Basically pulse is a beginner-friendly welding process that reduce burn through rate and produce batter welding quality.
Pulse MIG welding specially invented for beginners to weld aluminum, stainless steel, nickel, and non-ferrous like materials.
So, you don’t need to take 3/6 month time-consuming training to be a good welder. All you need is just some practice.
There are only a few welders that can take responsibility with pride.
We are introducing here some of the best Pulse MIG Welder from the list.
What is pulse MIG welding?
Pulse MIG welding is an arc welding procedure in which the wire electrode not ever touches the weld puddle.
In Pulse MIG welding,
The fusing power source quickly and automatically switches among a high peak current (confirming good fusion) plus a low background current (drops heat input and decreases distortion).
You can easily recognize a quality machine if you learn the basics of pulse MIG welding.

Considering the need for buying a pulsed MIG welder:
Buying a welder is always a tricky part.
You can’t just go and pick one from thousands.
The factors you should consider before buying a pulse MIG welder are given below:
Welders usually deal with a rough and robust opponent.
So, they should have that kind of caliber to stay strong.
You should look for strongly built welders that can fight for a long time.
Furthermore, they are quite expensive so before buying it you should make sure it won’t give up and will last for a longer time.
Otherwise, you have to spend money on a couple of times for no reason.
Accurate electric outlets installed:
The first thing that you should take into consideration very seriously before buying a pulse MIG welder is the electric outlets.
There are different kinds of power sources available for different types of welders and works.
So, choosing the right power source is important as when you will have the perfect electric outlet installed only then the welder will run smoothly without any disruptions.
Convenient to use:
While you choose a pulse MIG welder to be sure it is easy to operate otherwise you have to suffer and regret later while using it.
Some of the welders are very complex using the method.
So, before you buy the welder you should check that its dial system is not too much complicated and its functions are also adjustable.
The more the welder is user-friendly the greater the outcome will be.
Have you paid heed to the duty cycle while picking up the welder?
If not, you might have a bad time with it.
To make a perfect weld, the welder should have enough strength in it.
If you intend to buy a welder for heavy usage then make sure the duty cycle is at least 60% which means it can run non-stop for 6 minutes.
Regular MIG vs PULSE MIG
The regular MIG welding can be easily explained as joining two materials via a wire electrode that is solid and constant, while the gas passes through the gun.
This is the older, classic MIG welding technique.
Pulsed MIG is a type of classic MIG welding.
What is the key difference?
As you probably assume, the current of the pulse MIG welding is - pulsed.
It originated from the need to control the transfer of metal when it comes to low current.
Pulse transfer is primarily a kind of spray.
The arc is open, but instead of the axially small droplet current, the machine electronics control the axial firing of each drop separately or of a couple of drops per unit of time.
The size and velocity of a drop are also controlled.
In addition, the electronics control the period of time after which the next drop of wire is separated from the wire.
We’re not through yet...
Some sources say that the electronic experts must set 64 control parameters.
That’s why this technology is not done manually for decades.
This means that each parameter is not set in a separate way.
Instead, the so-called "synergic pulse lines" were designed.
What does this actually mean?
The user simply informs the machine on the type of the gas chosen, as well as the wire material, the diameter and chooses the material thickness.
Then, the computer calculates all the parameters (the above-mentioned 64 different control features) and gives you the result.
It gets better!
Pulse is an outstanding method of welding of the non-ferrous metals and stainless steel.
Therefore, it is the very first choice among them all.
Every expert will tell you that this is a supreme method of welding.
Pulse welding uses gases that develop spray transfer. For steel, Ar + 18% CO2 is used.
Also, you can choose Ar + 8% CO2 is the best option. For stainless steel, you should use Ar + 2.5% CO2. For aluminum, pure argon is the best option.
Once again, we want to point out that spray and pulse are not possible with pure CO2 gas.
High-speed pulse is a type of pulse MIG welding. We have already said that electronics control the separation of the drop in the unit of time in the classic pulse MIG welding mode.
The high-speed pulse implies control of a few drops (e.g. 3 drops) in the unit of time.
Benefits of pulse MIG welding
Benefits of pulse MIG welding include:
- Significantly less or no spatter (when compared to other types of welding).
- Welding at 50-150 A current is possible.
- Pulsing extends the 180-220 A spray operation.
- Pulsing is the perfect choice for thick sections.
- Working at higher deposition rates is possible thanks to the pulse.
- Good even for jobs where spray transfer is not possible.
Pulse MIG welding settings
Knowing how to adjust the speed of the wire and the voltage is of the utmost importance when working with pulse MIG welders.
Some machines will resolve these issues by themselves based on pre-determined settings. However, it is good to know the basics.
In addition, you must know some transfer settings too. There is a new standard on welding attestation, the ISO 9606-1.
It specifies the transfers in detail. "Transfer" is the way to transfer a molten drop from the wire across the port into the molten metal of the object to be welded.
Why is this important?
It is important because this standard refers to the pulse MIG welding as a type of transfer spray.
Therefore, we strongly recommend you to refer to the ISO 9606-1 standard to learn more about the specific settings and procedures.
When it comes to the hot start feature setting, there are a few parameters you should pay attention to. Those are:
- The setting of the time period (duration)
- Percentage of how much the initial amplitude is higher than the one determined by the wire speed and overhang.
For example, you can choose the following setting, during the first second, the amplitude is 40% higher than the one resulting from the pre-set wire speed and overhang.
Why is this important? It is sometimes difficult to obtain an impermeable welding result.
Therefore, we choose the higher current than the pre-set one during the first 1-2 seconds. Then, the amperage returns by itself to the pre-set value.
So What's The Verdict...
Pulse MIG welding has been used in industrialized production for about 20 years, breaking into the handheld marketplace no more than years ago; it can be used for numerous things.
But to achieve a fast better outcome welding the stainless steel and aluminum, you have to choose the compatible welder very cleverly.
