Anything welding

"since I'm never sure where I want to have an outlet"

All this time I thought I was the only one...

 

I was wrong in my earlier post. It's not the trigger control causing the failures, it's the "raw voltage" signal. Users have posted pics saying it's necessary to direct connect those wires as shown in the pics. Trigger controls can feed through the CNC port.

I still plan to call Primeweld and discuss. I have 8 mos left on my warranty, so I am hoping they say it's okay to make those direct connections inside the case. If they say no, I guess I will try using the CNC port output into a relay, then feed the ECU. It's irritating to have to do that, but I definitely don't want to fry a board and have no warranty.

 

Never having dealt with Primeweld I am not sure about the warranty .

With Miller and Lincoln as long as your wiring did not cause a major failure then you cry warranty your good to go

I am sure you will get it up and running

 

I hope those aren't what you are using to fire the torch. Aren't those the terminations for the ground clamp and torch main feed? No way would you want that feeding into your CNC controller...or is this where you will grab your arc voltage to control your height control?

I'd love to see a picture of your controller without the cover.

 

This is making me want a plasma cutter soooo much!!! Especially one with a sharpie for marking all the bend lines. (Have you seen that from stuff made here?)

On another note... in anyone in norcal wants it, i am giving away my DIY'd prototype RTT Rack. Posted here: https://www.tacomaworld.com/threads...ent-frame-bed-rack-free.738948/#post-26304438

 

say whaaaaaaaaaaaaaaat?

the sharpie feature would be amazing

 

What is this sharpie feature you speak of?

 

Man you guys make me feel so behind the times. I just picked up my first TIG machine(with assistance from a forklift) and am slowly figuring out what all I need to make it live again. Got a foot pedal and 25 foot long Weldcraft WP18 torch with it. Lots of rehabbing of old hoses, etc but hopefully it’ll weld as nice as the old timers say it should.

 

Nice. Make something and make us embarrassed of or own welds.

I wish i was a lot smarter because I don't think i could make this thing myself! LOL!!! But, wow, do I want one.

 

You did take it for a test drive before loading it on your Truck??

I do love those old transformer rectifier machines and so does my electric company

As long as I never want past 1/2 output I could use a 60 amp breaker but that #2 AWG cable was a tad expensive in copper years ago.

 

Those were pics I copied from Langmuir's website. They were what someone posted as a workable solution to routing the raw voltage through the CNC port. Basically, direct connect inside the machine versus through the CNC plug on the back of the cutter.

I haven't hooked up the raw voltage or trigger signal wiring yet. I am going to call Primeweld tomorrow and get direction from them

 

I talked to Primeweld and they were fine with me wiring the raw voltage feed directly off the internals. No problems with warranty. Primeweld is a great company and one of the only ones offering 3 yr no questions, mailing cost covered warranty. 24/7 customer support originating in the US.

They told me only 6 people had reported problems running the signal through the CNC port, but they understood not wanting to risk having the problem and damaging either my plasma cutter or the controller on my CNC table.

I finished it over the weekend. I had a good idea for passing the wires through the case, so I thought I'd show a pic. I used some of those door bumper grommets I scrounge from Toyotas at the salvage yard. Drilled through the centers. Worked great.

That little box is what reduces the voltage down from whatever comes out of the cutter (approx 100-150V) down by 50:1 to feed into the controller for the motors and torch controller. It turns out that is the source of trouble for the Primeweld and other models working with the Langmuir CNC tables: the cutters' internal step down voltage boards (before it routes through CNC plug on the cutter) has a little too much fluctuation in its "50:1 output reduction" for the liking of the Langmuir CNC table controller.

Basically, the Langmuir controller wants to do the reduction itself and control it a little better. Luckily Langmuir set it up for either input: full voltage, or already 50:1 reduced. They set it up that way because a lot of cutters don't have a CNC port on them, so customers have no choice but to tap internally for the raw voltage signal.




Now, if I didn't have a leak where the two halves of my water table were joined with silicone and bolts, I'd be completely finished

Looks like I am gonna have to pull up my big boy pants and try to TIG weld the halves together. It's stainless and I have never attempted to TIG any stainless. I am barely competent at TIG on reg steel.

 

FWIW, I think stainless is about the easiest thing to TIG!

 

Got my Systematics MP230 back on solid wire and CO2 today. No more flux core for my big boy welder. Now I gotta relearn the settings and get the wire to feed smoothly. Seems like I’m missing something to
space the reel off the spindle so it lines up better with the feed rolls.

 

1st off, wire will never feed smooth off a crossed spool. The tension on that wire needs to maintained as you thread it over the rollers and into the liner.

If that roll was mine I'd already know I'd be having feeding issues pretty quickly.

 

I've had a Primeweld Tig225X in my Amazon cart for a while now (so I don't forget to research it when I get the time). How are you liking your Primeweld? I may pick it up as a Christmas present for myself (a great excuse to buy more tools haha).

Also I'm planning my first foray into stainless tig for a motorcycle exhaust and was quite nervous to try something new but after a bit of research, I'm reading that it welds pretty much like mild steel and not so nervous anymore. Get a practice piece or two and call it a day

 

It's my first TIG welder, so take my opinion for what it's worth, but I really like it. Why? I like all the analog (dial) adjustments. The graphics on the face of the unit make it easy to understand the relationships between the dials, but there is still a lot to process. I was also figuring after the 3yr warranty, if a dial goes bad I can fix it myself vs a more board driven unit that sets everything for me. I think it's a survival instinct having always repaired all my own vehicles, HVAC, plumbing, electrical, mowers, roofing, .... I mean, I've even thought about using a borescope and doing my own colonoscopies. Have I crossed a line maybe...?

Probably the foot pedal is the only small complaint. It's pretty stiff. Makes it difficult to make small adjustments. I mounted mine to a piece of wood and am still using it. Just too cheap to get a better one for no more than I use it right now.

The arc welding is really smooth. I had marginal ARC welding skills. I've always MIG welded (love my Hobart 150) and let my Dad handle the ARC stuff, but this thing makes it seem really easy. Maybe all inverter machines are easy to ARC weld with, but I know this one is smooth. My Dad has always had the Lincoln tombstone and I had him try the Primeweld. He was really impressed with the consistency of the arc, and the ease of striking.

If you want a plug and play that has presets, don't get it. I am enjoying trying to learn where to set everything for the TIG functions, but if you want quick functionality, I'd look elsewhere. I will say though Primeweld customer service is hard to beat.

This was right after I set up my cart. I used a HF dolly for the tank and the rest is just junk from around the garage. I added a small grinder for my MANY needs to re-grind my electrodes after contacting the work surface.

 

PVC pipe makes great spacers ! Does that not have a hub brake ?

Never hurts to install a new liner

 

Get yourself a Thumb control opens up a whole New world of Out of position Tig welding.

It most often takes one time trying to work a foot control with your thighs
