Choosing the Right Welder for Your Needs
With several types of welders available, it can be tricky to determine which is the right one for your particular welding projects. Here's an overview of some of the most common types of welders and considerations for choosing the best option for your needs.
Stick Welders
Stick welders, also known as arc welders, use an electric arc between a consumable stick electrode and the metal to melt the materials being joined. Some pros of stick welders:
- Inexpensive to purchase and operate
- Portable and versatile for welding outdoors or in locations with limited access to power
- Allow welding of dirty or rusty metals
- Ideal for thicker metals
Stick welders may not be the best choice for precision welds or welding thinner metals. The welding process also requires more clean-up of slag.
MIG Welders
MIG (metal inert gas) welders feed a continuous solid wire electrode through a welding gun and regulate the arc using an inert gas like argon or CO2. Benefits of MIG welders include:
- All-position and multi-purpose welding
- Good for welding thinner gauge metals
- MIG welders are easier to learn than stick welding
- Minimal slag and spatter
MIG welding may not work well outdoors due to drafts affecting the inert gas shield. The equipment is also bulkier and more expensive than stick welders.
TIG Welders
TIG (tungsten inert gas) welders use a non-consumable tungsten electrode and inert gas like argon to generate the weld area arc. TIG welders allow for:
- Very high quality, precise welds
- Suitability for thinner metals
- Minimal post-weld cleaning required
However, TIG welders require the most skill to operate and tend to be among the most expensive type of welder.
Multi-Process Welders
Many modern welders are designed to support multiple welding processes. This allows switching between options like MIG, stick, TIG, and flux-cored welding using the same machine. Benefits include:
- Versatility - can weld a broad range of materials and thicknesses
- Convenience of having all processes in one welder
- Takes up less space in home or shop
Multi-process welders cost more than single-process options but can be a smart long-term investment for hobbyists and professionals who work with varied welding projects.
Key Considerations
When choosing the right type of welder, keep these key factors in mind:
- Your intended welding application and projects
- Types of metals and material thicknesses you need to weld
- Your skill level and experience
- Features like portability, power supply, and duty cycle
- Initial and ongoing costs
Taking the time to evaluate your needs and welding environment will help guide you to selecting the welder that's right for you. And don't be afraid to ask welding equipment suppliers for advice too!

Stick Welders vs MIG Welders vs TIG Welders
When exploring your options for welders, three of the most common types you'll encounter are stick welders, MIG welders, and TIG welders. Understanding the key differences between these three welding methods can help you determine which process may work best for your specific projects and needs.
Stick Welding
Stick welding, also known as shielded metal arc welding (SMAW), is one of the oldest and most straightforward welding techniques. It uses an electric arc generated between a consumable stick electrode and the base metal to produce coalescence. Some advantages of stick welding include:
- Inexpensive equipment with simple operation
- Portable and versatile for welding outdoors or in remote sites with limited access to power
- Can weld dirty or rusty metals
- Ideal for welding thicker materials
One downside is that stick welding can produce more slag and spatter that requires chipping and cleaning after welding. The welding process overall has a slower pace than other methods.
MIG Welding
MIG (metal inert gas) welding feeds a continuous solid wire electrode through a welding gun, while an inert shielding gas like argon or CO2 protects the weld pool. Benefits of MIG welding include:
- Good versatility and ability to weld in all positions
- High welding speeds compared to stick welding
- Easier to learn for beginners than stick or TIG
- Minimal slag and spatter
MIG welding isn't well-suited for outdoor uses where drafts can disrupt the shielding gas flow. The equipment is also bulkier and more complex than a basic stick welding setup.
TIG Welding
With TIG (tungsten inert gas) welding, an arc forms between a non-consumable tungsten electrode and the workpiece, while an inert shielding gas like argon protects the weld puddle. TIG welding allows for:
- Very high quality, precise welds for thinner materials
- Great control and ability to weld exotic metals
- Minimal post-weld cleaning required
On the downside, TIG welding has a steeper learning curve and requires the welder to manually control the welding torch in one hand and the filler rod in the other hand.
Comparison
| Stick Welding | MIG Welding | TIG Welding | |
|---|---|---|---|
| Equipment Cost | Low | Moderate | High |
| Complexity | Simple | Moderate | Complex |
| Welding Speed | Slow | Fast | Moderate |
| Ideal Materials | Thicker and dirty metals | Thinner metals and alloys | Thin exotic metals |
Choosing Your Process
When selecting between stick, MIG, and TIG welders, key factors to consider include:
- Types of projects and applications
- Metals you need to weld
- Available power supply
- Your budget
- Skill level and training time
In many shops, a MIG welder may be the most versatile option. But having access to both MIG and stick welding capabilities can give you flexibility for welding a broad range of materials. Consulting with experienced welders can also help provide guidance on choosing welding equipment tailored for your needs.
Multi-Process Welders
Many modern welding machines are designed as multi-process welders capable of supporting multiple welding methods. Some key advantages of multi-process welders include:
- Versatility to handle a wider range of materials and applications
- Ability to switch between MIG, stick, TIG, and flux-cored welding
- Convenience of having several processes in one unit
- Saves space in home shops or garages
Common Multi-Process Welders
Some of the most popular multi-process welders are:
- MIG/Stick: Combine gas metal arc welding and stick welding
- MIG/Stick/TIG: Add TIG capabilities to MIG and stick in one machine
- MIG/Stick/Flux-Cored: Combine MIG, stick, and flux-cored welding
These units allow switching between two or more welding processes on a single power source. Often it just requires changing the torch or electrode holder to change between MIG, stick, TIG, and flux-cored welding.
Benefits
Key advantages of multi-process welders:
- Weld a wide range of metal thicknesses and types
- Use process best suited for each job
- Eliminates need for separate welders

Welder Power Supply and Amperage
Selecting a welder with adequate power supply and amperage output is crucial for high quality welding results. Here are some key considerations when evaluating welder power and amp capacity needs:
Power Supply Types
Common welder power supply options:
- Engine Driven Welders - Gasoline or diesel engines provide electrical power for welding current. Offer complete portability for remote sites.
- Transformer Welders - Step down high incoming voltage to usable welding voltage levels. Lower upfront cost but larger in size.
- Inverter Welders - Use transistors to convert high voltage input to more usable low voltage high amperage output. Smaller size but higher cost.
Amperage Capacity
Higher amperage capacity allows welding thicker materials. Considerations for amperage include:
- Thinner gauges - 60-90 amps
- Medium materials - 100-150 amps
- Thicker materials - 160-250+ amps
- Desired weld penetration
- Material being welded - steel, aluminum, etc.
Amperage directly correlates with the welding arc heat. Insufficient amps can result in poor fusion or shallow weld penetration.
Duty Cycle Rating
The duty cycle indicates how long a welder can operate at its maximum amperage capacity within a 10 minute time period before needing to cool down. For example, a welder with a 60% duty cycle at 150 amps can weld for 6 minutes out of every 10 minutes at that amperage.
Higher duty cycles allow longer periods of continuous welding before pauses for cooldown. This boosts productivity.
Power Efficiency
More power efficient welders like inverter models maximize the usable welding power from the incoming electrical supply. This allows maintaining sufficient amps for quality welds from standard 120V or 240V power sources.
Evaluate power needs based on the intended use case. Portable welders may only require 120-150 amps, while industrial production applications may call for 200 amps or greater capacity.
Choosing the right welder power supply and amperage output prevents frustrating issues like sticking and poor fusion while improving weld quality and productivity.
