Controlling the filler rod has to be THE most difficult thing to learn. So, use your pedal to pulse.
Pedal down, wait for the puddle, dip the filler, pedal off move ahead Pedal down, wait for the puddle, dip the filler, pedal off move ahead and repeat for the entire weld.
This gives you better control over the whole process. Once you get good at it you can run a complete weld without pulsing the pedal. It doesn't come quick or easy !!

Stanton: I don't have a pedal. That's my whole point. Not an option on my machine. Mr P: Is the diffuser part of the cup? Replaces cup? Seems like a good idea.

SO does your torch have a thumbwheel instead of a pedal??? MOst can be upgraded to a pedal. As said it aint a race and practice practice practice

Thumbwheel for gas, on/off with lock for power. No pedal upgrade available. Not the biggest problem. Lots of practice on the horizon. I also plan on making a jig and practice overhead tube joints before I attempt my cage. I plan on being very prepared.

Its a separate item that screws in the torch head.. they have them for most any torch.. you still maintain the flow. its just softer... I run 20-22 on the flow also which is about the best for being economical EDIT You REALLY should look to see if you can have a pedal put on your machine... life is so much easier that way

Yeah, I'm watching closely. I have the torch forward lean at 45 with my right hand, moving left. Using the #6 cup, I noticed I get a bit of wind from the gas. Is it ok to lower the flow rate? My manual wants 20 cfm, but I'm running slightly under, 18 or 19. Seems to be blowing on the weld. Keeps the tungsten clean, though. I run about 1 amp per thousandth of material plus 10 percent for pedal pulse, and about 12 to 15 cfh on the gas with #5 cup and gas lens. Like others have said practice practice and more practice.

Wow. #5 is small. Would fit real nice it tight places. Have to get me some of those. What is the object of the larger cups. I have 6, 7 and huge. I'm sure everything has it's place, just haven't figured it out yet.

I'm sure everything has it's place, just haven't figured it out yet. Yes they all have there place.. I have a box of each size.. 5-10... If I'm using a small cup I will usually use my smaller torch and bigger cups with the bigger torch... I've got 4 torches to do different things.. big to smaller and a straight one that the tungsten goes up into the handle for working in tight areas like in the bottom of intakes plenums EDIT Thats not counting the stubby back caps for each torch

You REALLY should look to see if you can have a pedal put on your machine... life is so much easier that way
But the op. is learning to tig a cage would this be ideal to have welding a cage? When I weld a cage I use my knee for the pedal or anything to get it done... if need be I will set the machine so I go WOT on the pedal... but I try not to do that.. thats a last resort

But the op. is learning to tig a cage would this be ideal to have welding a cage? Like I've said, I've seen it done by experienced people. Plenty of reasons not to though. I've done it. I wouldn't even try now. Why handicap yourself on something where appearance and weld quality are so important? IMO, TIG welding without a start/current control is like trying to drive a car in traffic with an on-off switch instead of a gas pedal. Awkward positions, changes in current needed as you run a weld around a joint, being able to control the speed, rolling the current off instead of jerking the torch away, etc. on a complex chassis project? You have to use and learn how to use a pedal or thumb control on the thing.
If the results don't match the theory, change the theory.

I have a thumb control for my machine but not coordinated enough to use it. Started with the foot pedal. It's a lot like switching to a transbrake and delay box after years of bottom bulb foot brake racing. LOL

I never use my peddle when I'm inside the cage welding. It's so much easy'r to use the scratch start option on my syncrowave 250. Only time I use the peddle is when I'm at the work bench and it's an easy weld.
I never use my Mig anymore.

I have been tig welding for over 35 years and I still can't use the thumb control worth a damn. I have to use a pedal. I even do fine with somebody else mashing the pedal for me, but can't get the thumb deal right. When I have somebody else operate pedal, I set machine where even if they "floor it" I am good on heat. When welding cages, you get to be good at mashing pedal with elbow, head, arm, knees, whatever, but sometimes you just CAN'T do it and need an assistant.
On the test beads shown............you are trying to put too much filler in. You seem to think, as many do, that a tig weld needs to look like a mig weld and it doesn't. It takes very little filler

I'm using a Snap-On Muscle Mig 140 with a Flex Tig attachment. Settings are 50/90/105/150/160/175/190 amps, all at 100% duty cycle. Gas is set with a thumbwheel on the torch. At the end of the weld, I just turn off the switch or pull back until the arc goes out, and wait until the glow goes away. Yeah, until I get the hang of it, it seems to feel like it needs more filler. Trying to adjust how much filler is required as I follow the puddle will come with more practice, I guess. Something in your head just says "Add more rod". Probably because that's the way mig welding works.
