This particular welder by Miller electronic has combined sophisticated inverter engineering with Auto-Line technology.
This means that functionally, it's probably the most flexible AC/DC TIG/Stick power source across most welding options that you will see.
Well, because it’s able to achieve a top voltage of 460 volts.
Additionally, it possesses a unique feature known as the SquareWave Arc that is responsible for better “weldability” on magnesium and aluminum.

Hazards When Welding
Protection is a crucial thing to consider whenever welding.
Arc welding can be safe to do when the right precautions are taken.
Nevertheless, in case safety procedures are ignored, welders can come up against an array of risks which may be potentially dangerous, which includes electrical shock, fumes & gases, explosions, and fire among other things.
Electric shock is realistically among the most pertinent risks facing a welder. Electrical shock can result in serious injury or maybe death, both from the shock itself or perhaps from a fall brought on by the response to a shock.
Electric shock happens when welders come in contact with two metal objects which share a voltage, thus inserting themselves into the circuit.
For example, in case a worker holds a blank wire in a single hand along with a second blank wire with another, electrical current will pass through that wire and throughout the welding operator, causing an electrical shock.
The bigger the voltage, the taller the present. This increases the danger for the electrical shock to end up in death or damage.
Shock from Secondary Voltage
Probably the most frequent kind of shock is actually secondary voltage as a result of an arc welding circuit, ranging from twenty to a hundred volts.
Remember that actually, a shock of fifty volts or perhaps less can easily be sufficient to injure or even kill an operator, based on the conditions.
As a result of the frequent change of polarity, AC (alternating current) voltage has a higher chance of stopping the heart than direct present (DC) welders.
Ways to Prevent Shock
In order to stay away from this type of shock, operators must make sure to use dry gloves in a suitable condition. Do not make contact with the electrode or the metallic parts of it with wet clothes or skin.
You'll also want to insulate from the job as well as the ground, maintaining dry insulation in between the body and also metal that is welded or ground (such as a metal flooring or maybe a wet surface).
Welding operators must also make sure to examine the electrode holder for harm before starting to weld and keep the welding cable as well as electrode holder in perfect condition. If this is not followed, the plastic/fiber insulation on the electrode holder stops communicating properly with the components inside.
Always make sure to fix or even replace broken insulation before use. And don't forget, stick electrodes are usually hot, even when welding isn't being carried out and the voltage is more than likely the highest.
Fumes and Gases
Welding fumes can have potentially dangerous complicated metal oxide compounds from consumables, base metallic, as well as the base metal coatings.
Therefore, it is essential to keep out of the fumes by buying adequate ventilation. Having exhaust options is also necessary to manage the exposure to substances based on the rod type and base metal being used.
Welding areas need local exhaust and enough ventilation to maintain fumes and gases from the breathing zone.
Safety in the Workplace
In the majority of cases, employers may provide a ventilation system like a fan, or an exhaust system. Whether removable or fixed, exhaust hoods are meant to eliminate fumes and gases from the work region.
Welding operators really should use a certified respirator, except in the case that exposure assessments are below appropriate exposure limits.
Industrial hygienists take air samples in the worker's breathing zone to figure out whether a worker's exposure is sufficiently low enough.
In case the atmosphere in the breathing zone is not clear, or in case breathing has become uncomfortable, check to make sure the ventilation equipment is operating correctly. Report any concerns to a supervisor so your exposure to substances from the welding fumes may be examined.
This is particularly crucial when welding with stainless steel or even hard facing products. In order to stop exposure from coatings like paint, galvanizing, or maybe metallic platings on base metals, clear the base metal before starting to weld. See a physician in case problems from overexposure persist.
Fires and Explosions
The welding arc produces extreme temperatures, which could also be the cause of a major fire/explosions hazard if appropriate methods aren't followed.
Even though the welding arc might achieve temperatures of 10,000 degrees Fahrenheit, the true danger isn't from the arc itself, but intense heat as well as the arc, sparks and spatter produced by the arc. This spatter is able to jump to as much as thirty-five feet from the welding space.
Examine the vicinity
In order to prevent fires, before starting to weld, examine the work location for any flammable substances and eliminate them from the area.
Flammable materials are actually made up of 3 categories: liquid, like fuel, paint, and oil; solid, for example, wood, paper, and cardboard; and gas, such as hydrogen, propane, and acetylene.
Make sure the alarms and extinguisher are kept in check.
In case an extinguisher isn't available, make sure you have access to fire hoses, some other gear or maybe sand buckets that are able to douse the fire. Be aware of the location of the nearest fire exit too.
In case of welding within thirty-five feet of flammable substances, have a fire watcher near you to keep monitor of sparks, as well as making sure to stay in the work area for no less than thirty minutes after finishing welding to be certain there aren't any smoldering fires.
Fireproof your place and don’t panic!
Put fireproofing, like a slice of sheet metal or maybe a fireproof blanket, over any flammable substances within the work area, in case you cannot eliminate them.
In an elevated area, ensure no flammable materials are actually beneath you. Look out for other employees below you to avoid dropping sparks or that you spatter on them.
Often high concentrations of fine dust particles might result in explosions or sometimes flash fires.
In case a fire starts, do not panic - call the fire department immediately.
Injuries from Inadequate PPE
Personal protective equipment (PPE) can help keep welding operators totally free from damage, like burns - the most typical welding injuries - and exposure to arc rays.
The proper PPE allows for freedom of movement while still offering sufficient shelter from welding hazards.
This is because synthetic material like rayon and polyester will melt when subjected to excessive heat. Welding leathers are specifically suggested when welding out of position, such as when overhead or vertical welding is required.
Our Miller Dynasty 200 Verdict
The Miller Dynasty 200 costs a bit more than the majority of the others on the market. However, the moment you use it, you will better understand why. It's extremely useful and delivers what it's meant to.
Plus, it’s so easy to use and has a sizable selection of extra functions which give it much more worth. The AC/DC capability would mean that it may be utilized with a range of metals, rendering it practical and versatile.
Consumer views raise the bar when it comes to this welder since they’re generally good. Some complaints are only around the visual appeal of the item rather than its seemingly flawless functionality.
When searching for a good quality welder, which packs an effective punch, look no more as opposed to the Dynasty 200. You won't regret it.
