7. OPERATION NOTICES
Environments
(1) Welding should be done in relatively dry environments, the air humidity should be no
more than 90%. Welding environment temperature should be between -10
0
C~40
0
C.
(2) Avoid operating the machine in sunlight or rain, do not let water or rain water infiltrate
the welding machine.
(3) Avoid welding operation in dusty areas or under corrosive gas environment.
(4) Avoid gas welding in strong air flow environments.
Safety
TIG series has been installed in over voltage, over current and over heat protection circuits, when
the grid voltage, input current and the internal temperature exceeds the set standards, the
welding machine will automatically stop working; but excessive use will cause damage to the
machine, so you need to note the following safety items:
(1) To ensure good ventilation to this kind of small welding machine, there will be greater
current through over when working while the natural ventilation is not enough to meet
the cooling requirements of welding, so it needs to equip with a fan to cool the machine
effectively and help it to work stably. The operator should ensure good ventilation, other
surroundings should keep at least 0.3 meters away from the machine, as it is very
important to help the machine has better performance and longer using life.
(2)
To prohibit the over-load or over-voltage The operator should keep observing the Max.
permited load current (corresponding to the selectable duty cycle), to ensure the welding
current not exceed the Max. permited load current, as over current will obviously reduce
the life of the welding machine or even burn the machine; Supply voltage listed in the
“Parameters sheet”; In general cases, the voltage automatic compensation circuit inside
the machine will ensure that the welding current within the permitted range. If the
voltage exceeds the allowable value, the machine will be damaged.
(3) There is a ground screw marked with ground markers at the back of each welding
machine. Before operating, use an earth cable larger than 6.0mm
2
to connect with the
machine to avoid discharging any static electricity or to prevent leakage accidents.
(4)
If the welding machine works over the duty cycle, it may suddenly stop working and into
protected status, this means the load exceeds the standard duty cycle, and the excessive
heat triggers the temperature control switch so that the machine stops working and the
alarm indicator on the front panel lights at the same time. In this case, you need not to
disconnect the power plug, so as to keep the fan working to cool the machine. When the
alarm indicator lights off, the temperature drops to a standard extent, then you can
restart welding.
