120-Volt Mig welder.

You are using the term pulsed weld to describe this. That is incorrect. This is start, stop, repeated. Others are correct saying this is not a good method for structural welds due to many reasons. A welding machine that has a pulse setting will not turn off the welding current during the pulse. It has a background current that keeps the puddle molten and then a higher peak current. The idea is to reduce the total amount of heat into the base metal while still maintaining good penetration in the weld. I have found this feature to be nice but not a value unless used in high production welding environments which I do not do. I do have this feature on both my machines but rarely use it.

Watertight is no problem, it's a pretty quick pulse, about as quick as you can work that trigger finger. I have never quantified it but guessing from memory it's about 2/3 on, 1/3 off.

Why watertight, does it hold liquid? Or just to exclude water so it doesn't leak rust stains or fill with ice? You can do that with paint if the weld is decent.

This pic is 1" x 1" x .065" (=16ga) pulsed with .030 wire. You can make it a little tighter with .023 wire. I think you'll pick it up pretty fast.

OK the term "pulsed" is an established welding term and doing this type of weld (with a MIG trigger) is not "pulsed welding". Good to know, thx!

So then can we agree on 'triggering' as acceptable terminology?

Dragon, as I posted earlier I've always heard it called (by several pro weldors in industrial environments) as "trigger welding" - dunno what other names it goes by in different locales... Steve

Stitch welding is what that is

I gave $26 for the regulator, and I think it was $90 for the 17V torch, I did not need a power block as the torch had a 10mm DIN plug on the end that plugged right into the the Everlast welders DIN plug socket. I have seen torches from about $70 and up on e-bay. depending on what comes with them. Mine had some accessories, several cups, collets and a back cap and a tungsten.

I can't answer what the LWS will do with the tank swap out. I think the argon regulator will work with CO2, but I don't think it reads right. I might be wrong on that. But at about $26, I did not consider it a large investment.

So looks like this torch is $57 and even has the switch if you convert later to a welder with HF start. it comes with collets cups backaps and has a DIN connection.. This looks like a good buy to me. I would be happy to answer any questions to people just thinking about getting into TIG.. I am no expert, by any stretch, but I have been down the road and might be able to help.

Well, I've got a torch coming from ebay. Gave $5.44 plus $15 shipping. Probably take a few months to get a set going. This one I ordered has the dinse connections, which my machine doesn't have. I will need to get a regulator or flow meter (what's the difference and or what's better) and a tank of gas. I'm doing this on some odd stray money and will be trying to find steal of a deals. Also wife's due to have our 3rd kid here in like 8 days; so hobby time/money will be in short supply.

Stitch welding is what that is

In my experiences a "stitch weld" is like this.


It's a very normal style of welding.

But the "triggering" that's being shown is just overlapping tack welds - as I noted earlier, I only use them for thin rusty stuff or maybe car sheet metal repair. For normal welding I do not use this repeated tacking method.

I like it - it's a reminder to myself really. I've found it really sucks when I "know" something that turns out to be false and then have to unlearn it.

As a result, I try to be very careful about what I post so I don't inadvertently pass bad information.

One bad part about welding is that terms used in the US don't always match other countries.
For example, I've seen some foreign built migs that refer to tack welds as stitch welds.
But in common welding language, most people know tack mig welds as a single tack.
But with heavy welding a "tack" may be up to an inch long in some cases.

What you want is the regulator/flow meter I posted a link to in post 160. It is both regulator for the high pressure (over 2000psi when the tank is new) and flow meter to set the of the argon flowing thru the torch. Set it for about 15 cubic foot an hour to start. This will work for most things. Look at the little suspended steel ball in the vertical column. The gauge shows you how much pressure is left in the tank. the fitting on the right is to fit the tank the CGA 580 connection your argon tank will have.. USE NOTHING to try to seal it.. just attach and screw on the collar so so tight with a small wrench.. Then depending on what fitting your torch hose has , barb fitting or screw on, attach it to the lower connection. I hope your torch came with a valve. like the one in the link I posted.

Start with a #4 or 5 cup, and an 1/16 tungsten, and maybe 40 amps. Stickout the tungsten about 3/8 of an inch from the cup, make sure the collet is tight, put your POSITIVE ground (very important) work clamp on the work piece. Then your NEGATIVE torch lead in the negative terminal of your welder. turn on the valve (very important) first, hear the gas flowing at about 15 CFH, flip your hood, or better yet have a good auto helmet, and hold your tungsten near the workpiece and strike your arc (momentarly touch the work at an angle), and then hold the tungsten about 1/8 inch above the work to form the puddle. You will see what looks like an umbrella of the arc, form your puddle, and move the tungsten to move the puddle and dip and add filler rod. Coordinate the movement off the tungsten and the dipping of the filler rod as you move along the seam of the joint.

Well congrats on the third child! Oh and the new torch

Not saying its factual or not. Just stating what it is called by everyone I have worked with. Which are NOT pro welders, rather multi-craft maintenance.

By the diefinition listed "a series of short, equally spaced welds", then that "triggering" or "overlapping of tacks" is indeed a stitch weld.

Short....Check
Equally spaced.....check

That reminds me of some real life experience of mine. I have taught somewhere between 800 to 1000 women to handle and shoot pistols. and a few men. The men all come to the "party" with preconceived ideas and false knowledge plus a lot of macho bravado. The women don't pretend to know anything, they are like sponges, they just soak up the knowledge that is presented and learn rapidly. The men, have to "unlearn" a lot of stupid ideas first.

That's what the M-16 instructor told us too - all of the female recruits did just fine the first day.
Some of the males had to re-train because they didn't listen the first time - even though the instructor warned everyone it was going to happen.
I paid attention in basic because I didn't want to be one if the idiots he was talking about

Internet generates 'husbands tales' like theres no tomorrow. Sometimes dispels them too. I wonder how many more are created than dispelled. I guess if people wanna believe something its difficult to dispel.

When I was in Army Basic at Fort Jackson in 76 for some reason or other the men and women trained on the ranges at the same time. With the M 16 those girls beat the pants off the guys hands down. The small recoil and weight made it easy . Of course they didn't come close to the prepackaged experts like me being a North Country Ridge runner all my early years. And for my superior marksmanship what did I get for a reward? Pulled off the range since I zeroed right off the bat and the honor of humping ammo the rest of the morning for the M60 machine guns. Then in the afternoon I got a break and got switched to hauling railroad ties (and we were the tractor). Thanks Uncle Sam. Something tells me my experience is not unique.
I did learn something very valuable though and that is the true even today and that's the appreciation for weight of heavy caliber ammo. I could take two cans of M16 and run with it while that big wonkin box of .308 I could barely waddle. Another useless lesson learned.
