SMITH EQUIPMENT

Smith Equipment is a manufacturer of gas apparatus for welding, cutting, heating, and analytical applications. The company was founded in 1916 in Minneapolis, Minnesota, and has since built a product line that includes oxy-fuel torches, gas regulators, flowmeters, cutting tips, and specialty gas-control devices. Smith Equipment is known for its line of high-purity regulators, flow gauge regulators, and handheld cutting torches, which are used in industrial fabrication, shipbuilding, maintenance, and laboratory environments. The brand's product families cover several key categories: gas regulators (including two-stage high-purity and flow gauge models), handheld cutting torches (both 90° and 180° head configurations), cutting tips, and related accessories. These products are used with a range of gases, including argon, carbon dioxide, oxygen, and fuel gases such as acetylene and propane. Technical buyers will find that Smith Equipment regulators are available with CGA inlet connections (e.g., CGA 580 for inert gases, CGA 320 for carbon dioxide) and outlet connections such as 1/4" tube or 5/8"-18 female right-hand. High-purity models feature stainless steel diaphragms and built-in safety relief valves, with output pressures up to 50 psig. Handheld cutting torches are offered in lengths from 21 to 48 inches, with 9/16"-18 connection threads, and are designed for oxy-fuel cutting of ferrous metals. 3G Electric supplies the Smith Equipment line to industrial and analytical customers worldwide. The catalog includes regulators for gas chromatography and analytical applications, flow gauge regulators for welding and fabrication, and cutting torches for heavy industrial cutting. 3G Electric provides access to these products with specifications and part numbers, and supports procurement teams with quote requests and order fulfillment. The product range is suitable for plant engineers, maintenance managers, and procurement specialists who require gas-control equipment that meets defined connection standards and pressure ratings. Smith Equipment's long history in gas apparatus manufacturing is reflected in the availability of replacement parts and accessories that maintain compatibility across the line. 3G Electric's role is to make these products available globally, with a focus on accurate part identification and responsive service.

Frequently asked questions

Common questions about SMITH EQUIPMENT from 3G Electric.

What is the difference between the Smith Equipment high-purity regulator (SKU 45PW27) and the flow gauge regulators (SKUs 5EFY1, 5EFY2, 5EFY3)?

The high-purity regulator (MPN 221-0209) is a two-stage regulator with a stainless steel diaphragm, CGA 580 inlet, and 1/4" tube outlet, rated to 50 psig. It is designed for analytical applications such as gas chromatography, where contamination control is critical. The flow gauge regulators (MPNs 31-50-580, 31-50-580-6, 31-50-320) are single-stage models with a direct-reading flow gauge, CGA 580 or CGA 320 inlets, and 5/8"-18 F RH outlets. They are used for argon or carbon dioxide in welding and fabrication, providing precise flow control rather than high-purity delivery.

What are the available lengths and head angles for Smith Equipment handheld cutting torches?

Smith Equipment handheld cutting torches are available in several configurations. The SC940 has a 48-inch length and a 180° head. The SC929 has a 21-inch length and a 90° head. The SC369 has a 36-inch length and a 90° head. The SC360 has a 36-inch length and a 180° head. All models feature a 9/16"-18 connection thread and are designed for oxy-fuel cutting of ferrous metals. The 90° head is suited for confined spaces, while the 180° head provides straight-on access for heavy cutting.

What gases are compatible with Smith Equipment flow gauge regulators?

Smith Equipment flow gauge regulators are configured for specific gases. The 31-50-580 and 31-50-580-6 models are designed for argon service, with a CGA 580 inlet. The 31-50-320 model is designed for carbon dioxide service, with a CGA 320 inlet. These regulators have a 5/8"-18 female right-hand outlet. The direct-reading flow gauge allows the operator to set and monitor flow rate. They are commonly used in welding, fabrication, and other applications requiring controlled gas delivery.

What are the inlet and outlet connections on Smith Equipment high-purity regulators?

The Smith Equipment high-purity two-stage regulator (MPN 221-0209) has a CGA 580 inlet and a 1/4" tube outlet. The CGA 580 connection is standard for inert gases such as argon, nitrogen, and helium. The 1/4" tube outlet allows connection to analytical instrumentation or tubing systems. The regulator includes a built-in safety relief valve and a stainless steel diaphragm. It is rated for output pressures up to 50 psig and is suitable for air and inert gas applications requiring contamination-free delivery.

Can Smith Equipment cutting torches be used with alternative fuel gases?

Smith Equipment handheld cutting torches are designed for oxy-fuel cutting of ferrous metals. They are typically used with oxygen and a fuel gas such as acetylene, propane, or natural gas. The torch itself is compatible with these fuel gases when used with the appropriate cutting tips and regulators. The 9/16"-18 connection thread is a standard fitting for Smith-style torches. For specific fuel gas compatibility, refer to the torch's operating instructions and the cutting tip manufacturer's recommendations.

What is the significance of the 'Smith-Style' designation on these cutting torches?

The 'Smith-Style' designation indicates that the torch uses the Smith Equipment connection geometry and tip compatibility. Smith-style torches have a 9/16"-18 connection thread and accept Smith-style cutting tips. This standardization allows interchangeability with other Smith-style components and accessories. The torches are available in various lengths and head angles to suit different cutting positions and access requirements. The designation helps buyers identify compatible consumables and replacement parts.
