Best Micro TIG and Pulse Arc Welders

Our Best-Selling Micro TIG / Pulse Arc Welder Products

Before we get started with our most popular products, you need to understand the concept behind these first. Get to know what TIG welding and pulse arc welding are, as well as what they’re used for, by reading on.

What is TIG welding?

Gas tungsten arc welding is also known as tungsten inert gas welding. It is an arc welding process that uses a dense, non-consumable tungsten electrode to produce a weld. As its name suggests, this process uses an inert gas, typically argon, to protect and cool the weld puddle.

What is TIG welding used for?

Now that we know what TIG welding is, let’s find out what we use it for. TIG welding offers higher precision and control than most welding processes and is used in a variety of industries where a certain level of control is necessary, such as:

1.    Aerospace – Aircraft and spacecraft components are typically constructed using TIG welding. These include commercial planes that people fly on as well as the sophisticated International Space Station and the rugged space shuttles that the National Aeronautics and Aerospace Administration use. All of these have benefitted from the strength and precision of TIG welding techniques.

2.    Automotive – Safety and Security are the primary concerns in the auto industry. Again, strength and precision that the TIG welding process offers in invaluable for carmakers around the world. In motorsports, TIG welding once again is used for fabrication of race cars – by keeping things light and durable, being able to withstand crashes and keep drivers safe.

3.    Repairs – Smaller businesses that are staffed by skilled welders often use this process. With TIG welders, they fix smaller, more complex workpieces such as a child’s toy, a piece of furniture, or household metalwork.

4.    Art and Jewelry – The level of control and precision that TIG welding offers is unparalleled compared to other welding processes. For this reason, TIG welding is used for crafting complex objects of varying sizes, shapes, and metals to produce great works of art. In jewelry, it is often used for crafting and repairing metals such as those found in rings, necklaces, bracelets, and so on.

What is a Pulse Arc Welder?

So how is a pulse arc welder connected to a TIG welder? Simple. Pulse arc welders are micro TIG welders.

A pulse arc welder makes use of a non-contact method involving electrical energy to produce high-quality welds. You don’t need to apply force. All you need is a non-consumable tungsten electrode, which some pulse arc welders usually feature as a sharpened tip. With the pulse arc welder, an arc is generated between the tungsten electrode and workpiece, as the name suggests. The generated arc creates a high-temperature plasma that can melt metal.

Pulse arc welding is a high precision, TIG type, plasma discharge, welding process.  Sunstone Engineering’s pulse arc welders are capable of extremely precise energy discharge.  Each plasma discharge creates small laser-like welds.  Pulse arc welding, like laser welding, is typically an edge welding process.  The weld spot is created as the tungsten electrode is withdrawn from the weld surface and the melting process starts from the outside and penetrates inwardly.  Like traditional TIG welding, pulse arc welding can be used to add additional material, like fill wire.  This is useful in many applications where additional material is needed for additional strength.  Additionally, pulse arc welding can also be used to melt and fuse to parts together without the need for fill wire.  Unlike traditional large-scale TIG welding, pulse arc welding can create welds that bridge gaps between parts. This is due in part to the high peak weld currents and liquid metal dynamics that occur during the short welding process.

An additional advantage of pulse arc welding is the extremely low energy input to create the weld.  This welding property means that even heat sensitive parts or pieces can be welded with very low chance of thermal damage.  Pulse arc welding also helps reduce any distortion that would typically happen during other welding processes.
Pulse arc welding is a versatile and economical welding process for a variety of applications.  Sunstone is happy to help you weld your application or to help you bring pulse arc welding in-house to your facility.  Contact us to see which solution will be the best for your business.

How do you use a Pulse Arc Welder?

Pulse arc welders are great to use on copper, platinum, titanium, stainless steel, silver, and gold. It makes welding a lot more efficient, clean, and controllable, especially when it comes to tasks like repairing castings and sizing rings. You can even use a pulse arc welder on more complicated jobs, like welding dissimilar metals together.

Because of how solid and robust the welds created with pulse arc welders are, the following industries utilize it for their welding needs:

  1. Optics
  2. Mold and Die
  3. Dental
  4. Jewelry
  5. Research and development

Pulse arc welders are a top-rated product of ours, but the following are ones that our clients frequently buy.

1.    The Orion mPulse 30 Pulse Arc Welding System

The Orion mPulse 30 Pulse Arc Welding System is particularly suited for light repair work and jewelry. With a 30ws power potential, this thermocouple welder can be used by almost anyone and has the power to tackle all sorts of jobs. It’s the perfect tool for hobbyists and beginners with its compact size and easy-to-use touchscreen user interface.

Power settings range from 3.0ws to 30ws, in 1ws increments, making a total of 27 different power settings to choose from. Spot weld sizes vary from 1mm to 1.5mm depending on the material of the workpiece and power setting that you selected.

The Orion mPulse 30 is the ideal tool for working with gold, silver, and many other metals used in jewelry crafting and repair. Other fragile items such as metal glass frames can now be fixed using the Orion mPulse 30. This makes it a great addition to any eyeglass repair shop. The design is such that it allows the operator to use the mPulse 30 using both hands, for more precision. The built-in touchscreen LCD user interface also makes it easy to select the right power setting on the fly, without having to fiddle with primitive knobs or buttons.
