Why Choose A Pulse-Arc Welder?

A pulse-arc welder consists of a negative-charged tungsten electrode and a positive-charged grounding clip. The workpiece is connected to the positive-charged clip.

The key advantages and unique features of pulse-arc welding are:

  • Welding on conductive metals such as Silver and Copper
  • Deeper and stronger weld penetration
  • Lower initial investment costs
  • Cheaper maintenance than other welders
  • Smaller in size

Premium Argon Gas From Sunstone

Premium Argon gas is now available for delivery right to your door! Convenient right-sized tanks delivered right to your door by UPS. Sunstone will also include free return shipping on empty tanks when you order a replacement tank.

This premium argon prevents oxidation, providing you with cleaner welders. We ensure the safety of these tanks with steel safety caps for more secured shipping.

Not only are these new Argon tanks easier to move than larger tanks, but at only 30" tall, they are small enough to fit under most workbenches. Out of sight, out of mind.
