• •  Additional education on using a mini welder is often included in hardware engineering classes at many colleges and trade schools. In addition, some companies teach miniature welding through on-the-job training.

Miniature and portable welders come in a wide range of sizes and capabilities. Most portable welders are large machines designed for industrial use, equipped with wheels or portable casing for easy mobility.

A miniature welder, on the other hand, may be smaller and handheld. A mini welder is ideal for joining thermoplastics or small spot welding projects.

When searching for miniature and portable welders, consider all the following:

1. Look for portable welders on wheels and in mobile casing for industrial machinery.
2. Browse welder-generators for a portable power source in addition to welder mobility.
3. Look at handheld welders if you want a mini welder or micro welder.

Browse portable welders for sale with wheels and easy to transport casing

Most portable welders designed for industrial use (including MIG and TIG welders) will function just like a traditional welder, but will come in an easy-to-carry welding kit. These portable welders are easy to pack away and carry with you, and cases are heavy duty plastic to withstand industrial wear and tear.

I recommend: Ready Welder and RD both sell portable welders in heavy duty plastic casing. The Ready Welder model is a welding kit that comes in an easy to carry case, while the RD models are larger and more accurately described as a portable welding box.

Browse portable welders for sale with a portable power source

Not all portable welders come equipped to have portable power as well. If you want to look at portable welding machines that don't require long cords to operate, check out a welder/generator. These welders are typically larger and bulkier than a mini portable welder, but also come with mobility features like wheels and durable casing.

I recommend: Arcon Welding sells constant power welding machines, and ETQ Power Generators sells a combination generator and welder. Powered portable welders are a great alternative to other miniature and portable welders if you are more concerned with a portable power source than a welder that is light and easy to carry.

Shop for both miniature and portable welders

A mini welder doesn't offer the same power capabilities as a larger welder equipped with portability features, but miniature welding machines can be a great choice if you need an easy to transport welder for spot welding jobs. Shop for both mini and micro welders if you want a handheld welder for spot welding.

I recommend: Grizzly sells a mini welder that operates much like a traditional welder on a smaller scale. If you want a more handheld model, try Sonics for equipment good for working with thermoplastics and other spot welding jobs.

• •  Consider the uses for your welder before buying a miniature welder or a portable generator/welder. Both types of welder are useful for certain purposes, and you may even want to have both in your stock of machinery depending on what types of welding you do.

Miniature and portable welders are useful devices for welding smaller industrial components. You can easily carry these tools from one place to another, unlike bulky industrial welding machines. Portable welders are available with wheels that assist in easy mobility. Miniature welders are convenient in small-spot welding jobs.

If you want to use miniature or portable welders in your business applications, you need to be familiar with the industry jargon. This guide will acquaint you with certain key terms, such as mini-weld guns, stick welding, MIG welding, TIG welding and spot welding.

Mini-weld guns

A mini-weld gun is lightweight and useful in light duty projection and resistance welding. You can use these guns for welding small appliances and electronic components.

I recommend: Get useful information on mini-weld guns at Hanson Systems, a division of Welding & Automation.

Stick welding

Stick welders are manual arc welding tools that derive heat for welding from an electric arc. This type of welding is also known as SMAW (Shielded Metal Arc Welding) process.

I recommend: You can read through the fundamentals of stick welding at The Lincoln Electric Company, a manufacturer of welding products.

MIG welding

MIG (Metal Inert Gas) welding is also known as wire-feed welding and GMAW (Gas Metal Arc Welding). MIG welding is useful in commercial fabrication settings that require continuous welding. Mini MIG welders are very popular in the welding industry.

I recommend: For more information about the MIG welding process, read through the description at Rod Ovens.com, a supplier of welding ovens.

TIG welding

In TIG (Tungsten Inert Gas) welding, a tungsten electrode heats the metal to be welded; the gas then protects the welded piece from air contaminants.

I recommend: To understand the basics of TIG welding, read through the description at Miller Electric, a manufacturer of welding equipment.

Spot welding

Spot welds are made on overlapping pieces of metal parts. Spot welding creates precise bonds by applying electric current and pressure.

I recommend: To learn more about spot welding, you can read through the information at Softpedia, a useful online resource.

Welding torches

A welding torch is a portable light device that allows control of the flow of gases per requirements. It mixes the gas and fuel internally and produces a hot flame. Welding torches have applications in gas welding and torch brazing processes.

I recommend: At Engineers Edge, a useful technical resource, you can find the definition of a welding torch.

Miniature and portable welders are ideal for use in numerous industries. The price for the welding equipment depends largely on the functions of the machine. For example, a portable welder used for plastic is usually more expensive than miniature welders used for welding metal.

Miniature and portable welder pricing and costs don't stop with the purchase of the machine. You have to also prepare your budget for the long term costs of the machines. Consider the following points to help you prepare your budget:

1. Purchase a miniature welder for small jobs or jobs in really small spaces.

2. Upgrade to portable welders for larger jobs, even if the job is in a tight spot.

3. Prepare your budget for recurring costs of welding accessories.

Consider a miniature welder

A miniature welder is ideal for welding in tight spots. However, these models are less than ideal if you are going to be welding large areas. The price you pay for miniature welders depends on the features and specifications you need. For example, a temperature control option will make your welder more expensive than a model with only one temperature option.

I recommend: Burke Tools sells a varied selection of mini welder models. Prices start just under $400 for these models. Tool Outfitters offers a miniature welding machine priced at under $200 that is suitable for welding plastic.

Invest in portable welders

A portable welder is larger than a miniature welder. Portable welders are also suitable for welding in tight spaces and they are also better for welding large areas. The price you pay for these welders depends on the power source, as well as the welding functions offered.

I recommend: You can find portable MIG welders and portable TIG welders at Weldfabulous. Prices vary according to the model; however, you can expect to pay anywhere from $500 to $8,000. Drill Spot has portable welders for sale. Prices range from $200 to $2,000.

Remember to include the cost of accessories for portable welders

Accessories for portable welders include weld tips and welding guns. These items have limited uses. As such, you must prepare room in your budget to replace these items on a regular basis. The price you pay for these items is dependent upon the model of miniature or portable welder you own. Another factor that affects the price you will pay is the function of the accessory.

I recommend: Harris Welding Supplies sells a variety of welding supplies, including welding guns. The selection of welding guns starts at under $150. You can find welding tips at Handheld Items. Prices start at under $5 and go up higher than $350.
