9 Arc Welding Application9.3 Function Outlines9-12149235-1CDRE-CSO-A0319.3.8 Slope Up/Down FunctionThe slope up/down function is used during welding to gradually change the welding condition. Thisfunction is extremely effective in conducting heat for such operations on workpieces such as the oneshown below.During the welding of a workpiece as shown below, especially during the period before the end ofwelding, the tearing and dropping of metal can occur quite frequently due to heat conduction.However, even in this example, if the welding condition is gradually decreased before the end ofwelding, tearing and dropping of metal can be prevented.Reference JobNOPMOVL V=500ARCON AC=210 AVP=100MOVC V=80MOVC V=80MOVC V=80MOVC V=80ARCCTE AC=180 AVP=100 DIS=20.0MOVC V=80ARCOF AC=160 AVP=80 T=0.30ENDMoves to welding start point P1.Arc starts.Moves to taught point Pn-1.Gradually decreases the current from the point 20mmshort of the welding end point.Moves to welding end point Pn.Arc ends.Welding start point (P1) and weldingend point (Pn) must be the same.P1 P2 Pn-1 PnCurrent Main conditionWelding conditiongradually decreases.(Slope Up/Down Func.)End conditionManipulatorstop (0.3s)20mm210180160355 of 493
