You should also know their response time and ensure spare parts and consumables are available. However, note that high-quality consumables will ensure a longer life cycle. Hence significantly reducing the maintenance cost in the long run. 

Always use genuine manufacturer’s consumables since they are cost-effective and safe. Additionally, check the warranty process before making the final purchase decision. 

3. Price 

The price is important because it dictates the type of welder you’ll buy. Price is money, but this shouldn’t be the case when purchasing a welding machine. The welder’s price should stand for quality, reliability, service life, serviceability, etc. 

Use your money to buy a reliable machine. The Miller Multimatic welder machine is expensive but will offer you back value for your money. That’s because it’s long-lasting and high-quality. 

There are many other cheap Miller Multimatic models, but their quality isn’t impeccable. Overall, whatever welding situations or needs, Miller Multimatic 215 will work well for you. 

4. Welding Machine Usage 

Is the welding machine for personal or shared use? The end user’s opinion is crucial when making the purchase decision. 

Brand loyalty comes into play if the welding machine serves an individual user. You can pick a welder from your most trusted brand, like Miller Electric. 

But, if the welder serves several users, you’ll have to consider the interface, language options, durability, etc. In industrial settings, purchasing a welder depends on experimentation and demonstrations. 

Here the welders familiarize themselves with the machine features. If they like and easily understand the features of a particular machine, then you can buy it. 

The salespersons should guide you through the welder’s features and offer enough trial periods. You can also get more information about the welding machine from other users. 

5. Welding Location 

The location for your welding work should help you decide on how to choose a suitable welder. Pick a machine that operates at 150 volt AC or 220-240 volt AC supply for indoor welding. 

Generally, most welding machines operate at 115V. It’s also the normal supply that most domestic and commercial places receive. 

6. Power Supply Requirements 

Welding machines use AC and DC power inputs and outputs. AC power supply is cost-effective and easy to handle but has low thermal efficiency. In addition, AC is also more popular than DC. 

However, AC is not ideal for non-ferrous alloys and metals but is great for iron group metals. AC has difficulty beginning arc, making it less capable for welding metal sheets. It’s the most preferred power supply for TIG welding. 

On the other hand, MIG welders use a DC power source. The DC power supply offers a steady voltage for welding. 

Amazingly the Miller Multimatic 215 uses both AC and DC power supplies. Therefore the machine will cater well to all your needs. 

Type Of Welding 

There are different types of welding which include: 

MIG Welding

It’s the most popular welding type since it costs less. MIG welding is also easy to learn and capable of handling various projects. In this welding process, the welder can steadily hold the torch with both hands, unlike in TIG. 

It also has an incredible wire feed speed that makes it four times quicker.

TIG Welding

You’ll surely appreciate TIG welding after completing your project. TIG welding produces high-quality and clean welds. 

TIG also eliminates splattering because it only uses the required amount of filler metal in the weld puddle. Therefore ensuring you have a high-quality weld.

Stick Welding

According to professionals, it’s the most effective welding technique for connecting alloys and joints. 

However, it’s the least efficient type of welding. In this welding process, you’ll need a consumable rod electrode. 

The rod works anywhere, whether outside or inside, and the process is easy. The weld seam doesn’t use shielding gas protection, but electrodes have a flux coat that protects the weld. After welding, you have to remove this layer. 

Stick welding doesn’t use the shielding gas, making it a popular and economical choice. 

Welding Machine Feature and Specifications 

You should check out the welding machine’s features and system specifications. You’ll be able to know some key elements of the machine that’ll prove vital when choosing it. 

For instance, the machine’s specifications will help you understand how long you can use the machine. 

You’ll also learn about duty intervals and weld you can carry out in standard intervals of 10 minutes. 

Therefore you should properly understand various variables like duty cycle. If you exceed some, you’ll be damaging the system’s circulation. 


The amperage is another important factor to consider when choosing a welding machine. It determines the type/ nature of jobs the welding machine can handle. There is a huge amperage difference when working on various metal thicknesses. 

As a welder, you should understand what works well for you and the flexibility you want from a welding machine. 

Welding Positions You Anticipate 

Most arc welding operations happen on a workbench with the workpiece lying horizontal and flat. 

However, there are instances when this orientation isn’t feasible. It’s usually referred to as “out of position welding.” 

In addition, some jobs happen onsite and in less ideal conditions. For instance, there are times when you’ll have to perform vertical or overhead welding. 

Here flux-cored is the best welding process since it utilizes a continuously fed wire with flux in the electrode. 

You can use other arc welding methods for out-of-position welding. However, they’ll have some challenges and limitations. 

It’s the setup that is usually tricky. For MIG and TIG welding, the shielding gas cylinder must be near the workspace for hooking up to the machine. Therefore this could impede out-of-position welding.
