The state light of heat protection is on when the machine has over-heated. Let the machine on so that
the fan will cool the machine. Wait until the light goes off, and you can continue welding.
The state light for wrong voltage turns on if the mains voltage is too high or too low. Check the mains
voltage. The wrong voltage light will also turn on if there is a momentaneous over-voltage or
under-voltage in the mains supply.
1.4. Welding mode choose and indicator
Type of machine can be chosen among HFTIG, LIFTTIG and MMA by
press option keys with yellow arrow, at the same time the indicator of type
of machine light up.
Under TIG mode the Pulse Switch, Processing Selection and function of
parameters’ save and usable will be available.
1.5. MMA Welding
->1.Under mode stick welding, you can press button
Parameter Selection and choose Welding Current, Hot
Start and Arc Force. At same time the corresponding
parameters’ indicator light up.
->2.The previous chosen parameters can be adjusted by
turning coding knob, at the same time the current
parameters can be written on the digital panel.
Note: Adjustment of Hot Start is for hot arc current.
Adjustment of Arc Force is for percentage.
1.6. TIG Welding
1.6.1. Pulse Switch
Under TIG mode, you can press buttons on the left icon to start and
cancel pulse function. When Pulse indicator lights up the pulse function
is available and when the indicator snobs out the pulse function is
unavailable. When the Pulse function is available, the Peak Current,
Base Current, Pulse Frequency and Pulse Ratio functions are available
and can be adjusted.
1.6.2. Operation Selection
Under TIG mode, you can press buttons on the left icon to choose 2T
or 4T. Under 4T mode, the Ignition Current, Up Slope, Down Slope and
Crater Current are available and can be adjusted. How to operate the
2T and 4T as following:
