Welding Jig

Electric Welding Jig

welding jigThe electric welding jig is engineered for use in fabrication shops or on the job site. Its unique clamping system acts both to move the pipe and fittings on and off the welding iron and to hold the pipe and fittings perfectly straight as the fusion connection cools.

  1. Assemble the welding jig by following the instructions included in its carrying case. Improper or abusive assembly can cause the sliding clamps to jam. Ensure that all moving and sliding parts are properly lubricated.
  2. Prepare pipe, fittings, and welding iron as directed in parts A and B. Use the blue marking template included with the electric welding jig rather than the green one included with the welding iron.
  3. Set the clamps to the proper positions for the size of pipe you will be using and lock them into place. Use the smaller knob located on the side of the clamp to adjust for tightness.
  4. Secure the jig to the pipe-end being fused. It is important to secure the pipe at such a depth that it can be properly inserted into the welding tool without the clamp coming into direct contact with the welding head. This is generally ½’ to 1” beyond the prescribed welding depth.
  5. Secure the fitting tightly against the stop.
  6. Use the forward action of the jig to gently push the pipe and fitting onto the welding iron. If the jig’s transmission begins clicking, stop and relax pressure slightly. The larger sizes of pipe and fittings often needtime to heat up before they will go onto the welding tools completely. It is best to apply constant low pressure.
  7. Once the pipe and fittings have reached the proper welding depths, relax pressure slightly and begin the heating time.
  8. Once the heating time is complete, use the reverse action of the jig to pull the pipe and fitting free of the welding iron.
  9. Use the forward action of the jig to push the pipe and fitting together until the double ring of PP-R forms. Leave clamps in place for the prescribed weld time. If the joint is being subjected to undue pressure, the clamps should be left in place for the cooling phase as well.
