Three Reasons to Invest in Pulse

You can't go far in the welding circles without hearing about pulse these days. With the emregence of #weldporn and the Instagram revolution, people are becoming more and more fascinated by pulse welding. Manufacturers are pushing the addition of pulse features on their machines and consumers are buying. 

So what is pulse? Simply put, pulse welding alternates amperage from a peak setting to a background setting at set intervals. For example, if you set your machine at 100 amps and 1 pulse per second with a background current of 50%; your machine will go from 100 amps to 50 amps and back to 100 amps every second. 

The truth is, pulse welding isn’t needed in most instances, so why buy in?

Whether you are selling commissioned artwork or aluminum trailers, customers care about weld aesthetics. Pulse welding is one way you can achieve a very uniform “stacked dimes” look to your weld. The method is often used when welding bike frames and tuna towers to acheive beautiful, consistent welds.

2. Heat Control:
One of the major advantages to TIG welding is the ability to have very fine control over heat
 input. Pulse welding gives welders even more control over the puddle by allowing them to put less heat into the work piece, while still achieving proper fusion. This is why pulse is often used when welding extremely thin materials and edges. We did a video back in January of 2013, called “TIG Welding Stainless Steel Corner Joints”, where we showed the difference between pulse and no pulse on a corner joint.

3. Welding Out of Position:
Another advantage to pulse welding is that it allows your puddle to freeze faster. This is particularly advantageous when you are welding out of position. By pulsing, you can keep your puddle in the joint, leading to better penetration and weld performance.

So the question remains, is pulse worth the investment? With inverter technology making power sources more affordable every day, the answer is a resounding, YES!. You never know when your next job is going to require you to have just a little more control over the weld pool and you'll wish you had it.
