Frequently Asked Questions

What's included in a Port-A-Torch kit and what can I do with it?

A Port-A-Torch kit is a portable oxy-fuel outfit that typically includes the cutting/welding torch body, oxygen and fuel gas hoses, an oxygen regulator (rated to approximately 14 bar / 200 psi max output), a fuel gas regulator (approximately 2 bar / 30 psi max output), assorted cutting and welding tips, and a carrying case or tote. Oxy-fuel kits can cut carbon and low-alloy steel plate and pipe, weld thin steel, heat and bend metal, and braze. They run off standard compressed gas cylinders — the kit attaches to whichever cylinder size you have on hand.

What fuel gas should I use with my Port-A-Torch kit — acetylene, propane, or something else?

For welding and cutting, acetylene is the traditional choice because the oxy-acetylene flame reaches approximately 3,480°C (6,300°F) — the highest temperature of any fuel gas — and produces the neutral flame required for welding mild steel, stainless, and aluminum. Propane and LP gases produce good cutting flames (slightly lower temperature) at a lower cost per cubic foot and are well-suited for cutting and heating applications. Propylene blends are also available for cutting. The torch nozzle must be matched to the fuel gas in use — a nozzle designed for acetylene produces a different mix ratio than one designed for propane.

What materials can a Port-A-Torch kit cut, and what can't it cut?

Oxy-fuel cutting works very well on mild and low-carbon steel, and produces good results on low-alloy steels. It does not work on stainless steel (the chromium oxide layer prevents the iron-oxygen reaction from sustaining), aluminum, or copper-based alloys — these require plasma cutting or mechanical methods instead. For stainless steel, a flux injection system can be added to the oxygen jet to assist cutting, but cut quality is poor. All common pipe and structural steel (A36, A53, A106, API 5L) cuts cleanly with oxy-fuel.

Are flashback arrestors required on a Port-A-Torch kit?

Flashback arrestors are strongly recommended and required by many safety codes (OSHA 1910.253, CSA B256). A flashback occurs when the flame burns back through the hose toward the regulator or cylinder — arrestors contain a check valve and thermal cut-off that stop the flame before it reaches the gas supply. Install one at the torch inlet for each gas (oxygen and fuel), and ideally a second set at the regulator outlets. The Air Products handbook specifies that hoses must be fitted with hose protectors (flashback arrestors) at the torch connection. Never operate an oxy-fuel kit without them.

How do I light and adjust a Port-A-Torch safely?

Before lighting, open both cylinder valves and set the working pressures on the regulators with adjusting screws. Open the fuel gas valve on the torch slightly, then ignite with a flint lighter (never a match or cigarette lighter — you'll burn your hand). Open the oxygen valve gradually until you reach the desired flame type: excess fuel gives a carburizing flame; excess oxygen gives an oxidizing flame; equal proportions give a neutral flame (visible as a sharp inner cone with no feathering). Always light the fuel first, then add oxygen. To shut down, close the cutting oxygen first, then the fuel, then the oxygen — this order purges both passages and prevents backfire.
