Wire guide is necessar for customers using TIG filler welding.
Wire guides are available for steel, stainless steel and aluminum
【L7724A：For steel • SUS／20 degrees or 30 degrees of filler inserting angle】
【L7725A：For aluminum／25 degrees or 30 degrees of filler inserting angle】
Bracket assembl (L7640B) is used in common regardless of filler inserting angle and wire diameter, but the part
number of the wire guide assembl is different depending on the wire diameter and filler inserting angle.
See Table 5.1 and Table 5.2 and select the wire guide assembl suitable for specifications of the customer.
For details, see Parts List in Chapter 13. For outline drawing, see Fig. 5.1.

○ EX manipulator
Check if the message “l 10002-0100 Mechanism shock sensor” appears in Teach mode b
pushing in the torch tip with our hand.
The message will disappear b unhanding the torch. If the message does not appear, the shock
sensor ma be broken. Check the shock sensor again.

The shock sensor unit is to minimize deformation of the welding torch
likel caused b the collision among welding torch, workpiece or jigs,
and damage inflicted on the robot bod , workpiece or jigs. Therefore,
reproducibilit on the torch tip cannot be guaranteed if once the shock
sensor has been operated. (If once the shock sensor has operated, be
sure to check the aiming point of torch again with the torch gauge.)
