Faster TIG Speeds
Increase TIG Welding Speeds.
As owner of a welding company in California, my profession is welding, and I enjoy the success I’ve achieved over the years. But, I really like to spend my time fishing. That’s why I have changed my TIG welding process to a pulsed-TIG process for most of my TIG projects. By using pulsed-TIG, I can increase my production by 50% - I get my work done in half the time and spend more time fishing.
Previously, with the TIG process I could weld a 2-in. ground pipe at 45 – 50 amps. Now with pulsed-TIG, I can weld that same piece at 90 – 100 amps. I put my work on a rotator, set my pulser, and my weld ends up looking like it was welded by a machine. With pulsed-TIG you can increase the heat, weld faster, and have better control of the bead size.
It’s also a huge benefit when welding out-of-position. For example, when I go from a flat weld to an uphill weld or overhead weld, typically you have to slow down your weld speed, the weld width is minimized, etc. But, with pulsed-TIG the weld doesn’t sag, I can maintain my heat and speed, and finish with a high quality TIG weld.
The concerns I’ve heard from fellow welders, is that it’s hard to set a pulse-TIG machine. Many welders don’t have the background to simply set their machines for this process and it scares them away. My answer is to learn it – it could double your production and make you more money. I also think the educational facilities could use welding manufacturers as more of a resource to stay on top of welding process trends and learn the pulsed processes, so they can effectively teach it to students upfront.

what welding mach are you using? I have a dynasty 200 and 300 but have used the pulser very little. thanks

Hi Ed, unfortunately Tony is on a month-long fishing trip and won’t be able to check his email, but I know that he uses his Dynasty 200. Try out the pulser and let us know how it works for you.
Thanks!

The majority of the work our company does is sch10 - sch80 304L SS pipe 2″-12″. We walk the cup 100% of the time. Amperage range is from 60 - 95. I am assuming that you are not walking the cup and free handing your welds. I have a hard time beliving that you can acheive the same consistancy free handing as one would with walking the cup. We do do not use weld positioners, therefore every position is seen while welding our pipes. I would like to know what you would use for weld parameters, as an example, for welding 6″ sch 10 304L SS pipe. I am always open to sugestions to improving weld speed, and quality. Thank you BR

BR, that's a tough one. For my welds I'm not out in the field, so I can run rotators with a fixture and eliminate human error. I am not walking the cup, and as far as I know, you can't pulse and walk the cup. You can give me a call and we can talk some more about your application and see if I can give you some suggestions. Thanks for your comment. Tony (805) 235-0729

Hi Iam into pulse tig welding and use the pulser very often.I asked one of the welders to pulse the machine old school style or set up the machine.According to the other guy.he claims that pulse tig welding is for beginners and that advanced tig welding you should be able to set the machine at high amps and move the torch quickly across the joint and push the rod into the puddle in one motion. No dipping.I beg to differ.what do you think is going thru the mind of this welder.Uneducated or correct in thinking that pulse tig welding is for beginners welders in general when learing to tig weld

Hello marlo. Yes you are correct.Pulse tig welding is a very advanced form of tig welding.Even if you were to show a beginner.There is no way that he would pick up the motion when the machine is set at a low pace.Understanding of heat, puddle manipulation, penetration ,along with coordination and speed and extreme dextertiy of the hand eye and foot all need to come into play.A beginner could not even grasp two of these method without years of expertise.Sounds to me like the welders you are referring to are just production welders who care less about the quality of the weld .They probably do not even know how to pulse properly regular or machine set up.If they did know.Flat out they would know pulsing is way faster regardless how many years of expertise they have. Without seeing the other welders weld work.I can bet that their welds have a high crown which uses twice as much rod and could not pass a good looks test

In response to Marlo and Lane.Both have very good points and is really hard to say without really looking at the whole situation in person.What I can say is that .You can show a beginner how to dip into the puddle but that is it.There are way more effictive ways to show a beginner.By showing the beginner with the pulse method .You will confuse the beginner because you have to gear the settings to the welder.Now you have to explain how all the settings work so that he can tailor the settings.For example if the settings are welding way to hot.The beginner welder will be concentrating on not putting holes in material rather than learning to dip.Pulsing with a sequencer are all advanced.I best believe that basic teaching and learning to oxy acty first will give the beginner strong skills and can later learn pulse tig welding when they are ready.But yes as lane said Pulsing is the fastest method because you can throw a lot of heat into the material not ruin it and have high quality welds.People who have literally mastered tig welding more often than not pulse tig whether manually or machine set.setting a Machine does require an extreme understanding of ac/dc currents puddle manipulation etc.There are few Tiggers who have the knowledge because most have learned on the job .When on the Job. It is not the companies responsibilities to teach electricial working of TIG but merely whether the welder can TIG weld and if they been doing welding for several year it is probably good enough for the company

Hello,
I was wondering if anyone could help me out on settings for Pulse welding. We have a history of Pulse welding in the vertical and horizontal positions. I am wondering what settings I should use for Overhead welding of HY-100 material that 1″ thick. I need somewhere to start.
Thanks
