There's got to be some more settings available I think. The pulse frequency is how many times per second it pulses if you're using that feature, usually measured in hz. There should also be a pulse base which is the minimum amperage in between pulses. It's usually a percentage of the main amps. For example, if you have your main amps set to 100 and your pulse base at 20% then the machine will go back and forth between 100 and 20 amps at your set speed (frequency). Mine goes up to 200hz which really isn't noticeable. I agree that the pulse isn't really necessary but it can be nice for fusion welds (no filler). This fella does a pretty good job explaining things. Might be worth a watch. https://youtu.be/aiBxGI7fn4Upholmann said:Whats the deal with the pulse frequency?

Jwhit55 said:Lincoln has an ap for amperage rating that has been for helpful for me. It tells you everything you need to know based on material and thickness. It's not perfect but will get you in the ball park of where you need to be. I learned on that machine and it's awesome! I've actually been saving up to buy one since I've been maxing out of miller 165. I'm no professional by any means but If you need help give me a shout and I'll try my best to help you out.
Beerj said:Well, your max amperage is going to be close to your metal thickness. For example, 1/8" is .125 so you'd run 125 amps. That's at least a good starting point but you could also just crank it up all the way and just use what you need via the pedal. AC balance is just like it shows on the knob, either more cleaning or more penetration. I run around 35% for clean aluminum. You may want more if there's any oxidation but it's better to just clean it off first anyway. Post flow is how long the gas keeps flowing after you terminate the arc. Very little is needed for steel and even less for aluminum since it solidifies so much faster. But you'll want 7 to 10 seconds for stainless. I run about 18 cfh flow while welding for everything and almost always run a #7 cup. You may need more flow if you use a big gas lense. 3/32 1.5% lanthanated tungsten with 1/16 thru 1/8" filler. Also, with aluminum, keep the tungsten stickout to a minimum. If the filler starts to ball up before you get it in the puddle then you're likely too far out. That's about all I've learned in the past 8 months or however long it's been since I got my tig.
