I take a lot of calls regarding using Oxygen + Propane or Oxygen + Propylene instead of Acetylene + Oxygen. Well the short answer to the Title question is, “Yes” and “No”. Sorry its ambiguous, but it all depends what you want to do!  Let me explain! Fuel Gas Options Oxygen + Fuel Gas kits used […]

I’ve already written an article Titled Can I use Propane or Propylene Instead of Acetylene so I won’t go over that ground again here. Instead I want to concentrate on the equipment differences and what you need to change when swapping from Oxy Acetylene to Oxy Propane or Propylene. Gas Welding Equipment OK, so you […]

Is Propane any good? YES! It’s a great gas! The only real downside to Propane is that you can’t weld with it. Pretty much everything else can be done. With the right Torch, Oxy/Propane is great for Heating, Brazing, Silver Soldering etc. How Propane Works in practice Propane is a liquified gas and is stored […]

No Rent Gas Cylinders have become very popular in recent Years. For those who cannot justify the cost of Renting a cylinder, but find disposable cylinders expensive, no rent gas cylinders are perfect. Rented Gas Cylinders Renting the Gas Cylinder has always been the traditional way of accessing Industrial type Refillable cylinders. Gas fills are […]

“How do I dispose of empty Gas Cylinders” is a question I get asked a lot! Much will depend on the type of cylinder and the gas contained within it. Types of Gas Cylinder Refillable cylinders should always be returned to the supplier for recycling. Given there’s often a deposit on refillable cylinders it makes […]

Mig Welding Gas is required because it’s essential to keep Oxygen from the weld pool. Shielding gas does this by replacing the Oxygen containing air that’s all around the weld pool. Categories of Mig Welding Gas Mig Welding Gas falls into two basic categories, “Inert” & “Active”. Inert means the gas has no effect on the […]

What is the best gas for Mig welding mild steel is a frequent question I get asked on the phone. Unfortunately, there’s not a simple, straightforward answer as it rather depends on a number of factors! The three key factors are: I guess you can combine 1 & 2. Disposable Gas Cylinders If you’re using […]

What’s the right Gas Flow Rate for a Mig is a question we get asked a lot, but like many things in welding, there’s no definitive answer. The correct Gas Flow Rate for a Mig will depend on a number of factors: Having said all that, I understand you need a start point, so I’ve […]

I get asked “can you use the same gas for Mig and Tig” a LOT! Sadly, the answer is NO. Gas for Mig Welding Both Mig and Tig Welding require gas to protect the weld pool from Oxygen and often to cool the Torch but these are not the only functions it performs with Mig […]
