selector switch:
A - Current and Parameter Display Panel :
Shows adjusted current before starting the welding
procedures.
B - Gas Test :
Gaz test function
C - HF (High Frequency) ignition button
D- Puls Key
E - Overload/Temperature Warning Led :
These leds light up when the machine cannot provide
output current sue to overheating. This situation is encountered when the ambient temperature
rises above 40°C and the duty cycle (operating efficiency) of the machine is exceeded. Leave the
machine on and wait until it cools off. The machine will be ready for operation again when the
lamp goes off. It also lights up when over-voltage or over-current situations occur. At the same
time, display Err 001.
F - Trigger Selecting Key :
2T and 4T TIG s select button
G - AC/DC Selecting Key :
AC TIG and DC TIG select button
H - MMA Selection Button :
MMA select button, hotstart and arc force parameter select button
I - Welding Current and Parameter Control Knob :
Adjusts the output current and welding
parameters of the machine (welding amp. config).
MMA Welding
The following actions need to be done before starting the welding procedures:
1- 1- First determine the pole appropriate for the electrode used. This information can be found in the
data sheet of the electrode. Then connect the welding cables to the output according to the pole
required. For example; if DC (+) is to be used, connect the electrode cable to the (+) output of the
machine (4) and the grounding cable to the (–) output (3). Selecting a wrong connection may result
in unstable arc formation, too much splashing and the electrode sticking to the work piece.
Turn the connecter 1/4 clockwise after inserting in the plug with the guide pin on top. Make sure
that the connector is seated firmly in place without tightening too much. Otherwise, the loose
sockets may overheat and burn out during a prolonged period of use or high welding currents.
2- Attach the electrode to the electrode clamp.
