Hi, I have a Syncrowave 350 that I traded for a year ago, when i first got it I welded mild steel and some stainless with it and it welded fine. However I just tried to weld aluminum with it and I had some interesting problems.It seems that when I switch the HF to continuous it just stays on. I get little arcs everywhere if the pedal is down or not. I can see and hear arcing inside the welder also?I tried disconnecting the pedal to see if that changed anything and it did not.Any Ideas or suggestions would be great, Thank you alot!!

Tonight I tried a Syncrowave 351 for TIG welding aluminum. I am pleased to say that I produced very nice beads with this leviathan. I had the current set to 160A. The big Sync must've been yawning
Unlike the 200DX, the HF is on continuously. I too had a few Dr. Frankenstein moments with long unwanted arcs. Also, at the end of the bead I had to deliberately push my heel into the pedal to get the arc to go off. The HF in these machines is created by a spark gap, which is what was used in the very early days of radio. So if you what you are seeing inside the machine is the spark gap, I would think that is OK.

I had the same issue. I removed the covers and found a wire going to the spark gaps had laid on the chassis of the machine and had worn a hole in the insulation creating some irratic behavior. I repaired the wire and it welds fine now.Dynasty 400 Wireless
