Pulse Welding: A Beginners Guide

There have been many questions regarding pulse welding. Many of you are asking:

Why would you pulse weld as opposed to weld without pulse?
How do you determine how many pulses per minute to use?
Do all machines have pulse welding capabilities?
In this episode, Wyatt answers these questions. He also goes into some demonstrations of different pulse settings, including 1 pulse per second, 10 pulses per second and 500 pulses per second.

The Setup:
When setting up your machine for pulse welding, there are many different aspects you can set. For the purposes of this video, Wyatt set the machine for 50% background (low end amperage) at 30 amps 50% on time (high end amperage) at 120 amps for each demonstration. The difference in setup comes into play in the amount of pulses per second that he used. You will see four demos:

No Pulsing
1 Pulse per Second
10 Pulses per Second
500 Pulses per Second

NOTE: The clear cup is used for better filming purposes. It is not required for pulse welding.

There are many ways to set up pulsing, but I prefer to have a constant travel speed.

Thanks for the question.

"I dont use tig very often, but when I do..." haha HE IS the most interesting welder in the world! Another great video, keep em comin.

[garyhoward]

Would you agree that pulsing can also help a beginner by moving slower hence maintaining more control, e.g. at a pulse every 2 seconds?

[hondafreak]

Thanks for going over pulse and benefits. Was in the fence about getting tig with pulser. Definitely am now. Will be definitely welding rusty metal from new england.

I used an INVERTEC similar to yours once, and could not work out the how to make it pulse even with the instruction booklet. Too bad i don't use it anymore this would have been helpfull. Good stuff. You are one chilled out dude.

[johnadams]

It would have been VERY helpfull had you shown the welds up close so as to be able to tell the difference between the settings.

[turbotrana]

Like these videos where you actually show welding and explain stuff

0:34. "I dont pulse weld often. But when i do, prefer DOS equis....TIG DC my friends...."

[noup]

are you moving continuously? My instructor told me to pause on the on and move when its off or low...

[javiergarcia]

When your welding in outer space there is no gravity. In fact no gravity any where around you. Weld puddle is everywhere. That's why I usually set it to nongravity quantumatic emp mode.

Hallo Mr Tig,
Please tell me for what kind of metals is it good to use Pulsed Tig, and at what setting should I place the Pulse duration ratio, and pulse frequency whethat I have to set in Pulse Tig mode.

[polimecanos]

Hi Mr. TIG, would you make a video reviewing TIG Cold Welding, I can't trust anyone else !!!!

[kw]

What (% ratio pulse amps) do I put my everlast 250ex on when welding 18ga ss?? Any idea? I noticed you never mention in your videos this setting

[mrjp]

now I have followed several who show their machines at 220v / 50Hz. But what are the advantages of a machine that is at 400v. which companies use when in all only shows 220v. tik. welder. I stand to have to buy my first machine. I live in Denmark.

[johanbekker]

What settings can I use to fuse 1mm or 1.6 mm pie cuts without filler rods

[scottdavidson]

Get your welds in focus, otherwise you’re just demonstrating what the machines can do and not showing the results.

[ericrepass]

Does dabbing with 1 pulse per second help make flat rig weld beads?
