SPATZMulti04 Weld Checker & Monitor for RSW

The SPATZMulti04 is an innovative, manufacturer-independent weld checker for resistance spot welding (RSW) applications. It enables the simultaneous real time recording, analysis and monitoring of all important process variables, such as welding current, electrode force and voltage. It is the first weld monitor which is capable monitoring all 4 weld parameters within just one device. Not only within process development but also during process control, our device helps to obtain an easy way to setup cost effective manufacturing systems.

SPATZMulti04 Accessories

Force sensors

In order to use the SPATZMulti04 as weld force meter, it can be equipped with an external sensor. The electrode force is measured with a force sensor which is integrated in a measurement head. Three different sizes allow a combined force and voltage measurement in welding guns as well as in miniature welding heads. The handle may be taken off for stationary installation. For the SK-100 inserts are available for use with flat electrodes (e.g. for projection welding applications).

Current sensors

Operating as weld current meter, it is mandatory to choose the right sensor. The measurement is accomplished with isolated toroidal coils. There are two different versions available.

current sensor 1
SI-15B (Flexible coil with lock)
For easy handling, this loop has a built-in fastener and is encompassed around a conductor element of the weld current.

Measuring range: 100 A - 200 kA
Current: AC / DC
Sensitivity: 150 mV / kA at 50 Hz
Diameter: 170 mm (6.7") inner &
200 mm (7.9") outer
Cable length: 2 m (78.7")
current sensor 2
SI-15F (Rigid coil with electrode insets)
This current sensor is placed on the electrode. There are insets for three different electrode diameters available.

Measuring range: 100 A - 200 kA
Current: AC / DC
Sensitivity: 150 mV / kA at 50 Hz
Diameter: 35 mm (1.38") inner &
80 mm (3.15") outer
Cable length: 3 m (118.1")
 

Voltage sensor

The measurement of electrode voltage is accomplished with a 2-wire sensor cable. The highly flexible ends of the cable can be attached using the various types of adapters.

voltage sensor 1
SU-02
Sensor cable: Highly flexible
Cable length: 2 m (78.7")
 
 

I/O-Cable

I/O-Cable to connect the SPATZMulti04 e.g. to a PLC.
