Hey guys, I'm looking to purchase a welder and have been looking at the Dynasty 200 SD because I can use the welder at home (110) as well as the shop (220). The main difference between the SD and DX model seems to be the pulser. Do you guys think this is a required feature?

I plan on welding mostly thin aluminum and stainless steel for my motorcycles (brackets, exhaust systems, etc.) The thickest AL will be 1/8".

 

required no but it is nice to have if you are welding long sections of thin sheet metal, it does take a while to learn how to use the pulse mode but i say get the dx its only $180 more.


i have a 200dx

oh yeah don't buy the contractors torch kit unless you want a big wp-26 torch.

in my opinion pulsing is a crutch, even more if your machene does it.

what you mean like a robotic tig welder?

 

somethin like that

 

care to delve into this more? Curious to see others opinions on the matter. I have manually pulsed all of my thicker materials, and have never had any ill effects being caused by this alone.

 

its neat but sometimes makes it hard to weld. you just need to know what your doing i guess. people have been without it for many many years so you really dont need it.

 

Pulse feature is great. Experienced welders swear by it, some do not. It all depends on the person, its a worth while function, you can adjust settings to allow your weld pool cool down faster and works wonders with stainless.

and what... foot/hand amperage controls are crutches too?

I also run the Miller 200 SD's at work, and also the Dynasty 200 DX. If I were to choose between those two, it would be the DX hands down. Although it's a bigger unit, it's also an inverter which makes it lightweight about 40lbs or so and will give you the capability of welding aluminum. Both units work well and I have nothing bad to say about them. I'm planning to purchase the 200 DX when I have the funds to do so.

 

I know I'm new to welding but aren't both Dynasty SD and DX inverters capable of welding aluminum?

 

yes.

 

It was a rhetorical question

 

some people say cucumbers taste better pickled!

 

AC is required for aluminum welding.


transformers and inverters can do AC and/or DC welding.

Inverter machines are smaller and require less amperage during operation (20amp breaker vs 60amp breaker for 200 welding amps.)

whats the point of pulsing? to control the puddle? to make a nice dime? control penetration? if your a decent welder you should be able to control those first two things without pulsing, and your lost if you think pulsing will help the third.

pulsing is slow. period. last time i checked welders get paid 'generally' by how much they produce. it also subjects the material to unnecessary rapid changes in temperature, which isnt good for many materials.

 

What, just cause you work at Full Race you know how to weld or something?

 

Pulsing is actually considerably faster in my opinion. I understand the theory and practice behind it, minimizing material distortion and heat variances, it simply isn't quick enough. I have been able to produce a fast weld with an extremely low HAZ by pulsing. I run 0.065"+ all at around 300-345amps, and rapid pulsing.

We have to produce a certain look to our welds, because that's what we are known for (Lone Star Racing, atv race stuff) so this is why we do it.

However, if you can offer any great tips for making more efficient drag welds, I am all ears! As a matter of fact, you guys are only 20 minutes away, I would be more than grateful

tony one of those things isnt true anymore

 

its interesting how there are so many ways to end up at the same conclusion. **** as long as the two pieces of metal stays together, who cares right? haha

 

Also the same that I've learned. At my work I'm required to weld thin-walled stainless, titanium, inconel, and whatever I need to weld, if I'm running a fillet weld I'd lay my wire down and pulse over it to prevent burn through since it cools the HAZ faster. Its faster to use this method in production when you're required to follow certain customer specifications, especially for aerospace.

Oh to the original poster, I forgot to mention I run the miller maxstar 200 and dynasty 200, maxstar doesn't do aluminum.

 

I have the pulser option, I used it, I don't like it. As cjackson said, its pretty much like a crutch. I'm not going to pull on my third leg, but my welds look nice enough done the right way, why use the pulse option if you know how to weld and work the pedal.

 

I remember when I bought my first TIG, I went apeshit over the pulser feature. I used it twice, hated it, then sold it (PT275). I prefer to work the pedal.

Chris, your completely right; If the metal stays together, then the job is done :D

 

I wouldn't say I pulse weld...but i definitely rock the pedal in a sine wave motion. I pull back on amperage while I'm moving across the material for my next dab

 

That about defines my welding habits also.
