c. STEP MODE
This is the mode to check the force operation of the electro pneumatic proportional valve.
In this mode, the force operation can be checked without flowing the welding current. The
sequence proceeds to the next in order of SQD, SQZ, WE1, CO/WE2, CO2/WE3, and HOLD
by pressing the ENTER key or input the STEP MODE signal.
Do not move the cursor from STEP MODE during this mode. Settings cannot be changed.
Valid only when FORCE CONTROL MODE on the PRESSURE REGULATOR screen is not
0.
Turning on the step operation mode
Set STEP MODE to ON.
SQD
Closes the 1ST signal. When the 1ST signal is input, the force set in SQD is output to the electro
pneumatic proportional valve (ANALOG OUT), and SQD and CONTINUE blink.
The measured value input in the force input (ANALOG IN) is displayed at the monitor of SQD.
SQZ
The sequence proceeds from SQD to SQZ by press the ENTER key or input STEP MODE
signal. The force set in SQZ is output to the electro pneumatic proportional valve (ANALOG
OUT), and SQZ and CONTINUE blink. The measured value input in the force input (ANALOG
IN) is displayed at the monitor of SQZ.
WE1
The sequence proceeds from SQZ to WE1 by pressing the ENTER key or input the STEP MODE
signal. The force set in WE1 is output to the electro pneumatic proportional valve (ANALOG
OUT), and WE1 and CONTINUE blink. The measured value input in the force input (ANALOG
IN) is displayed at the monitor of WE1.
CO1/WE2
The sequence proceeds from WE1 to CO1/WE2 by pressing the ENTER key or input the STEP
MODE signal. The force set in CO1/WE2 is output to the electro pneumatic proportional valve
