We've had a couple of Syncrowave 250 units in our shop for almost ten years and recently purchased a new 250DX. We've had some problems setting this new machine up to operate like our old 250's and our dealer has been nearly useless in helping us with our problems.
1. When the Amp control on the unit is set to, say 200 amps, the foot control, all the way down, will only show around 160 on the display. What's up with that??
2. We've always used our older 250's in HF Start mode but the new 250DX doesn't operate the same way in HF Start mode. It doesn't start with a steady arc, it takes off with a kind of "machine gun" arc, on-off-on-off-on-off, with the interval between on & off decreasing each time until a steady arc develops several seconds after activating the foot pedal.
It's hard to describe but hopefully you get the idea. It seems like it's intentional & not a random malfunction, in that it's very consistent in the timing of the "machine gun" effect. Once you get past the "machine gun" effect it seems to work normally, it just makes it very hard to start precisely.
We've found that we get a nice steady arc from the start when we put it in Continuous HF mode but the HF interference is also continuous when it's in that mode. With our old 250's we get the same steady arc in both the HF Start and Continuous HF modes, so we're not sure why the new machine is different.
Any help would be greatly appreciated
