Spot Welders, Spot Welder Repair, Resistance Welding Supplies

The Kranitz Corporation offers new and used spot welders, welding controls, electrodes, spare welding parts, and welding fixtures.

We are the leaders in the refurbishing of your spot welding equipment and updating your welding controls. When you send in your spot welder, we do the following:

  • disassemble the machine
  • clean and paint the frame and castings
  • silverplate all electrical connections
  • replace all worn airline components
  • replace all air and water hoses
  • install and test the control of your choice
  • reassemble and test the machine

We carry a selection of new welding equipment and can supply you with spot, spot/projection, buttwelders, hanging guns, and rocker arms.  We stock an Entron control in our shop ensure we get your machine up and running quickly.  We can also install, on our floor, welding controls from major manufacturers such as Entron, Medar, Robotron, Unitrol, and WTC.  

We have in stock a large number of spare parts (electrodes, shunts, transformers, welding cables, valves, and airline components).  We also have loaner boards, panels and parts for controls, including some older Square D and Peer.         

We handle Mallory, Tuffaloy, and Pacific electrodes in any quantity needed. Typical delivery is within a few days. Special electrodes that we build or order take a little longer. For prices or to place an order just email or give us a call.  We are able to take either VISA or Mastercard.

Another area we are renown for is our special machinery. We can design and fabricate welding equipment to simplify your welding applications. We have supplied A-frame style, pass through,  multi-gun, and turntable machines.  These can be either manually operated or computer controlled.  

We also buy and sell used welding equipment. We offer machines that we have remanufactured and are in excellent condition. New or used controls can be installed on these machines to provide you with a low cost alternative to the price of a new machine.
