HTP Invertig 301- the Ins and Outs

[@chrishevia]

Great job Tyler! Nice machine.

[@Mikael5732]

Doesn't the Invertig 221 have the same feature allowing you to adjust the amount of amperage for the positive or the negative cycle? By the way, very nice welding!

[@usaweld]

That is correct

Hi, can you let me know how the Miller 300 or 280 compare to the 301, I weld .030 to .040 alum. My Miller 210 goes down to 1 amp, will this handle that light of material? let me know thanks

[@TJCaton91]

Yesh it goes down to 5 starting amps. I've welded razer blades with ease as well as some .020 jobs. Plenty of arc stability for thin gauge jobs.

Your miller 210 has a non disclosed and non advertised hot start in tig, that what mean is: you are not really starting the arc at 1 amp you are starting it (deepening not he tungsten diameter you have selected) at anywhere from 70-140 amps .... this "blast" of amperage is only available for a couple hundred milliseconds and tapers off quickly but that is what is blowing holes in the soda pop cans when you try to weld them and why you have to ignite the arc on the filler metal .... the HTP has a 4 amp minimum not a 1 amp minimum but you can adjust or even turn off the hot start so that you can actually start the arc at 4 amps .... 4 amps are "good for " as low as .004". you welding 030 or 040" is not even really challenging for the machine. the 400 Hz ac frequency and triangular wave would also help you to weld thin material but at the thickness you are inquiring about it is not even close to necessary. thanks

@@usaweld Is the Invertig 300 locked in using only the square wave like the Invertig 221? I have the Invertig 221 myself. Thanks.
