Look no further than Weldclass Platinum GL-11 ® – rated by thousands of welders as Australia’s best gasless wire! Looking for a smooth-running, hassle-free Gasless Wire…? Connect this to the Negative (-) terminal. Usually there will be a short lead that can be connected to either a positive or negative terminal. The polarity connections for the torch are commonly found either on the inside of the welder (near the wire drive system as shown below) or on the front of the welder. (This is the opposite to standard MIG welding with gas, which is torch/wire positive and earth negative).Ĭonnect the earth lead to the positive (+) terminal on the front of your welder. When running gasless welding wire – connect the Earth to positive and Torch to negative, otherwise known as "DC electrode negative", or "straight polarity". Can’t remember which terminals the torch & earth clamp go to? Wire not running properly? Poor penetration?ĭon’t stress – even the most experienced welders can get it wrong! If your gasless welding wire is not running properly, or has poor penetration, then there’s a good chance that the polarity is wrong.
