The Orion mPulse­­®

The mPulse power settings range from 3.0ws to 30ws, in 1ws increments-that's 27 different power settings to choose from. The weld spot size on the smallest setting is nearly 1mm, depending upon your material. The largest setting of 30ws will yield a weld spot approximately 1.5mm in diameter, again, depending upon the material you're welding.

The mPulse works amazingly well with Gold, Silver and many other metals. It's a superior alternative to any solder application; and, measuring in at 25x30x40 cm, the mPulse takes up almost no space on your bench.

Our customers use the mPulse 30 for a variety of applications. Many glass frame repair shops can now fix broken titanium frames. Small scratches are easily smoothed over with wire and a round of welds from the mPulse. Any small metal application gets easier to work with when the Sunstone Orion mPulse welder is on the job.

How can such a small thermocouple welder machine do so much? We continually perfect and improve the welding technology put into the products we've been making for more than 10 years. Tailored to the needs of our clients, each Orion Pulse Arc Welder is a demonstration of why our products exceed the competition through research and development from our Ph.D. team of engineers.

How Does it Work?

Electrical Energy - Plasma Discharge

Micro TIG/Pulse Arc welding uses electrical energy to create a plasma discharge. The high-temperature plasma, in turn, melts metal in a small spot. This process takes place in milliseconds. The process is clean and very controllable - perfect for intricate and minute welding applications on precious and non-precious metals!. Filler metal can also be added to build up joints and create strong and reliable weld "beads", or weld seams.

The Basic Principle of the Orion Welding System is very simple.

1.) Attach The Grounding Clip

2.) Use the Specialized Microscope that is focused on the Welding Electrode Tip.

3.) Simply Touch the workpiece to the electrode and a weld is triggered.

4.) A Perfect Weld Every Time!
