INTRODUCTION
SpotWelding Manual for Medar 1-6 MOTO MAN
1.3.5 Water Cooling System
The water cooling system circulates water through both the spot weld controller
and the weld gun. It is important that the water temperature not exceed 86° F, as
inadequate cooling could damage the servo weld gun and transformer.
The Medar board supports thermal overload sensors from the transformer and
Medar SCR. External flow sensors may be integrated with the XRC as an interlock
for welding.
1.3.6 Tip Dresser (Optional)
The optional tip dresser is used to remove weld flash, oil, grease, or any other
deposit from the weld tip that may affect the gun’s ability to function properly.
The tip dresser also grinds the contact tip back to its original shape. The servo gun
can vary pressure during tip dress for cut and polish.
1.3.7 Work Cell
In addition to the items above, a complete system typically includes certain work
cell components. These components are not specifically part of the spot welding
package, but are related items that are supplied separately. Some of these items
include light curtains, interlocks, arc screens, fencing, and positioners. The
number and type of components required depend on the specific application.
1.4 Equipment and Component Specifications
Specifications for the typical spot welding system and its components are listed in
Table 1-1. Additional information is provided in the various vendor manuals
