents:
•Welding Power source.
•4m Variable amp TIG Torch.
•Earth clamp and lead.
•Twist style holder and lead.
•TIG torch consumables (not pictured).
Please check all contents are correct and damage free before first use, if any issues please contact your
local dealer.
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.
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 125 amps the welder will TIG weld continuously for 6 mins and needs to rest for 4 mins.
•At 100 amps the welder will TIG weld 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 TIG 200 ACDC is fitted with a 15amp plug. This machine is designed to work with 15amp 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.

Torch Trigger Control
2T Trigger Control.
• Press the torch trigger and hold.
• The set pre-gas flows and the arc will start, upsloping to the set amperage.
• To finish the weld, release the trigger the amperage will begin to downslope at
the preset rate. If downslope set to zero, the arc will instantly stop.
4T Trigger Control.
• Press the torch trigger and hold.
• The set pre-gas flows and the arc will start. (Start Current).
• Release the trigger and the amperage will upslope to the preset amperage.
•To finish the weld, press and hold the trigger, the amperage will begin to downslope at
the preset rate and hold at the preset end current.
• Release the trigger again and the arc will stop, and the post flow will continue
for the preset time.
