TIG Inverter Instruction Manual
Welding and cutting is dangerous to the operator, people in or near the working area, and the
surrounding environment. Therefore, the performance of welding and cutting must only be done
under the strict and comprehensive observance of all relevant safety regulations. Please read and
understand this instruction manual carefully before installation and operation.
•Switching function modes during welding could potentially damage the equipment.
•Disconnect the electrode-holder cable from the equipment before welding.
•A safety switch is necessary to prevent the equipment from electric-leakage.
•Use only high quality welding tools and equipment with this Inverter.
•Operators should be suitably trained to use this equipment.
Warning
Electric Shock
•Connect the earth cable according to standard regulation.
•Avoid any contact with live components of the welding circuit, electrodes
and wires with bare hands. The operator should wear suitable welding
gloves while using this machine.
•The operator should keep the work piece insulated from himself/
herself.
Smoke and Gas generated while welding or cutting
•Avoid breathing in smoke and gas from welding or cutting.
•Make sure you are working in a well ventilated area.
Arc light-emission
•Always wear a welding helmet and appropriate work clothes while
welding.
•Measures should also be taken to protect people in or near the area
you are working.
Fire hazard
•Sparks from welding may cause re. Remove any ammable items from
the immediate area before welding.
•Have a re extinguisher nearby.
Noise
•Surface noise is generated while welding and cutting. Use suitable
hearing protection.
Machine Fault
•Consult this instruction manual in the case of a fault.
•Contact your local dealer or supplier for further advice.

This welding machine is manufactured with advanced inverter technology. With power component
MOSFET and PWM technology, the inverter converts DC voltage, which is rectied from input
AC voltage, to high 100KHz frequency AC voltage; as a consequence, the voltage is transformed
and rectied. Therefore, it results in a smaller transformer and lighter inverter machine, which
increases welding performance by 30%. The high frequency oscillation, which enables the output
of high frequency DC, is employed in the arc-starting system. The features of this product are as
follows: stable current, reliable, fully portable, ecient and quiet in operation.
When MMA welding, this welding machine features stable output and the option of arc force.
In case of normal arc input voltage, the stability of welding current output is not compromised
with variation of arc length, therefore it results in a stable performance of welding operation. In
the case of low input voltage, welding output current increases while arc voltage decreases, as
a consequence, the length of arc, which is not sucient, will automatically compensate and the
modulation of arc force is accessible. In case of the input arc voltage being too low to maintain
arc, the output of this welding equipment descends steeply, which avoids the splash generated
due to over current input.
When TIG welding, this welding equipment features stable output current and that the welding
current output does not change with the variation of the length of arc. In case of short circuit of
electrode, the voltage automatically decreases to 0V, which limits the impairment of electrode
and pollution to environment.
Warranty of maintenance for main components is one years.
During the warranty maintenance period, all maintenance is free of charge, not including any
deliberate damage or alteration to this welding equipment.
In the case of a fault with the inverter machine, only qualied electricians are authorized to carry
out repairs.

Please note: Any extension of mains cables or torch cables may aect the performance of this
welding equipment. Input voltage is decided by the length of the cable, therefore longer than
standard cables will reduce the amount of resistance. It is recommended to maintain the standard
length of main cables and torch cables.

Caution
1. Working Environment
1.1 The location in which this welding equipment is installed should be free from dust, corrosive
chemical gas, ammable gas or materials, and a maximum of 80% humidity.
1.2 Avoid the operation of welding in the open air unless the working area sheltered is from the
elements. The ambient temperature of the working environment should be maintained within
–10°C to +40°C.
1.3 Allow a distance of at least 300mm (12”) between this machine and any walls.
1.4 Make sure the area you are working in is well ventilated.
2. Safety Tips
2.1 Ventilation: Good ventilation is of critical importance for the performance and service life of
this inverter welding machine. Maintain a minimum distance of 30cm (12”) between the inverter
machine and any other objects in or near the working area.
2.2 Do not operate this machine when the O.C. Light is lit.
A sudden halt may occur while the welding operation is carried out while this welding machine is
in over-load status. Under this circumstance, it is unnecessary to restart this welding equipment.
Keep the built-in fan working to bring down the temperature inside this welding equipment.
2.3 This welding equipment uses automatic voltage compensation, which enables the
maintaining of the voltage range within the given range. In case the voltage of input power

supply current exceeds the stipulated value, it is possibly damaging to the components of this
welding equipment.
2.4 An earth terminal is available for this welding equipment. Connect with the earth cable to
avoid static and electric shock.
2.5 DO NOT contact the output terminal when the welding operation is performed. An electric
shock will occur.
Maintenance
Exposure to extremely dusty, damp, or corrosive air is damaging to this machine. In order to
prevent any possible failure or fault of the inverter, clean any dust at regular intervals with
compressed air.
Please note: Proper maintenance should be carried out by a skilled and qualied electrician on
a regular basis. Any attempts by an unauthorised or unskilled individual to remove the outer
casing, or conduct repairs or modications to the machine will void the warranty.
