Portable WeldView® Monitor

Resistance Welding Diagnostics In A Suitcase

The Portable WeldView® Monitor is designed to monitor any resistance welding application: 50/60 Hz; AC/DC single and three phase; capacitive discharge; inverter power supply; spot, seam, projection, flash/butt welders. NIST-traceable electronics calibration is easily performed with a voltmeter. Current calibration requires no hardware adjustment.

BENEFITS

• Benchmark the electrical and mechanical performance of every welding machine.
• Verify the set-up and performance of every welding job.
• Instantly measure the consistency of every weld without performing destructive tests that waste material and slow down production.
• Determine the optimum production heat and time settings without performing multiple destructive tests.
• Recognize when a shift in the welding process has occurred that requires corrective action.
• Rapidly pinpoint the source of a process shift so that the problem can be corrected without incurring unnecessary downtime.

FEATURES

• Monitors half-cycle by half-cycle secondary current and voltage, electrode force, work-piece thickness and dis-placement, conductance, power and conduction angle.
• Upper and lower limits can be established easily for every half-cycle of each monitored parameter.
• Notification of out-of-limits condition is made via the graphic display and via a fault signal output.
• Weld data with upper and lower limits are displayed immediately after each weld.
• Weld data are stored digitally in the data archive for SPC purposes or future proof of weld quality. Data can be converted for use in third party spreadsheet applications.
• Acquisition time selectable from 10 microseconds to 10 minutes. Current waveform for machine diagnostics.
