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

What is stitch welding? definition and meaning

That's the def. I grew up with, but I've also seen roll seamers use that term... Steve

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.
