The MM-410A handheld resistance weld checker is the latest in stand-alone weld checker technology, ideal for setup, production monitoring, and troubleshooting. The MM-410A enables operators to monitor and manage key welding variables that result in changes in weld heat such as current, voltage, time, and force. The compact, handheld unit supports a wide range of resistance welding technologies including AC, DC inverter, AC inverter, transistor, and capacitve discharge. Its 5.7″ color touch panel display offers a simple user interface.

Features

• AC, DC inverter, AC inverter, transistor, and capacitive discharge
• Measures current, voltage, time and conduction angle (Force measuring with optional Current/Force Sensor – MA770A / MA-771A)
• Improved accuracy through ISO 17657 compliant toroidal coil
• Easy setup via 5.7″ color touch panel
• Seam welding mode – Monitor AC current and voltage or DC voltage for up to 5 minutes
• ISO 17657 – compliant measurement for current – Requires ISO-compliant toroidal coil
• Data storage via on-board flash drive
• Ethernet (TCP/IP), and USB communication
• Multi-language support: English, Spanish, Japanese, Chinese, Korean, German, and French

Common Applications:

Process Development

• Correlate waveform and numeric data with process results
• Provides detailed weld data for process optimization and validation

Production Environment

• Reduces scrap – Detects drifts in the weld process and alerts operators before process failure
• Reduces frequency of destructive testing – Welds that pass the set parameter limits indicates the process is in control
• Independent monitoring of welding power supply – Detects drifts in welding power supply calibration
