Miller Dynasty 300DX vs Synowave 250DX

[HAWK]

hotrodwillys,

I think we missed answering your question regarding what the D300DX has over the Sync 250DX in the AC welding of aluminum. The advanced squarewave arc of the Dynasty only uses high frequency for starting the arc and then it cuts out. The arc is almost infinitely adjustable in frequency, electrode balance, and pulsing. I hope this helps. Also the inverter arc will weld thicker material amp for amp than will a transformer machine. I have welded 3/4" aluminum with complete penetration using the D300DX. It is a great machine!

3/4" aluminum that is unbelievable! thanks for all your information Hawk, it really helped me in my decision to go with the 300DX,this is a great site thank you everyone for all your help. Dave

Dave,

It will take 300 amps on AC using straight argon to get complete penetration on the 3/4". It will also take some practice. Enjoy!

Now change you gas and some other parameters and wow!
