Welding supplies

Need electrodes, flux or solder? We can help. Just tell us what you are looking for.


In arc welding an electrode is used to conduct current through a workpiece to fuse two pieces together. Depending upon the process, the electrode is either consumable, in the case of gas metal arc welding or shielded metal arc welding, or non-consumable, such as in gas tungsten arc welding. For a direct current system the weld rod or stick may be a cathode for a filling type weld or an anode for other welding processes. For an alternating current arc welder the welding electrode would not be considered an anode or cathode.


The term flux means to clean. Not all welding processes use a flux. Stick welding electrodes contain fluxing agents. MIG hard wire doesn't but flux-cored MIG wire does. TIG does not as the rods are bare. Most brazing applications require flux. Gas welding usually doesn't except for certain metals.

Solder joins two pieces of metal together. The solder, typically a lead/tin alloy, melts at a lower temperature than the base metal, or pieces needing to be joined, and when the base metal is clean and appropriately treated with flux, the molten solder will adhere to the metal pieces, cool, solidify and hold them together. This is the weakest of the three processes. Soldering is used extensively for electrical connections, joining sections of copper pipe in plumbing, for fabricating copper flashings around chimneys, and for such things as filler for the joints between the roof of a car to where it meets the rear column of the rear quarter panel. Silver Solder is a specialized solder alloy which is many times stronger than ordinary tin/lead alloy solders. I used Silver Solder to join the ends of band saw blades - I make my own, buy the band saw blade stock in long lengths. Depending on the job at hand, you would either use an electric soldering iron for most electrical work, or a propane torch for plumbing work. Auto body shops that do body solder work typically use a specialized acetylene torch.
