Benefits of Ferromaxx® 7

Reduced Costs

The specially designed formulation ensures ultra-low levelsof spatter meaning less wasted wire and less time spent on weld clean-ups withFerromaxx® 7. The versatility of Ferromaxx® 7 allows a broader range ofapplications than most equivalents, being suitable for up to 10mm metalthicknesses.

Fewer Rejects

Ferromaxx® 7 provides excellent weld penetration and arcstability.

Safer Working Environment

Because ozone is a health hazard which cannot always beremoved by fume extraction equipment, Ferromaxx® 7 has been developed to givelow ozone exposure levels. The result - a gas that provides a better workingenvironment as well as improved productivity and fewer rejects.

Optimal Mode of Supply

Ferromaxx® 7 is available in a full range of cylinder sizes,packs and tanks in various pressures to suit every business.The versatility of Ferromaxx® 7 terms of metal thickness andweld parameters contributes to reduction in stock required.

See the Range

Choose the innovative Integra® cylinder – smaller, safer, and easier to use.  The cylinder is filled with 30 litres at 300 bar pressure meaning that it often outlasts conventional 47 litre, 200 bar equivalents. 

The quick-connecting Integra® gas flow optimisers are pre-set to specific gas flow rates to control flows and allow for rapid cylinder changeovers.


If you prefer more volume in your cylinder, then choose Ferromaxx® 7 gas in a larger 47 litre, 300 bar cylinders to maximise welding time and minimise cylinder handling.
