AMADA Electrode Force Gauges

What is an electrode force gauge?

An electrode force gauge is a measuring instrument used to determine the mechanical force applied between the electrodes of a resistance welding machine. It is commonly used when establishing weld schedules, checking machine setup, troubleshooting weld quality, and performing preventive maintenance.

What is electrode force in resistance welding?

Electrode force is the mechanical force applied by the welding electrodes to hold the workpieces together during the welding cycle. Along with welding current and weld time, electrode force is an important resistance welding process variable.

Why should electrode force be measured?

Measuring electrode force verifies that the actual force at the electrodes matches the value required by the weld schedule. This can help maintain process consistency and identify changes in the welding machine’s pneumatic, mechanical, or electrode systems.

What AMADA electrode force gauge sizes are available?

AMADA electrode force gauges are available with capacities of 20 lbs, 100 lbs, 200 lbs, 10 kg, and 100 kg, depending on the model.

How accurate are AMADA electrode force gauges?

The AMADA electrode force gauges listed here have an accuracy of ±2% of full scale.

Are calibrated AMADA electrode force gauges available?

Yes. Calibration Certificate models are also available for applications that require documented calibration.

Where can I buy an AMADA electrode force gauge?

Weld Systems Integrators supplies AMADA electrode force gauges and other resistance welding measurement and process-control equipment. Contact WSI for pricing, availability, and assistance selecting the correct gauge for your welding application.

AMADA force gauges can be useful for resistance welding equipment used in applications including:

• Spot welding
• Projection welding
• Micro resistance welding
• Press-type welding R
• ocker-arm spot welding
• Bench welding
• Welding head setup and calibration
• Weld schedule development
• Preventive maintenance
• Resistance welding troubleshooting

For the Amada/Miyachi FG series, internal system adjustment and official calibration must be performed by the manufacturer or an accredited metrology lab. These units lack user-accessible dials or software adjustments for field calibration.

• Factory-Level Calibration: Standard calibration requires proprietary software communication and data logging via the unit’s rear serial connection interface. If your force gauge drifts out of tolerance, it must be routed directly back to Amada Weld Tech Service or an authorized stocking distributor like Weld Systems Integrators (WSI).
• Third-Party Certified Verification: If your quality program requires independent ISO/IEC 17025 or ANSI/NCSL Z540-1 compliance with full tracking data, certified labs like Micro Precision Calibration manage full-spectrum testing profiles specifically for models like the Miyachi FG100.
