View Full Version : Pulser settings......
I have made parts in the past for the semi-conductor industry that incorporated
the pulser mode on a tig welder. It seems that no two machines are the same
when it comes to the "PULSER SETTINGS" I don't know if it's because the machines are in better shape or the pulser gadget is screwed up...The question is how does a guy know where to start? I usually take a part that was scraped
and practice on it, but you don't always have that convenience.....
So Tig welders of the world talk to me.....How do you do it?
Shaky Hands, BC LOL

These are throttle shafts for a local company that builds on board computers for bracket drag racing I built their shafts for years till they sold the company
to a back east shop....The name of the company was DEDENBEAR PRODUCTS

Talk about some seriously repetitive welding...
they should get a robotic welding solution of some kind.
I wasn't saying anything negative about the welds, they look fine.
When I discovered this site it was from my Google on straight DC aluminum...
I picked some brains and then read some of the posts......It was pretty good reading and I found myself getting involved with HELPING others.....But
I am by far the smartest guy around and I try to learn something new as often as I can. All the welders I have ever met have this EGO thing going....
Some show it more than others....As far as the comments on my welds or
my techniques......Hey I'm always OPEN for suggestions. If you can make my life EASIER I will certainly listen to your comments.
I like EASY, BC

I'm with you, BC..I like EASY too. I asked this in another post, but did you do these in a rotating positioner? I would have.
I still need some input on Pulser settings? Like 2pps 50% background
and 35% on time what do most guys start with on light stainless parts..
Fittings tube junctions Etc...

I think ya kinda haft do it on the fly, BC...experiment with peak and back ground and travel speed...I know you can figger it out. I never went by parameters someone else recommended....I always had to adjust it to my way of welding.

You're right when you say no two machines are the same...I ran an orbital tube welder for about 5 years, and developed 60 schedules for it for different size tubes, joints and fittings to be welded. Most it was for x-ray, and there was one part I had to bend a dogleg in the tungsten to weld it. The tungstens were only about 5/8" long. I tried to keep the speed constant, so I could vary the pulse times for penetration. I can't imaging using pulse for hand work, but I know it's done...to me, it seems to take the skill out of welding.
So, after I had been running the machine with my schedules, turning out good parts, for 5 years...the calibration lab says ''hey, we have to calibrate the machine" ( it was at the same time I was transferred back into maintenance,) so they did, and destroyed all my schedules for welding over 60 different parts...the machine has never turned out a part since. You see, they adjusted the amperage and voltage output, which all my programming was based on. They went back to hand welding the parts...now you know why it costs so much to fly.

Let me start off by saying very nice work.
I recently had my first outdoor sculpture commision and it was stainless steel (16g) now I have tigged up sheets of this stuff but it was a while ago and my first attempt was to tack it then use some 045 wire to weld it up. Needless to say I did not get the results that I wanted so I turned on the pulser (square wave 255) and dialed it in to where I could use it.
The results were amazing. Little to no warpage. **** I didnt even have to clamp the pieces down.
So like Rocky stated before. You have to find what settings work best for you. I personally like it set slow so I can control it more so then having the machine control my movements.
I think that a lot of the inverter machines are too complecated and have too many settings. Give me a transformer machine any day of the week

With the small round parts (for me) theres no way I could achieve the LOOK
I wanted without using the pulser mode....Like on the little throttle shafts
everyone uniform and the same....Too much work for me without that pulser
