Thread Tools Show Printable Version. For safety, always make sure the power is off before performing this test. About all the pipeliners that I see around here use spools and always have.

Using Steel Bars or Reinforcing Rods In some welding applications, a steel bar or a steel reinforcing rod may be used as a work lead connection or between two or more weldments. Welding lead do's n don'ts I am setting up my welding rig my new job and most of the guys have welding lead reel spools on thier trucks. An improvement on sliding brushes, preloaded, tapered roller bearings are excellent for rotating grounds. Also, keep in mind that aluminum is poorly suited for this purpose, why do i as it quickly forms an oxide that is poor conductor of welding current.

When in doubt, refer to the equipment's operation manual or call a qualified electrician.

Remember that the work lead cables or cables should be neatly organized, not strung about haphazardly. The more coils and the more current you have flowing through those coils makes for stronger effects. When grounding is through a sliding shoe, two or more shoes should always be used. Also, dating a powerful woman this is good time to inspect the electrical cables connected to the welding power source and determine if the cables can be safely used or needs to repaired or replaced.

Attaching the Work Lead to the Workpiece A high production automotive part may benefit from more than one connection. The arc itself is a very complex phenomenon. If any of these conditions occur, inspect your work lead connections immediately. Cleaning the area of contact with sandpaper or a wire brush before making the connection is good practice. The experienced welder knows that good work lead connections are essential for good welds and should not be overlooked.

As he welded the loops would move and quiver, and it was obvious they were moving due to magnetic effects of the current they were carrying. If I'm working on the back of the truck I have a second lead right off the welder to plug the stinger into. The work lead clamp is bolted to the lug at the end of the work lead cable and has brass or copper jaws to ensure good electrical contact to the workpiece. This should be performed immediately after an hour or more of welding after the power source is disconnected. To do this, a smooth flow of electricity needs to complete the electrical circuit, hence the need for good electrical connections.

If the entire cable is hot to touch, nude dating service it is probably undersized for the welding current being used. Automatic circumferential welds usually use a work lead connection of brushes or rotating or sliding shoes with an electrically conductive lubricant. It makes them easier to handle and keeps them from getting tangled. Safety The hazard of electrical shock is one of the most serious and immediate risks facing personnel working in the welding area.

  1. To assure trouble-free performance, the contact area of the bearing should be sufficient to carry the current capacity of the welding cable used in the installation.
  2. In addition, poor connections reduce the voltage at the welding arc.
  3. For everyone's safety, always keep your cables in good condition.
  4. Automatic welding installations commonly use a permanent stationary connection.

To be effective, the work lead must make good electrical contact with the workpiece. Be careful not to allow the weldingcurrent to flow through sensitive electronic components. Testing the Circuit A simple way to test the soundness of the circuit is to run a hand over the length of the cable from the power source to the electrode. When using steel bars, minnesota dating care must be taken to assure that the bar has adequate cross-sectional area to match the copper welding cable in total electrical conductivity.

Regardless of how the work lead connection is made, it should be a secure positive connection, properly placed to minimize any welding interference or arc blow. In arc welding, an arc is established from the electrode to the workpiece. The work lead connection may vary with the welding process, amperage, or application.

Portable Cord

  • Locked up in the drawer, I don't worry about them being stolen and they stay out of the sun and rain too.
  • This means that the area of contact must be free from any scale, rust, oil, grease, oxides, or dirt that may act as points of insulation.
  • Any heating of the lead is coming directly from the power generated by the welder and is coming from the burning of fuel and is power not getting to the arc.
  • The work lead clamp may be attached directly to the workpiece or to the fixture holding the workpiece.
  • Since the conductivity of copper is almost seven times that of mild steel, the cross-sectional area of the steel bar should be at least seven times the cross section of the welding cable conductor.

Be careful not to allow the welding current to flow through sensitive electronic components. Troubleshooting Poor work lead connections may arc and weld the connection to the workpiece. This article will explain some of the ways to achieve a good work lead connection.
