Step 5:Stickout length
The stick out refers to the distance between the wire and the contact tip while welding. It is important to keep the stick out short to achieve the best welding results.
A longer stick out increases the resistance in the circuit, leading to a drop in amperage. Additionally, when the torch moves farther from the joint, the gas coverage becomes less effective. Therefore, it is recommended to maintain a short stick out, typically around 1 cm.
After each weld, it is a good practice to cut the wire back to the appropriate length for optimal stick out and ensure that the end of the wire remains clean. If the wire end is left in a balled condition, it may result in a cold start with insufficient penetration. The excess blob of wire needs to burn off before proper welding can occur.
By maintaining the correct stick out length and keeping the wire end clean, you can achieve better control and more consistent welds, enhancing the overall welding performance.
Step 6: Keep Your Consumables Clean
It is crucial to maintain clean consumables during the welding process. Consumables include items such as contact tips, nozzles, and diffusers.
Dirt, debris, and spatter can accumulate on these components, which can lead to issues like poor weld quality, inconsistent arc, and blockage of gas flow. To avoid these problems, regularly inspect and clean your consumables.
Use a wire brush or a dedicated cleaning tool to remove any built-up spatter or debris from the contact tip, nozzle, and diffuser. Ensure that the gas ports in the nozzle are clear and unobstructed.
By keeping your consumables clean, you ensure optimal performance, maintain consistent weld quality, and extend the lifespan of these components. Regular cleaning and maintenance of consumables are essential practices for successful MIG welding.
