Nitrogen (Oxygen free) 230bar supplied in multiple cylinder sizes (2.1m3 to 9.8m3 capacity) Nitrogen is a non-corrosive, inert gas and is compatible with any common metals provided the equipment is designed to with stand the process pressure of a compressed gas cylinder. Inert to nearly all substances at ambient temperatures and moderate conditions. Nitrogen keeps laser-cut faces oxide-free due to the chemical inertness to react with the atmosphere. At higher temperatures, nitrogen can react to form metal nitrides. Nitrogen gas is only slightly soluble in a wide range of liquids and is therefore used to flush unwanted gases from solutions. Reduces internal degradation of the rubber in tyres due to oxidisation. As a cryogenic liquid, nitrogen can be used to thermally contract metals.

Combining helium with argon these mixtures greatly improve welding speeds, increase deposition rates and reduce preheat requirements. Alushield will help a skilled welder to produce smooth, clean, defect free welds in all grades of aluminium. Alushield Heavy Alushield Heavy is a mixture of 75% helium and 25% argon developed primarily for the MIG welding of aluminium above 10mm and TIG welding of aluminium above 6mm thick.It produces the most fluid weld pool of all the Alushield gases and this gives deep, broad weld profiles with much lower reinforcement levels than the other gases, especially argon. On thick sections (12mm and above) an added advantage of Alushield Heavy is that plate edge preparation angles are reduced without losing penetration.This is due to Alushield Heavy's ability to punch into a material with its far higher energy transfer. Not having to use such a large edge preparation angle reduces the amount of wire required to complete joints and the number of welding passes, a key part in cutting production costs.

Awaiting image Argon/Hydrogen 2.5% H2, Ar has been developed to have improved characteristics over argon suited to manual applications, welders find the more fluid weld pool easier to control giving flatter, smoother weld beads. Easier and faster to use than argon, the small amount of hydrogen helps to scavenge any oxygen from around the weld area, producing a bright clean weld and smooth surface finish. The hydrogen content of the shielding gas stiffens the welding arc and increases the fluidity of the weld pool, making it easier to produce a neat, tidy weld bead. Improved fluidity increases welding speed compared to argon, resulting in lower weld costs.

Used for welding construction work on steel greater than 10 millimetres thick, Argoshield Heavy has a much higher Carbon Dioxide content and consistently produces strong, reliable welds with a deep, bowl-shaped penetration. This product is particularly suited to work where large numbers of multi-pass welds in spray transfer are required on heavy sections. The product's excellent arc stability and precise formulation for this type of work delivers faster welding speeds which reduces production costs. Argoshield Heavy is ideally suited for heavy engineering and structural work including shipbuilding and repair, boiler manufacturing and the production of bigger, stronger vehicles. Combines 2% Oxygen, 20% Carbon Dioxide, balance Argon Specially formulated for MIG welding constructional steel work of mild steel greater than 10mm thick Ideal for heavy engineering and structural work such as shipbuilding and repair, heavy vehicle and boiler manufacturing Is suitable for a wide range of applications from welding thick-walled pipes and pressure vessels to earth-moving equipment High carbon dioxide content gives mild steel welding good rounded penetration profiles, producing consistently reliable and strong welds with a deep, bowl-shaped penetration.

Argoshield Light is specifically formulated for MIG welding sheet and thin sections of mild steel less than 4mm thick. The low levels of carbon dioxide and oxygen in the weld reduce the risk of burning through and leaving holes in the weld area. The addition of oxygen improves the flow of the molten weld metal producing flatter welds with lower levels of reinforcement. This can greatly reduce the need to machine or grind down the reinforcement, which is a known stress raiser, reducing production costs. Argoshield Light has excellent arc stability minimising the amount of spatter produced. Reduced spatter means less welding wire being wasted, as well as shorter clean up time. This makes the product ideal for welding components that are painted or powder coated after welding. The faster welding speeds achievable with this gas coupled with a low heat input also help to reduce welding distortion. Benefits Combines 2% Oxygen, 5% Carbon Dioxide, balance Argon Formulated for MIG welding sheet and thin sections of mild steel less than 4mm thick Ideal for duct and sheet-metal engineering industries A suitable gas in automotive component manufacturing and vehicle repair as it provides dip transfer in all positions with solid wire The oxidising potential of this mixture has a tendency to produce welds with a black surface film. In many stainless steel applications, this type of surface finish would be considered unacceptable and removal of the surface film would be required. Cleaning away this residue can be both time-consuming and costly. Due to this, other products such as the BOC Stainshield range of gases would be recommended.

99.995% Methane

99.995% Methane (Grade 4.5)

Nitrogen (Oxygen free) 230bar supplied in multiple cylinder sizes (2.1m3 to 9.8m3 capacity) Nitrogen is a non-corrosive, inert gas and is compatible with any common metals provided the equipment is designed to with stand the process pressure of a compressed gas cylinder. Inert to nearly all substances at ambient temperatures and moderate conditions. Nitrogen keeps laser-cut faces oxide-free due to the chemical inertness to react with the atmosphere. At higher temperatures, nitrogen can react to form metal nitrides. Nitrogen gas is only slightly soluble in a wide range of liquids and is therefore used to flush unwanted gases from solutions. Reduces internal degradation of the rubber in tyres due to oxidisation. As a cryogenic liquid, nitrogen can be used to thermally contract metals.

Stainshield Light is ideal for welding stainless steel up to 3mm in thickness and produces clean, bright welds with a flat profile. Specially formulated for dip transfer with solid wire, Stainshield Light produces minimal spatter, low distortion and provides excellent positional characteristics (flat, horizontal, vertical or overhead) ensuring even the most complex welds can be performed.

The BOC Stainshield range consists of a mix of argon, helium and carbon dioxide shielding gases for MIG welding stainless steel, and an argon-hydrogen mixture for TIG welding austenitic stainless steels.

Stainshield TIG gas has been developed to have improved characteristics over argon suited to manual applications, including TIG welding austenitic stainless steel (300 series). Welders find the more fluid weld pool easier to control giving flatter, smoother weld beads. Primarily used for plasma welding of austenitic stainless steels. The thicker the section of material to be welded, the higher the hydrogen content in the plasma shielding gas. Easier and faster to use than argon, the small amount of hydrogen helps to scavenge any oxygen from around the weld area, producing a bright clean weld and smooth surface finish. The hydrogen content of the shielding gas stiffens the welding arc and increases the fluidity of the weld pool, making it easier to produce a neat, tidy weld bead. Improved fluidity increases welding speed compared to argon, resulting in lower weld costs.
