Preparation for Work - 4
2- Attach the electrode to the electrode clamp.
3- Connect the work clamp to a clean place on the work piece free of paint or rust with the jaws in
complete contact.
4- Insert the input cable to a suitable mains supply.
5- Perform the following checks before starting the welding procedure:
a- Make sure that the welding machine is grounded securely.
b- Make sure that all contact surfaces, especially the contact between the work clamp and work
piece are well secured.
c- Check that the welding cables are attached correctly.
d- The particles and sparks splashing around while welding may cause a fire. Therefore, make
sure that no flammable materials are present in the welding area.
6- Turn on the On/Off switch (11).
7- Adjust the ‘Coated electrode, Gas Test, HF/LIFT TIG and 2/4 LIFT TIG-HF TIG (High Frequency
TIG) selector switch’ to MMA function. In MMA mode, only three parameters (welding current,
hot start, arc force) can be adjusted.
MMA parameters can be adjusted as follows:
Turn on the welder, the welding current can be adjusted directly; If adjust the selection knob,
the welding current LED (L7) is twinkling; It means the welding current can be adjusted. If the
adjustment is completed, confirm the parameter by pressing the ‘selection knob’ or the system
will confirm the parameter automatically after 3 seconds.
Other parameters can be adjusted as follows:
Adjust the ‘Coated electrode, Gas Test, HF/LIFT TIG and 2/4 LIFT TIG-HF TIG (High Frequency
TIG) selector switch’ to MMA function. Press the ‘Welding Current and Parameter Control Knob.
Adjust knob’and select the arc force LED (L3 is on). Press the‘selection knob’again, the arc force
LED (L3) is twinkling; It means the arc force can be adjusted. If the adjustment is completed,
press knob’and confirm the parameter; Or the system will confirm the parameter automatically
after 3 seconds.
Hotstart parameter is adjusted by using same way. Adjust the ‘Coated electrode, Gas Test, HF/
LIFT TIG and 2/4 LIFT TIG-HF TIG (High Frequency TIG) selector switch’ to MMA function. Press
the ‘Welding Current and Parameter Control Knob. Adjust knob’and select the hotstart LED (L2
is on). Press the‘knob’again, the hotstart LED (L2) is twinkling; It means the hotstart be adjusted.
If the adjustment is completed, press the‘knob’and confirm the parameter; Or the system will
confirm the parameter automatically after 3 seconds.
8- Adjust the proper welding current to be found from the electrode data sheet according to the
electrode diameter, type and welding position with the “Welding Current and Parameter Control
Knob (3)”. In general, the welding current should be between the values indicated below.
However, adjusting your settings according to the values setout in the catalog of the welding
electrode manufacturer recommendations would be more appropriate.
This welding machine is designed for 2.50 and 3.25 mm diameter welding electrodes with
rutile and basic coating used for light welding operations.
Current range for rutile and basic electrodes:
Ø 2.5 mm : 70 - 100 A Ø 3.2 mm : 100 - 140 A Ø 4.0 mm : 140 - 200 A
9- Start welding observing the welding rules.
