Kemppi AX MIG Welder Operating Manual

AX MIG WelderOperating manual - ENThe free trial registration includes both the WeldEye Welding Procedures and WeldEye ArcVision modules.3.3.13 Through Arc Seam Tracking (TAST)TAST is used for providing precise welds depending on specific weld characteristics or in setups where the position ofthe work piece varies during repetitive tasks.TAST can be used with the following welding features and processes:• 1-MIG• Pulse• WiseFusion• WiseSteel• WisePenetration+• MAX SpeedEnsure that the robot supports the use of TAST.TAST is configured in the robot and its use varies between robot brands. For more information, refer to the robotmanufacturer's instructions.The TAST signal is a reference value based on the welding current that is affected by the arc length and the filler wirestick-out length.TAST requires weaving for horizontal and vertical seam tracking. The figures below show that at the center of the weldseam, the current is at a minimum. As the gun reaches the edge of its weave cycle, the current peaks.Gun weaving during seam tracking TAST signal wave form1. Short stick-out length2. Long stick-out length3. Short stick-out lengthx = Timey = TAST signal valueThe power source sends the TAST signal as a reference value to the robot that uses the value to keep the stick-outlength stable in relation to the weld seam, and make necessary corrections to the welding path.© Kemppi 142 1921900 / 2318
