MA-520B/521B/522B 1. Special Precautions (1) Safety Precautions Before using, read "Safety Precautions" CAUTION carefully to understand the correct ！ method of use. These precautions are shown for Denotes operations and practices that ■ safe use of our products and for... - Page 4 MA-520B/521B/522B WARNING ！ Do not put your hands between the electrodes. When welding, keep your fingers and hands away from the electrodes. Do not touch any welded part or electrodes during welding and just after welding finished. The welded part of a workpiece, electrodes and electrode holder are very hot.
- Page 5 MA-520B/521B/522B CAUTION ！ Use ear protectors. Loud noises can damage hearing. Protective gear must be worn. Put on protective gear such as protective gloves, long-sleeve jacket, leather apron, etc. Surface flash and expulsion can burn the skin if they touch the skin.

MA-520B/521B/522B 2. Features MA-520B/521B/522B is an electrode force sensor for resistance welding machine. By connecting this sensor to the special weld force gauge sold separately (MM-400A), the weld force over a wide range can be measured easily. This sensor can be carried easily, since it is both small and light. -

Page 9: Measurement Method
MA-520B/521B/522B 5. Measurement Method Before measuring the weld force, be sure to turn off the welding machine and confirm that the power is not applied. If the welding power is applied while the weld force is measured, the sensor may be broken. - Page 10 In this chapter, we will explain about the optional jig for simultaneous force application and welding (A-04860-001). This jig can be used for MA-520B/521B only. (This cannot be mounted to MA-522B.) (1) Introduction This is a jig for measuring the weld force of the welding head which has two electrodes such as parallel gap welding and series welding.
- Page 11 MA-520B/521B/522B (3) Usage • Set the electrodes at the center as much as possible. • Put the electrodes on the weld force sensor as perpendicularly as possible. Remove oxide and any extraneous substances from the surface of electrodes to smoothen the surface, and then make a measurement.
