Syncrowave loud arc?

Mbam · Feb 14, 2012

I have a new (to me) Syncrowave 350. I am welding some 3/4 and 1/2 aluminum together using ceriated tugsten, helium/argon at pretty high current. The arc is so loud I have to wear ear plugs. Is this normal?

I've never used a square wave machine before so I don't know what to expect.

Thanks!!

It should be fairly loud above 250 amps. If you turn the HF down a little it will hush it up a little, and maybe set the AC balance at 2.

AC is naturally louder than DC, but if you really want loud, get a Dynasty and turn up the Hz to 250.

Yes it will be loud at the the amps you are running to weld 3/4 and 1/2. The balance knob has nothing to do with the sound -------------

Get some 100% helium and weld it on DC if you want it to be quiet.

I disagree. The balance knob will make change the sound pitch of the arc. If you have it set for max penitration it will have a sharper sound. Max cleaning will have more a hum. I have had several of the sync 350's.

And yes, the Dynasty has a wicked sound to it, But wow does it weld awsome on AC.
