Welding Tips and Tricks

Can some of you experts take a look at this video and comment on the pulsing frequency?

I think he's welding thin gauge titanium.

He has a bunch of pics on instagram that are amazing.

Just wondering about the rather slow rate of pulsing and if it meant anything.

I'm not an expert, but I use pulse a lot. He's using a frequency that makes my brain shutdown. I use pulse at 1 or 2pps to help me control the heat when welding thin material and to give me a sense of timing for dipping evenly. My machine only goes up to 20pps, but I've used machines with much higher pulse frequencies and other than the screeching noise from the inverter, I can't say the pulsing helped or hurt anything I was doing.

I don't think there's any secret here, most use either a very slow pulse (1-3 PPS) or over 20, in between these it seems the flashing arc can be very disorienting, yet some hate the whine of higher pulse ranges.

Pulsing can help with reducing heat input and to provide a stable arc, and a better looking weld. There's such a wide range of possible pulse settings, and with the uniqueness of the weld joint, experience helps in deciding what settings to use.

I don't believe that (typically) there is just one possible set (of pulse settings) that will work for a given weld joint, and if you aren't using that setting you'll mess up.

Some people practice their timing with pulse. I don't use pulse often but when I do I like it over 50 PPS. Less than that drives me nuts.

comment? annoying

Yeah. that's what I thought. Maybe his pulser only goes up that high?

I'm getting ready to weld up a pie cut motorcycle exhaust and was researching what weld settings might help.

I think I'll pulse but at the 150-200pps range. Fit up is good for the most part but I just feel more comfortable adding filler to help the overall strength. It's only 18g mild steel and I'd rather it not thin out too much and crack after a few miles.


Soooo want that HTP welder...

That's right about stopping your brain. That's about the right frequency to give an epileptic a bad day.

maybe the guy is an ex-tailgunner.....

That would drive me nuts, I use a lot of 2.5pps and I've used 500 at times
