Niigata Seiki Welding Gauges 
Exclusive use for undercut measurement 
High Quality 
Made in Japan 
 

Exclusive use for undercut measurement

• Stainless steel(SUS420J2)
• Easy and accurate to measure depth and length of undercut
• Dial gauge type performs more precise measurement
• Three point support for stable measurement

Zero Adjustment

Recommended to be performed on a flat surface such as a surface plate.

1. Loosen GAUGE PROBE RETAINER SCREW using hex key.
2. Place Welding Gauge on surface insuring all three points of MEASUREMENT BASE are making contact (2x ADJ, 1x FIXED) and push on SPINDLE shaft. When 1mm POINTER indicates 4.00mm, tighten GAUGE PROBE RETAINER SCREW. (Insure that probe tip is in contact with the surface plate)

Measurement

1. Place the gauge on a flat surface and rotate BEZEL to indicate 0.01mm. (Figure 1)
2. Place PROBE tip on weld undercut point to be measured. (Figure 2)
3. Undercut value is obtained by subtracting Dial Gauge reading from 4.00mm.

• Measurement range: 0~4.00mm
• Minimum reading:0.01mm
• Accuracy:±0.04mm
• Width of measurement base : nearly equal 23mm
