WELDING TORCH WITH A FIRST CONTACT TIP TO PREHEAT WELDING WIRE AND A SECOND CONTACT TIP

摘要

The present application relates to welding torches (1500). A welding torch includes a welding assembly comprising: a first contact tip configured to conduct welding current to a consumable electrode; and a second contact tip configured to conduct preheating current to the consumable electrode; a neck having a bend, the neck configured to hold the welding assembly and to deliver the consumable electrode to the welding assembly; a torch body configured to hold the neck opposite the welding assembly; and a torch mounting assembly; wherein the welding assembly, the neck, the bend, the torch body, and the torch mounting assembly are dimensioned such that the welding torch (1500) provides a same tool center point distance, a same bend angle, and a same approach angle when used to replace a second welding torch (1500) having a single contact tip.
