About Harris

The company's extensive product line includes welders, welding guns & torches, plasma cutters, gas equipment, welding helmets, protective gear, filler metals and related accessories. Harris flowmeter / regulators are combination devices that serve the dual function of regulating gas flow as well as measuring the flow rate. They feature a one-piece encapsulated seat design with an internal filter to minimise the chances of gas leakage while trapping impurities present in the gas stream. They are further integrated with the neoprene diaphragm for better pressure control and a sensitive needle valve with fingertip controls for highly accurate flow settings. These single-stage devices feature a 1-1/2 inch steel dual-scale gauge to display the two readings simultaneously and are compatible with gases like carbon dioxide and argon. The brand's cutting tips are designed for use with machine cutting torches in high-speed cutting applications. They feature a two-piece design that helps maximise kerf to produce high-quality cuts while reducing heat input. These units feature a chrome-plated brass outer shell which is engraved with the model number and tip size for easy identification. These tips are ideal for fuels including natural gas, propane and MAPP (methylacetylene-propadiene propane) and are available in sizes ranging from 1 to 5 inches.

Things to Consider

Cross-Reference Alternatives

Harris MPNs cross individual references to the equivalent Uniweld and Miller-Smith Equipment model numbers for regulators and cutting torches. So, if you're looking for a competitor item that is either out of stock or obsolete, chances are Raptor Supplies has the equivalent Harris products available.

Shipping

These Harris products range from small to large sizes. They may require careful packaging as some items might get damaged while shipping. Hence, these items are delivered by courier shipment and air freight for minimum downtime.

Harris Competitive Advantages

Stay-Silv Black Brazing Flux

This flux is an all-purpose, high-temperature paste flux used in silver brazing. It is specifically designed for applications where the material is subjected to rapid, localised heating or where longer brazing times are seen. It turns transparent when it reaches the brazing application temperature, indicating the correct time for braze wire applications. Once dried, the flux residue can be removed with a hot water rinse. This paste can be used with stainless steel, carbide, and heavy parts with prolonged heating cycles.

Frequently Asked Questions

In which direction can I mount the flowmeter / regulator?

Harris combination flowmeter / regulator must be mounted vertically, with the gauge faces and adjustment knob positioned vertically, either facing upwards or downwards. This orientation is useful in applications where space is limited.

What is meant by kerf?

When a cutting torch is used to cut through a material, it removes a small amount of the material as it passes through. The width of this removed material, or the gap created by the cutting torch, is known as the kerf. The width of the kerf can vary depending on the type and thickness of the cutting torch, the material being cut, and the cutting technique employed. For example, a narrower kerf indicates a more precise and efficient cut as it removes less material and minimizes waste.

How do Flashguard check valves work?

Flashguard check valve's working is based on a combination of mechanisms, including a flame arrestor, a check valve, and a thermal cut-off valve. The flame arrestor blocks the flame or spark from propagating through the valve, while the check valve prevents the backflow of gases. If a flashback occurs, the thermal cut-off valve activates and cuts off the gas flow, further preventing the flame from continuing down the line.
