TECH TIPS: is a light, medium or heavy duty torch best for your application?

Oxyfuel equipment manufacturers generally classify torches and regulators as light-duty, medium-duty, heavy-duty or extra-heavy-duty based on the gas flow capacities of the torch, tip and regulator. If you’re looking for the right torch for your needs, here’s when to use each type.

When to Use Light-Duty Torches

If you’re welding smaller and thinner steel applications – that don’t require a high volume of gas flow – a light-duty torch can handle the job. A light-duty torch is also easier to maneuver, making it key for tight space and working at intricate angles, such as brazing around a pipe circumference or welding detailed metal art projects. 

When to Use Medium-Duty Torches

A fabrication facility, as well as those in farming, general repair, mechanic or a “garage user” will need at least the capabilities of medium-duty. A good place to start is by reviewing tip selection charts to match the tip size and flow rates to your application / process, then select the corresponding torch or outfit. Cutting and welding tips are classified by orifice size, and heating tips are classified by BTUs per hour. 

When to Use Heavy-Duty Torches

If you’re welding pipelines or you’re working in construction, shipbuilding, heavy equipment repair, or scrap and demolition, a heavy-duty outfit and related torches and tips are essential. 

When you choose a tip size, remember that effective cutting/heating/welding flame requires the burning velocity based on a precise mix of oxygen and fuel. This avoids a poor cut and the related time and money wasted fixing it.  

In addition, don’t set gas flow rates outside of recommended parameters. Incorrect flow rates can quickly lead to overheating, backfires, ragged cuts and excess slag.
