A practical comparison of control, speed, preparation and working conditions.
Welding aluminium: why preparation changes everything
Oxide removal, alloy identification and wire feeding explained before you choose a process.
Pulsed MIG: what the extra control actually does
Understand peak and background current, and where pulse can make a useful difference.
MIG welding spatter: investigate what changed
Learn how to record a sudden increase in MIG spatter, check consumable identity and separate equipment, distance and arc-control questions.
TIG end craters: plan the finish before stopping the arc
Understand why a TIG weld can end in a hollow, how current and filler coordination matter, and when a suspect termination needs assessment.
Flux-cored wire polarity: read the wire, not the process
Learn what DCEP and DCEN mean, why two flux-cored wires can require opposite polarity, and what to verify before changing a spool.
TIG post-flow: why the gas continues after the arc
Learn what TIG post-flow protects, why timer ranges differ by machine and how to check your setup without guessing a universal setting.
