need some welder advice quick!

Any DC machine that welds half way decent will bring $50 easy. Typical 20% duty cycle for the smaller machines. If the machine is not running or you can't try it out, it may scrap for $15 if it's no good, so not much risk.

From the pic it appears to be made by Century. I've used a couple Century machines and was impressed with the arc stability for a cheap machine.

The dc gives a smoother, cleaner weld and is easier to control. Makes great welds on thin stock.

In ac the flame actually starts and stops 120 times per second (too fast for you to see but it does). With dc it stays lit. Also there is a big inductor (coil) in the dc rig that makes for a constant energy supply.

Short side is the dc rectifiers get hot so you have to reduce the work function in a little unit so that they don't get overheat and short out (melt).

But so what. If you are like me you are doing this for yourself and you get it done when you get it done.

Haven't seen the welder but the price sounds right.

My last welder purchase was a Miller 200/100 ac/dc and it is small like that but I gave bout $250 for it new. Works great for me after only having ac for so many years.
