Welding 101
Rusty metal can sometimes be welded, but the condition of the steel and the level of corrosion determine whether it is safe. Learn when welding rusty metal is possible, how rust affects weld quality, and what preparation steps help create stronger welds.
Flux-cored arc welding (FCAW) is a wire welding process that uses a tubular, flux-filled electrode to create a weld with or without external shielding gas. This article explains how FCAW-S and FCAW-G work, why wire selection and welding settings matter, and when FCAW may be a better choice than MIG.
MMA welding, also known as stick welding, is a manual arc welding process that uses a flux-coated electrode to join metals without external shielding gas. Learn how MMA welding works, where it is used, and how it compares with other welding processes.
A NEMA 6-50 plug is a common power connector for 240V welders, but a safe setup also depends on the correct breaker, wire size, outlet, and grounding. This guide explains how a NEMA 6-50 plug works, how to wire it safely, and what to check before powering up your welder.
Can you weld in the rain? Wet conditions can increase the risk of electric shock, equipment damage, and poor weld quality. This guide explains when outdoor welding may be possible and the best practices for staying safe.
