TIG Torch Materials– What’s the Difference?

Air Cooled TIG Torches at Arc-Zone.comA lot of folks wonder what the difference between inexpensive import TIG Torches you see being sold at a lot of online welding suppliers, and the quality name brand– and yes, more expensive TIG torches such as the ones carried by distributors like Arc-Zone.com.

One of the biggest differences between brand-name and no-name torches is the materials used in manufacturing…

There is tellurium copper, which is very basic plumbing type copper and then there is leaded nickel copper which is a high conductive, high tensile strength copper alloy. This is important for two reasons, one it’s a better conductor, and two it is more durable, the TIG torch body threads last longer, collets don’t buckle and twist etc.

Silicone Rubber
Weldcraft changed the rules when they introduced the Silicone rubber molded TIG torch. Prior to that all torches were molded in a hard plastic material. Difficult to hold, impossible to bend and very susceptible to arcing out. You would think that silicone rubbers are all the same, but again there is a big difference in the material quality, and how much heat it takes before it begins to breakdown, and how well it is bonded to the copper TIG torch body. Materials and preparation are key here and come back to the basics of production standards
