6.6.2
Setting welding parameter
This section explains how to set the welding parameter (gas discharge time, welding current/voltage).
The welding parameters are set according to the welding sequence.
6.6.2.1
Welding sequence
The basic welding sequence is the process of PRE FLOW, MAIN CONDITION, and POST FLOW. To this
sequence, initial condition and crater condition can be added depending on the crater setting. The
welding parameters such as gas discharge time, welding current and voltage should be set to this
sequence.
Each sequence process has the following description:
Process
Description
PRE FLOW
It is the sequence to discharge gas before the welding starts.
INITIAL CONDITION
The welding is carried out in this sequence during when the torch switch is ON.
MAIN CONDITION
It is the welding sequence.
CRATER -FILL
CONDITION
It is the sequence processing the crater part.
POST FLOW
It is the sequence to discharge gas after the welding completes.
