What is the difference between MIG, stick and TIG welding?

There are a few main types of welder and welding techniques, and each is suited to a few specific applications. 

MIG welding is the most versatile and easiest type of welding to learn. It can be applied to a variety of materials and thicknesses but the welds aren’t as strong as stick/arc welds, or as clean as a TIG weld. MIG welding usually requires carbon dioxide (CO2). 

TIG welding is perfect for producing precise welds, but has a steeper learning curve and more limited applications than MIG. Generally used for welding thinner materials to produce welds that look perfect. TIG welding usually requires argon.

Arc or stick welding is for heavy duty applications where creating the strongest welds possible or welding thick material are required. Thanks to the high arc temperature, you can also stick weld materials like cast iron that you can’t with a MIG or TIG welder.

Benefits of owning a welder

Getting your own welder puts you in control. You’ll be able to:

• Repair or fabricate metal parts at home or on-site
• Save on labour and repair costs
• Take on your own custom builds or creative projects
• Learn a valuable hands-on skill
• Keep working without waiting on trades or workshops

It’s a worthwhile investment whether you’re working professionally or building up your workshop.

Key features to consider when buying a welder

Before choosing a machine, think about how and where you’ll be using it. Here are a few things that matter:

• Welding process: Choose between MIG, TIG, Stick, or go all-in with multi function welders
• Power output (amperage): Higher output helps with thicker metals
• Duty cycle: This tells you how long the machine can run before needing a rest
• Input voltage: Make sure your power source matches your machine
• Portability: Lighter machines are easier to move, while heavier models are built to stay put
• Material compatibility: Some welders are better for aluminium, stainless steel or mild steel
• What’s included: Welding combo kits can be great value and include leads, clamps or helmets

Safety considerations when welding

Welding puts out light, heat and fumes, so it’s no job to take lightly. Make sure you’re always working with:

• A high-quality welding helmet
• Heat-resistant gloves
• Flame-retardant clothing (long sleeves and pants)
• Good ventilation or fume extraction

Frequently Asked Questions (FAQs)

What does the duty cycle of a welder mean?

It’s how long your welder can run in a 10-minute window without overheating. A 40% duty cycle at 200 amps means you can weld for 4 minutes, then it needs to cool down.

What type of welder do I need for welding aluminium?

TIG welders are often the go-to, but some mig welders with the right wire and settings can do the job too.

What safety equipment is essential for welding?

You’ll want a helmet, gloves, flame-retardant clothing, and proper ventilation. Take a look at our welding safety products for everything you need.

What power output (amperage) do I need for my welding projects?

For general use, 140A to 180A works well. Thicker materials or structural work may need something in the 200A+ range.

What is a multi-process welder?

A machine that lets you weld using MIG, TIG, and Stick—all from one unit. Great if you need flexibility or work across different materials.

Do I need special training to use a welder?

No licence is required, but you should know the basics. Training courses, TAFE, or manufacturer guides are a good place to start.
