Welding Supplies
For over 20 years the Hocon Gas has been committed in giving exceptional energy product and commitment to outstanding customer service. It has been supplying industrial, medical, specialty and cryogenic gases. This family-owned business supplies welding and safety supplies with an unprecedented passion for the industry.

The Hocon Industrial Gas arm of the company specializes in welding supplies. It offers welding gases and other supplies needed for welding projects. The company currently carries the products of ESAB and Lincoln.

The company offers ESAB Cored Wire Electrodes, ESAB Covered Electrodes, ESAB Solid Wire and Rod, ESAB Submerged Arc Wire and Fluxes, and ESAB Welding Filler. In addition to the ESAB Products, the company also sells Lincoln Welding Consumables.

The ESAB Cored Wire Electrodes covers an extensive array of Dual Shield, Mild Steel and Low Alloy cored wires. It also carries Coreweld metal cored wires and Coreshield self shielded cored wires.

The ESAB Covered Electrodes possess quality control standards that produce excellent results. Each premium electrode is manufactured in an ASME certified quality assurance system that insures that the product is of exceptional grade. This category carries the SUREWELD® Mild Steel Electrodes line, ARCALOY® & ESAB Stainless Electrodes and ARCALOY® & ESAB Nickel Steel Electrodes line, the NICKEL-ARC® Cast Iron Electrodes line, and the WEAR-ARC® Hardfacing & Build-up Electrodesline.

The ESAB Solid Wire and Rod Electrodes supplies the arc welding industry with an best quality wires and alloys that ensures higher wire feed speed and greater productivity. This category covers the Mild Steel Wires, the SPOOLARC® Low Alloy Wires, the OK® Autrod Stainless Steel GMAW Wires, the ARCALOY® Nickel Steel Solid Wires, the ESAB Aluminum Solid Wires, the Tigrod LA-GTAW Products and the Tigrod Stainless Steel GTAW Products

The ESAB Submerged Arc Wire and Fluxes has over 15 classifications of Spoolarc wires for submerged arc welding carbon and low alloy steels. Each submerged arc wire is manufactured under a strict ISO 9001 program. This ensures that the products are of the finest quality available. This category carries the Mild Steel & Low Alloy Submerged Arc Wires and Fluxes, the OK® Autrod Stainless Steel Submerged Arc Wires and Fluxes, the Stainless Cladding Strip/Flux Products, and the Nickel Steel Cladding Strip/Flux Products.

The ESAB Welding Filler provides other electrodes, cored wires, Stainless Cladding Strip and Submerged Arc Wire/Flux.

Like the ESAB products, the Lincoln Consumables are Welding Wire, Flux and Rods products. Lincoln Electric carries Stick electrodes, Mig wires and Tig Cut Lenghts, Metal-cored wires, Self-shielded (Flux-cored), Gas-shielded (Flux-cored), Submerged Arc, Stainless and High Alloy, Nickel Alloys, Hardfacing, Aluminum Mig and Tig, Pipeliner, and Murex.

Aside from providing welding gas to its customers, Hocon is a welding supply store that carries and provides exceptional welding supplies to its customers.

Welding Gases
Gas welding is a process done by utilizing the heat of a flame coming from a welding torch. The utilization of welding gases plus the mixture of oxygen in the proper ratio and flow rates evokes the combustion process at the required temperature. The heat produced by the flames melds the edges of the objects together.

Gas welding may use an assortment of fuel gases, the most common of these gases is acetylene. Other gases that can be used are argon, hydrogen, and propane. Some welding processes may use different kinds of gases in their mixes.

Acetylene (C2H2) is a compound of carbon and hydrogen. It is a colorless and is highly flammable. One distinguishing fact about this gas is that it has a garlic-like odor. Acetylene is mainly used for chemical synthesis. A combustion of Oxygen with Acetylene produces a flame that is over 3300 °C (6000 °F) which is ideal for oxyacytelene gas welding, gas cutting, and heat treating. It is commonly used to join mild steel permanently. Essential equipments used for the oxyacetylene welding process are the torch, the hoses, the gas regulators and the flame traps or the flash arrestors. Since Acetylene is a highly flammable gas, it has the potential to catch fire and to explode. It can also cause suffocation when inhaled in large quantity.

Argon (Ar), on the other hand, is a colorless, odorless, tasteless, noncorrosive, nonflammable, and nontoxic gas. It is a highly stable chemical element both in its liquid and gaseous forms. Argon is used widely as a fill gas in incandescent and fluorescent lamp. It is used as such because it does not react to the filament of the light bulbs even at a high temperature. Aside from that, argon is mostly used for applications like arc welding, steel making, heat treating and electronics manufacturing. In its welding application, straight argon is used in TIG welding as a shielding gas. In MIG welding however, argon is combined with CO2 when used as a shielding gas. Among the shielding gases, argon is the most stable arc and also has the most effective cleaning action. Argon provides the welders good control of the welding arc and the puddle. While Acetylene runs the risk of an explosion, Argon being a stable compound is non-flammable. However, high pressure suffocation is still a hazard.

Next on the list of industrial gases is Hydrogen. Of all the gases, Hydrogen is the lightest. It is most commonly found in nature as one of the common components of an organic compound. It is also the most abundant element in the universe, notably the sun and the stars has hydrogen in their composition Hydrogen is widely used in chemical engineering processes in oil refineries, among other industries.

The soap making industry uses Hydrogen to turn inedible grease into soap. In the welding industry, Hydrogen serves as a fuel in underwater oxy-hydrogen torches. It is also used for metal welding and brazing. In addition to that hydrogen is used to enhance plasma welding and cutting operations. Hydrogen is a non-toxic gas, however, it is extremely flammable and can also cause suffocation.

And last on the list of welding gases is Propane. Propane (C3H8) is a colorless and flammable liquid gas. In its natural state, Propane is also an odorless gas. Since its odorless it serves a potential danger when not detected earlier for leaks. So Propane manufacturers decided to add an odor additive, usually mercaptan, to Propane for safety purposes. Propane is more commonly known as a cooking gas since it is widely used as such. It is also used to power heating appliances around the house. In welding, Propane is used combined with oxygen or air. Propane is widely used in industrial applications such as, flame heating, soldering, brazing and flame cutting processes. Propane is known to be highly explosive and like the rest of the gas it can also cause suffocation.

Welding Gases are essential in the gas welding industry. To know more about these welding gases it is advisable to check wih your local industrial gases supplier.
