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 welding machine will change into the pulse TIG status.
- Press the parameter setup selector key to set welding parameters such as
foreblow time, arc striking current, rise time, given current, fall time, arc stopping
current, afterblow 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; for
the 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 welding current selection is I=40D, 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
