Example:
In the setting examples of F29: "5" ; F30: "0" ; F31: "5" ; and F32: "0" , the following diagram is available:
• Before 100 ms of the torch switch ON (start signal "ON"), set the welding condition to "5" for F29 to F32 to
read out the welding JOB No.
• To switch plural signals at the same time, carry out the operation within 40 ms.
• From 40 ms before the torch switch OFF (start signal "OFF") to 100 ms after it, do not change the setting of
"5".
6.7.2.22 F33: Inhibition ratio display for [Squeeze] detection
Any shift in detecting [Squeeze] leads to spatter generation. This function enables to check the
inhabitation ratio (%) of [Squeeze] detection from the welding start to the welding completion.
• Selecting F33 after the welding completion displays the inhabitation ratio on the right digital meter.
• Welding operation is available with F33 selected.
• When the welding is unstable, the inhabitation ratio may accordingly become unstable. When this
happens, review the welding condition first.
• Even when the welding is stable, adjust the detection sensitivity of [Squeeze] using the internal functions
F36 / F37 (Spatter adjustment) when the inhabitation ratio is 70% or less. (
