Why replaceable lenses matter A welding helmet’s cover lenses are the clear, sacrificial pieces that protect the auto-darkening filter (ADF) from spatter, scratches, smoke residue and cleaning damage. Most helmets…
Why grinding between weld passes matters Slag, spatter and sharp edges can hide defects or interfere with the next pass. Grinding them off is part of the weld sequence, not…
What “true color” means in a welding helmet A true-color auto-darkening lens uses a filter that shows the weld area with less of the strong green cast common in older…
Low-amperage TIG exposes weaknesses in a welding helmet that are easy to miss with MIG or high-current stick welding. A small tungsten arc can be dim, especially when welding stainless…
A large viewing area helps when MIG welding long seams, working around corners, or keeping a puddle in sight without moving your head. It does not automatically make a helmet…
Bright outdoor fabrication exposes a welding helmet to problems that are less common in a dark shop. Sunlight can make it harder to judge the arc, reflective steel can confuse…
Plasma cutting leaves a heat-affected zone (HAZ) beside the cut face. On mild steel, that zone may be only a fraction of a millimeter wide, but it can still contain…
Why moisture matters in plasma cutter air lines Plasma cutters need clean, dry compressed air to make a stable arc and a consistent cut. Water in the line can cause…
Pierce delay is the time a CNC plasma cutter waits after starting the arc before it begins moving along the cut path. The pause lets the arc pierce the plate…
A circle guide turns a plasma cutter’s torch into a pivoting tool: a center point holds the radius, while the torch travels around it. It can make a cleaner, more…
