Water Cooling
The welding machine is supplied standard with water cooled TIG torch. The correct
coolant to use is a mixture of Mono Propylene Glycol and water in a 1:3 ratio (25%
propylene glycol). Pure water may be used as a coolant liquid, though it is not
recommended for the long term reliability of the water cooling system as it does not
have the lubrication properties of glycol and does not provide protection against
freezing. Ready to use coolant fluid can be purchased from authorised dealers.
Do not operate a water cooled torch without the cooling system operating!

Connection
The TIG series of welding machines is designed to operate on a110V /220V AC
power supply. When the power supply voltage is over the safe work voltage, there
are over voltage and under voltage protection inside the welder, the alarm light will
on, at the same time, the current output will be cut off.
If the power supply voltage continually goes beyond the safe work voltage range,
it will shorten the welder life-span. The below measures can be used:
-
Change the power supply input net. Such as, connect the welder with the stable
power supply voltage of distributor;
-
Induce the machines using power supply in the same time;
-
Set the voltage stabilization device in the front of power cable input.
Connection of Output Cables
Two sockets are available on this welding machine. For MMA welding the electrode
holder is shown be connected to the positive socket, while the earth lead
(work piece) is connected to the negative socket, this is known as DCEP. However
various electrodes require a different polarity for optimum results and careful
attention should be paid to the polarity, refer to the electrode manufacturers
information for the correct polarity.
DCEP: Electrode connected to “+”output socket.
DCEN: Electrode connected to“-” output socket.
MMA (DC) : Choosing the connection of DCEN or DCEP according to the different
electrodes. Please refer to the electrode manual.
MMA (AC) : No requirements for polarity connection.
