Yeah well the noise I was talking about was holding the torch far away from the work piece when purging & adjusting the flow rate, I don't remember any other machines I have used in the past doing that I remember just hearing the gas flow, the new torch from AHP should be here soon & if that...

Yeah your right there is no pre-flow on this machine, but come to think of it I remember using post-flow to shield the area prior to welding & not seen any improvement, new torch is on the way from AHP if that doesn't fix the issue I'm starting to lean towards contaminated gas.

Yeah AHP is supposed to be sending me a new torch, the other thing I noticed that seems weird is when I step on the petal to purge gas/adjust flow rate away from the work piece it makes a buzzing sound, like its trying to establish an arc and grab onto something within the torch, I have never seen t...

It's weird though cause other machines I have used with high frequency start like lincoln's or miller's I don't remember them ever doing that, but that set aside I have been cleaning the material with a flap disc then wiping down with acetone, cleaning the filler rod with acetone, sharpening the tun...

I believe the pre-flow is programmed in the machine and not adjustable, post flow i usually have set around 4-5 seconds, welding mild steel, usually 1/8" thick & 3/16" thick coupons, I will have to get some pics together, what about the torch arcing away from the work piece?

I have an Alpha TIG200X and get porosity on starts & stops, found a couple leaks in the torch, was able to repair one and not the other, in the process of dealing with AHP to get a replacement, another thing I noticed is when I purge gas & step on the pedal with the torch in the air it makes...

Hello all, I have an AHP Alpha TIG200X that i just recently purchased and have been experiencing issues with porosity ever since I got the machine, have tried different filler rods, tungsten, base metals. I am getting the porosity on starts & stops & some arc wander on low amperage, prepped ...

Hello all, new to the forum, have been watching welding tips and tricks on youtube for a quite a while now and glad I found this forum, I am a utility worker for my local natural gas company, studied welding technology back in college and used to do it for a living, now I am just a hobbyist welder s...
