Pulsed welding with unfixed frequency (the cycle is 1/5
of the upslope time) and fixed duty cycle (50%):
The same with that of mode 18.
When reading the above table, please note:
Whether arc ignited by HF or by striking the electrode, and no matter what kind of operation mode is selected,

after arc is ignited successfully, it enters into initial current, and later into operational mode control.
Some operation modes adopt the exit mode by pushing the torch trigger. The operator should release it after

exiting welding. In this way, another welding operation can be entered by pushing the torch trigger.
Current curves in all operation modes are drawn on the assumption that the machine works in DC TIG mode. If

the machine works in pulsed TIG mode, the current curve appears a pulse shape; if the machine works in AC
TIG mode, the current curve appears a variable polarity pulse shape.
Customarily, the TIG operation modes most widely used are 2T and 4T, which exactly correspond to operation

mode 2 and 4 for this machine respectively.
Use the operation mode programming function carefully, since it is somewhat difficult.

5.7 Installation and operation in TIG
5.7.1 Installation in TIG
Note:
1. When in DC/pulsed TIG, the connection showed above is DCEN polarity. For DCEP polarity, exchange the
plugs of the TIG torch and work clamp and insert into the corresponding output terminal, but it is only used in
welding on some special materials. When in AC TIG welding, install the machine according to the above figure.
2. Pay special attention to the marks for the output sockets and the like on the front panel: The ones in circle are
needed in TIG, and the ones out of circle are needed in SMAW.

Users prepare input gas
hose, gas regulator,
cylinder and switching box
by themselves.

In AC TIG welding, welding
cable shouldn't be longer than
10m (i.e. the output circuit
shouldn't be longer than 20m)
and don't t twist it. Otherwise,
the machine will be damaged.
