Frequency versus Pulse

admin

Frequency versus Pulse When welding aluminum or steel  which would be more helpful on thin alum./ steel  Lets just say you could just have one which would be the most helpful ? Sport
Reply:Pulse When welding aluminium
Reply:Frequency is how fast he AC wave changes from EP to EN.  Pulse is purely current on off.  Frequency aluminum only thing.  Unless you're talking about HF starting on a tig which is a different animal.Pulse is for thin material to lower heat input and focus the DC arc.  Most say pulse on Aluminum is ever really good, cause you wanna go hot and fast.So pretty much with tig, they're totally different.   I'd take pulse over AC frequency adjustment hands down.TA Arcmaster 300CM3XMT 304S22P12 suitcase feederX-Treme 12VSOptima pulserTA161SMaxstar 150STLHypertherm PM45OP setupStihl 020AVP, 039, 066 Magnum

Reply:MIG or TIG?Frequency can mean a lot f different things,AC frequency for TIG would be how often the cycle goes from negative to positive in a second. Balance would be how long it spends in the positive side versus the negative side of the cycle.Pulse frequency, for both processes, how many time per second the power pulses.Frequency of synchropulse, pulse on pulse, double pulse, etc MIG only. Sets how many times per second the wirefeed is changed.If I can get my hands on it, I prefer CMT for thin aluminum. For tig I usually eave the balance at the default, and use the foot pedal. I might do pulse tig depending one how many parts, how much time  I have, and how bored I am. Last time I set it at 2Hz, and that worked great for my style and that particular joint. Assuming TIG, pulse would be important than AC frequency as I do more steel than aluminum.138# anvilHomebuilt 6 tap kegerator100# cone anvil5" post viceVarious hammers ranging from 250g to 2000gSome tongsA few screwdriversA wrench or twoOh, and a Fronius TPS 2700
Reply:Frequency control implies an inverter power supply.  If you choose an inverter you will likely have variable frequency and pulse.Here's a thread that will give you some specific recommendations ...

Reply:This is true the frequency and pulse ability, However, I was looking at machine that limits the pulse rated 1-10per sec.on alum only. but give you frequency adjustments independently up to 999and I don't know if that's a good thing ,in seeing how other use pulse? and the little I know of both pulse and frequency!! I know you don't get independently frequency adjustments  till you get to the Dynasty 350 (out of my budget)  I think. So, there where the question comes in  frequency versus pulse I know you don't have to have it but, the more tool you have the easier of the better you can do the job!! if you know what to do with the tools!!!ThanksSport
Reply:I have tried pulse while tigging alum, but it slows me down too fast. AC frequency adjustment is a godsend.Weld like a "WELDOR", not a wel-"DERR" MillerDynasty700DX,Dynasty350DX4ea,Dynasty200DX,Li  ncolnSW200-2ea.,MillerMatic350P,MillerMatic200w/spoolgun,MKCobraMig260,Lincoln SP-170T,PlasmaCam/Hypertherm1250,HFProTig2ea,MigMax1ea.
