Single Purpose HI-LO Welding Gauge

Available in Standard or Metric

Internal HI-LO Gauge

Single Purpose HI-LO

4 quick steps check internal alignment

  • Unlock the retaining screw. Press the gauge legs beyond the barrel.
  • Insert the legs (wires) into the root gap space or the two pieces of pipe to be fitted. Turn the gauge 90┬░, being careful to apply a constant back pressure to the barrel.
  • Hold the gauge as square as possible with the fitting to obtain an accurate reading. Lock the retaining screw. Reverse the 90┬░ turn and remove the gauge. You are now ready to read the increment opposite the red line.
  • When the red line aligns with the 1/32 increment line you have a good internal alignment and fit-up. Misalignment can be determined from the zero line by increment markings of 1/16 inch

Root weld Spacing Gauge

Single Purpose HI-LO

Easy operation determines rootweld spacing.

  • Unlock the retaining screw and insert the gauge interior alignment stops between the two pieces of pipe to be fitted.
  • Insert the leg with the longer taper into the root gap until it makes contact with both sides of the gap.
  • Re-lock the retaining screw, remove the gauge and read it.
  • The scale is calibrated in fractional dimensions from 1/32 to 3/16 in 1/16 inch increments. The read-out you receive represents the amount of rootweld gap.
