Operation Steps of Pulse TIG Welding
- Connect the welding machine to the input power supply and power the welding machine on. In
such case, power on the machine and let it have a self-check; and the screen will display: Full
display->HYL->Model such as 200-> Enter the previous welding status.
- Press the TIG/MMA function selector switch, then the pulse TIG indicator will be on and the weld
-
ing machine will change into the pulse TIG status.
- Press the parameter setup selector key to set welding parameters such as pre-flow time, arc strik
-
ing current, rise time, given current, fall time, arc stopping current, after-flow time, etc; with the
regulation knob (2), you may respectively adjust the above parameters.
- Press the 2T/4T selector key to choose 2T or 4T.
- In welding, you may adjust the welding parameters. The 2T/4T and the welding mode cannot
be switched.
- After regulating the welding current, save such welding parameter as unit n; forthe next use, you
may directly call the parameters in the storage unit n.
- After the welding is over, turn off the power switch and then disconnect the input power.
- Wrong code indicator : Over-heating : OH ,Over-current : OC

Operation steps of MMA mode
1. Turn on power to the box, fan starts to work.
2. Press the TIG/MMA function selector switch, then the MMA indicator will be on and the welding
machine will change into the MMA status.
3. With the regulation knob select a proper welding current. The experimental expression for weld
-
ing current selection is I=40XD, where, D is the diameter of the used welding rod in mm.

Parameter Storage
- Press the parameter storage function key [SAVE key] to enter the storage status, then the screen
will display SA..n;
- With the regulation knob (2), select the storage unit n whose scope is 0-9.
- Press the parameter storage function key again; when the welding parameters are to be saved
into the target storage unit n, then the screen will display to.n.; after flashing 3s, n will return to
the status before storage.

Call parameters
- Press the parameter call function key [PROG key] to enter the call status, then the screen will
display rd..n;
- With the regulation knob (2), select the saved unit n
- Press the parameter call function key again, then the welding parameters of the storage unit n
will be read and cover the current status, and the screen will display Fr.n; after flashing 3s, n will
return to the storage status. .
- In the process of stored parameter call, if failing to press the key to confirm, press any other key
