Composed of nitrogen, oxygen and carbon dioxide, Extendapak ® food gas mixtures greatly reduce microbial growth, delay spoilage and slow enzymatic and biochemical degradation. Protect product flavour, aroma and texture, and extend shelf life without the use of preservatives.

Ensure precision high quality welds in the most pressing environments with Linde’s ​HeliStar ® helium-enhanced blends. Available in a variety of precise formulas, there’s a ​HeliStar​ gas to meet your GMAW, GTAW, PAW and laser welding needs.

These hydrogen-enhanced blends are available in a wide range of precision formulations for top-quality welding and cutting applications. So if you’re looking to enhance the quality of your welds in GMAW, GTAW or plasma welding, gouging or cutting applications, there’s a ​HydroStar ® blend to meet your demands.

Our ​LaserStar​ ™ gases are used to generate the beam in a wide variety of carbon dioxide lasers. When used with a properly designed delivery system, ​LaserStar​ blends can help you achieve optimum laser performance, maximum operating duty cycle, and minimum maintenance costs.

Spend more time welding and less time cleaning with our ​Mig Mix Gold​ ™ Blends for greater productivity. Users report reduced spatter, less fume with little or no residual slag, so there is little to no post-weld cleanup.

Our ​RoboStar® blends for robotic welding are designed with a unique formulation that make them fit for all-position welding. These blends can also be used with a full range of metal transfers including short-circuiting, pulsed and conventional spray.

Burning hotter than other fuel gases, our ​StarFlame​ ™ C Cutting Gas cuts quicker. And with the flexibility to deliver good results even when the cutting tip is too close to the workpiece or its distance opens up to two inches during cutting, it’s a great choice for hand-torch cutting.

Improve your operation with our ​StarGold​ ™ blends. These mixtures help you produce less over-welding, reduce grinding, decrease fumes, and increase travel speeds. Get better weld bead shape and excellent weld metal mechanical properties with ​StarGold​ blends.

Designed to meet the demands of your specific GMAW application, our ​Stargon​ ™ blends are especially useful for those who use a number of GMAW process variations because they can be used for short circuiting, globular, spray and pulsed arc transfer.

We offer a wide range of quality refrigerant and air-conditioning gases, together with cylinders for recapturing and reclaiming refrigerants, to support the ever-changing needs of air-conditioning and refrigeration professionals from coast to coast.
