Miller TIG pulse controller

[formula]

I'm working with a Miller Syncrowave 180SD. It does not come with a pulse controller. However, Miller does have the "PC-300" pulse controller box that I can connect to it. It will control background amperage, peak amperage, pulse frequency and %on time. Also, the contactor and/or peak amperage limit can be controlled by the foot pedal / hand control or the pulse controller. The best price I've found on a new one so far is about $550 I'd like to get a bigger machine with a built in pulse sequencer, but I just can't justify the cost of it. (for a while anyway)



Has anyone used one of these boxes? Any other suggestions?

Hey Sean, I too have a 180 SD. Been very happy with it. Been trying to get proficient at tig welding, but it takes alot of time and practice. Curious, what the thickest aluminum you have welded with it. I too would have loved a larger unit but since I had never even held a tig before I owned one I figured I should start with the 180 and go up from there. What is the purpose of a pulse controller?

Sorry, don't have any input about the pulse controller... .



But I am a member of the TDR Miller Syncrowave 180SD owner's club... .

From what I've found out so far..... A pulser will allow for greater amperage with less total heat input. Especially good for thin material. Also, it'll allow for better bead appearance.



The thickest aluminum I've welded so far is 1/8". That was no problem. I'm pretty sure that I'll be able to do 3/16" on a single pass quite well. Moving up to 1/4" will really be pushing things. Anything thicker and a bigger machine will be required.

Try millerwelds.com, I believe you can get the info you are looking for there.

I dont personally own a 180 but I have done a lot of tig welding. Having a pulse box can be very handy but unless you weld a lot of sheet metal and really thin stuff you will find that you dont use it much at all esp. on that small of a machine.

Yah, I think I'm going to hold off on the pulse box. When I get a bigger machine, it will have a pulse sequencer on it already



The thinnest aluminum I've done so far is 1/16" 5052. After a little practice I was able to weld on it no problem Time for some thinner stuff now.
