Subject: Help with microfoam on Expobar Pulser! I could do it on my Gaggia. . .
Hi,

I got a great deal on a used Expobar Pulser (thanks, Jack!) and have
been excited to get to know this HX machine. I'm coming from a Gaggia
Evolution with the Sylvia steam wand mod, which I could consistently
make great microfoam.

I can't seem to get good microfoam on the Pulser- it always is
separated. I don't have nearly the steam power on this new machine to
move the milk around like my Gaggia did. I can't get it to swirl much
at all while stretching, and by time I'm steaming with the wand deep it
will swirl OK, but it's never fully incorporated.

Help! I know I could do it on my other machine, and could pour latte
art as well. I also know this new machine is far better, so I want to
figure it out.

I have the stock Expobar single hole tip. The hole looks really big, so
maybe I should get the Rancilio 3 hole tip, or the Goldstar (sp?) 2
hole tip?

I haven't checked my boiler pressure yet (Pulser doesn't have a gauge)
but judging on cooling flush length to stop the "water dance" I'd say
my boiler pressure is at least 1bar.


Thanks,

Wes

Hi,

Thanks for your reply.

It seems the machine was well cared for, backflushed regularly, etc.

Hot water coming out is around 190 degrees in the cup measured by my
frothing thermometer.

It just seems like it should have more power, but I have a friend that
has the Expobar Lever, and it felt similar. I'll have to go back over
there and see. My lowly Gaggia Evolution could really whip the milk
around- it steamed a lot faster than this pulser. . .

Could very likely be the tip. I'm a cappuccino drinker so latte
microfoam is not my preference, but my Ex Office is quite a powerful
steamer. What condition is the boiler in and what temp does it provide
hot water at? If it's scaled up it might reduce the steam output?

I tink one of the best add-ons to the Expobars is the cool-touch steam
wand, but the available tips might not be to your liking. - SteveP
