Single purpose Hi-Lo Welding Gauge
Economy single purpose HI-LO welding gauge.
Features:
For checking the internal alignment of the fit-up quickly.
Easy operation determines rootweld spacing.
In metric measurements
Internal HI-LO Gauge four quick step check internal alignmen:
1. Unlock the retaining screw. Press the gauge legs beyond the barrel
2. Insert the legs (wires) into the root gap space of the two pieces of pipe to be fitted. Turn the gauge 90 degrees, being careful to apply a constant back pressure to the barrel.
3. Hold the gauge as square as possible with the fitting to obtain an accurate reading. Lock the retaining screw. Reverse the 90d turn and remove the gauge. You're now ready to read the increment opposite the red line.
4. When the red line aligns with the 1/32" increment you have a good internal alignment and fit-up. Misalignments can be determined.
