I like to run the AC frequency at 250 on my Dynasty 300.
Nice work.

Couple tips that might help. When working with aluminum, get your self a stainless steel wire brush. Don't use it on anything but aluminum! Clean your weld zones just before welding with the stainless steel brush. Get a Scotch-brite pad and clean your filler rod just before welding too.![]()
Thanks. I have the brush, but forgot to use it. That aluminum is some I pulled from the scrap pile so it had been outside for over a month. The welds aren't pretty, but they're strong enough for this project and don't leak water. Argon was expensive, $207 for 150sf bottle (includes bottle).
Well then I guess I cannot complain. The 150cf bottle was the same diameter as the 80 but about 5' tall. I learned today that scrimping on argon just makes for dirty welds and uses up tungsten faster.The largest argon bottle I can buy around here is 80 cu ft and about $280 including first fill.

It actually works quite well. I have noticed that most of these Chinese machines have that same style pedal and I just didn't like it. If you are used to a rocker style pedal this gets pretty close and is a 5 minute fix.Can't say I've ever seen anybody operate a foot pedal like that before.
Are you cleaning/brushing the oxide layer off of the aluminum before welding? Hard to tell from the pic but looks shiny as tho you did not uses a SS brush to first clean the alum?A little play time with the AHP today. First time using the foot pedal which I found a little awkward for my battle worn ankle, but I came up with a quick fix with pallet foam that doesn't void the warranty and allows you to rest your foot on top of the pedal, keeps it from sliding, and for me gave me much better control: <img src="http://www.tractorbynet.com/forums/files/welding/425186-ahp-tig-welder-200x-pedal001_zpshjgqslku-jpg"/> <img src="http://www.tractorbynet.com/forums/files/welding/425187-ahp-tig-welder-200x-pedal002_zpsnf05ur6y-jpg"/> First using the pedal. I have actually repaired a chain guard, a water pump housing, and a clutch cable end using the torch trigger in 4T mode. I think the pedal will make these small jobs easier: <img src="http://www.tractorbynet.com/forums/files/welding/425188-ahp-tig-welder-200x-150516_0003_zpswllabvkw-jpg"/>
