That is tough. Have you tried going half way, stopping, then starting on the other side, meeting in the middle? Restarting on the other side lets the part cool, so you won't be too hot on the edge.

well, I have HF start and a foot pedal. In my case it aint the machine, its the operator malfunction. I am thinking about getting a new torch. My current one is a wp26v weldcraft, 200amp. This model has the cable and airline going into the torch body. To me it makes for a very heavy torch and as I weld, I notice I let the torch angle droop. I think going to a torch with just the hose, would make everything a little lighter. I have a couple of 9v torches, one is a flex head. All I really need is the hose and connector block for the weld lead. All three of my torches have the air valve on the handle, but air flows thru, and is cut on and off by, the machine. I think the 9v is rated for 125amps, but would have to look for the specs to be sure.
one thing I like about the ft pedal is the ability to just ease off the pedal if I see i am getting to hot. I try to adjust the heat so that I am welding with the pedal fully depressed, but as the metal heats up, being able to let up off the pedal helps maintain a constant travel speed.

I like having it set so I'm welding most of the time at 3/4 throttle or so, then I have some more so I can floor it to get the puddle started then back off as i go along the joint. High frequency and the pedal are nice don't get me wrong but there are tons of guys who make X-ray welds with a gas valve scratch start torch every day
Yes I do that when I remember; but sometimes, no, frequently I forget and weld to the end. Need to build a habit pattern so I always do that.

You are not alone. I try and buy the best equipment I can afford, and that does help, but nothing makes up for operator error.

My goodness, I gotta learn tig!!
You guys make it sound like it's as much fun as driving a sports car. :laughing:

It is. But like learning to drive a sports car, you may crash and burn at first. Remember keep a tight arc, so tungsten close to puddle, but never in it, remember a rhythm for move, dip, move, dip. The experts make it all look so easy.. it is not easy, but your are in control of everything, so if the results are not what you wanted, it is your fault!

Maybe not fun exactly, but certainly interesting and useful
After the first 100 hours of practice it gets a lot easier.
Not cheap to learn when figuring filler and scrap for stainless, aluminum, and steel - plus argon - but it pays for itself pretty quickly when work comes in that you previously couldn't do.
