Loosen the bolts A and B to the wire from the torch so that the wire end is positioned at the center of the centering gauge. Then fasten the bolts A and B tight. If the centering of the welding torch is neglected, trajectory of the torch tip when the wrist part of the torch is rotated does not show exact round, and displacement of the aiming point may be the result.Read the instruction manual of torch holder (YA-1AH011T03) together with this manual.Hex. bolt ,l4~12bottom coverHex. bolt,l4~8Centering gaugeArc start pointC: Torch positionadjustment holderAB
