The power LED switch goes off. The status returns to normal when the power switch is turned on.
6.6 Setting Welding Conditions
This section explains how to set the welding conditions (welding mode or welding parameters).
6.6.1 Setting welding parameter
This section explains how to set the welding parameters (gas discharge time, welding current). Welding
parameters are set according to the welding sequence.
6.6.1.1 Welding sequence
The basic welding sequence is the process of PRE FLOW, MAIN CONDITION, and POST FLOW. To this
sequence, initial current and crater current 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:
⇒
The welding condition of the selected JOB No. is
deleted, and "End" is displayed on the right/left
digital meters.
Process Description
PRE FLOW It is the sequence to discharge gas before the welding starts.
INITIAL CURRENT It is the sequence to process the welding start.
UP-SLOPE This is the slope when the initial current is switched over to the main current.
WELDING (BASE)
CURRENT
It is the welding sequence.
DOWN-SLOPE This is the slope when the main current is switched over to the crater current.
CRATER CURRENT It is the sequence to process the crater part.
POST FLOW It is the sequence to discharge gas after the welding completes.
