The Back Purge Wand attachment allows for the welding of ends on features, such as ferrules and field applications. In these situations, traditional flow-through is not available or can waste excessive amounts of gas mixture. The attachment utilizes any size purge plug with a spring-loaded end cap that is machined to fit the I.D. of your workpiece allowing you to expel oxygen in reverse.
Avoid purging the whole line for one weld. This attachment can get it done with only purging the final 6″ before the weld. This piece pays for itself in gas savings alone. The Back Purge wand can be bought individually here or is included in our Purge Plug Kit – Hard Case.
Range: 1.5″ to 4″ sanitary tube
