2.19. ARC_COND

 

Description	The ARC_COND statement is a command to set the current, voltage, speed, weaving width, and weaving frequency for arc welding. The user can also change the condition, linearly ranging from the current ARC_COND condition to the next ARC_COND condition. In other words, the interpolation conditions will be applied in consideration of the left direction distance / right direction distance (gap), and the welding speed and weaving width will be automatically calculated based on the gap. The parameters to be set by this command can be individually designated and set by reading the desired welding condition database and designating the WDB number.
Grammar	•  ARC_COND <Welding condition change method>, <Welding speed>, <Left direction distance>, <Right direction distance>, <Weaving frequency>, <Current>, <Voltage> •  ARC_COND <Welding condition change method>, WDB#=<Welding condition database>
Parameter	Welding condition change method	Work program number where the station calibration is being taught	1 ~ 9999
	Welding speed	Designates the robot movement speed in the welding section; The speed in the MOVE statement ignored	0.6~1000 cm/min
	Left direction distance / right direction distance	Sets the amplitude of the left/right direction for the weaving operation	0.0~50.0 mm
	Weaving frequency	Sets the weaving frequency	0.0~10.0 Hz
	Current	Sets the welding current for the welding section	1~1000 A(%, m/min)
	Voltage	Sets the welding voltage (compensation) for the welding section	-200~200 V(%)
	Welding condition database	Sets the welding condition database number to be used in the welding section	1~1000
Example of usage	•    ARC_COND L, 30, 4, 4, 3, 400, 28 •    ARC_COND L, WDB#=1 •    Interpolation condition editing window If four points are set as the interpolation conditions as above, it will be possible to change the weaving width and welding speed by performing linear interpolating variably according to the sensed gap, instead of the set left and right weaving widths. In the figure, the circles represent the welding speed and width interpolated for the reference conditions expressed in dotted lines with regard to the current gap.
