pulse tig differences?

found this tig welder for around $500, so what's wrong with it? looks like it's DC so i assume it won't do aluminum, but what's the difference between a (regular?) and a pulse tig welder?

I recall reading in an AWS welding journal something about pulsed welding resulting in cleaner, more uniform welds...

however, I am too lazy to go dig though our library to find that magazine...

weird then that it would be cheaper, unless this is limited by its DC-only build.

if its dc only, $500 would be the reason.

reason why a pulse welder would be more uniform is because the amount if time the machine is welding are all consistent.

You get what you pay for. My millermatic syncrowave 250 dx has never let me down

Thats the way to go. They break the bank in the beginning but they pay for themselves in the end.

Kempii 200 amp ac/dc/hf/pulse here

Rarely use the pulse but it's good for fumble fingers (me) on thin aluminium.

I'm thinking the one here is a miller hf/ac/dc/pulse. I've used it about once in the last 2 years lol.

Thermal Arc AC/DC square wave with pulse, slope and adjustable freq here. Pulse allows the weld pool to cool during the background current. Good for thin metal and out of position (think vertical or overhead ) work...
