FEMEROL MIG 250 MAX Review : Is It the Ultimate 7-in-1 Welding Machine? Introduction The FEMEROL MIG 250 MAX is a new entry in the multi-process welder market that is already gaining attention for its 7-in-1 versatility, Pulse MIG for aluminum, and large human-computer interaction LED display. Designed for both …

Welding Super Duplex Stainless Steel Super duplex stainless steels (SDSS) sit at the high-performance end of stainless metallurgy: they pair very high strength with excellent resistance to localized corrosion (pitting and crevice) in chloride-bearing environments. Because of that combination they’re widely used in aggressive process environments — think oil & …

How to Choose Shielding Gas for GMAW and FCAW Choosing the correct shielding gas is as important as selecting the right wire or welder settings. The gas directly controls arc behavior, heat input, penetration, spatter, and — ultimately — weld quality and mechanical properties. For GMAW (Gas Metal Arc Welding, …

Globular Transfer in MIG Welding Globular transfer is one of the classic metal-transfer modes encountered in Gas Metal Arc Welding (GMAW), commonly called MIG (Metal Inert Gas) welding when inert gases are used. It sits between short-circuiting transfer and spray transfer in both behavior and effects: the molten wire forms …

Welding Stainless to Carbon Steel Welding stainless steels to carbon (mild) steels is one of the most practical — yet metallurgically tricky — tasks a welder faces. The join is common in piping, heat exchangers, exhaust systems, and many retrofit repairs where corrosion resistance is needed only on one side …

Porosity vs. Blowholes — A Complete Practical Guide for Welders and Inspectors Porosity and blowholes are two of the most common gas-related discontinuities you’ll encounter in welding and casting. On the surface they can look similar—small pits, cavities, or irregular hollows in the weld—but their origins, shapes, consequences, and fixes …

MATRIXING MIG-205DP PRO Dual Pulse MIG Welder Review: Is It Worth Buying? Introduction The MATRIXING MIG-205DP PRO Dual Pulse MIG Welder is a feature-packed machine aimed at both serious hobbyists and small-shop professionals who need versatility without breaking the bank. With dual voltage support (110V/220V), multi-process capabilities (MIG, Flux-Core, Lift …

Welder Qualification Ranges Explained (WPS/PQR/WPQ): Thickness, Positions, Backing Suppose you’ve ever stood at the whiteboard trying to translate code tables into shop reality. In that case, you already know “welder qualification ranges” are the heart of getting people legally and safely onto the job. This guide unpacks how thickness, positions, …

VORITO VR-B12HD Auto Darkening Welding Helmet Introduction Welding helmets have come a long way from the old passive shades that required welders to nod their heads before striking an arc. Today’s auto-darkening welding helmets (ADWHs) are smarter, safer, and much more comfortable to use. Among them, the VORITO VR-B12HD Auto …

MIG Settings by Thickness (MIG Settings Chart & Tuning Guide) Getting MIG (GMAW) settings right begins with metal thickness. Thickness determines the transfer mode you can use, the wire size you should load, the gas you should choose, and—ultimately—the voltage and wire feed speed (WFS) that give sound fusion without …
