Any welders in da house!? Rehm or Gys?
« on: May 20, 2020, 01:58 PM »
Will embark soon on a new adventure, welding. TIG that is. Right, go big or go home!?

I know it will be a daunting task to make something.... huh, how do call it? ....well just something [big grin]

Anyhow. Looking for a TIG welder, and I’m got it my choices down to Rehm or Gys.

Any thoughts?

Did you forget which country the FOG is based in?

So the real & only question is: Which Lincoln Electric TIG welder are you going to buy?

Get one that has an inverter in it, they're awesome. 

Find a local welder and pay him a fee to teach you how to safely use it for your welding needs.  Ground the work to the table and ground the table to ground. 

I had a Miller inverter and it was a lot of fun. Good luck on your decision but I have no experience with either machine you want.

Get your weld on. Good stuff

Hehe. Oliver! Yeah. But that stuff is hard to find on this side of the pond. And (apparently) so much of junk out there, that its hard so see whats a good brand :/

Just hopping for some EU welders that can pitch in.

Thanks! Was looking for some course, but in english, hard to find. Anyway I got someone that is willing to introduce me to basics (especially safety is a concern, don’t wanna burn down the house), a machine, bottle of argon and put my hood on ! [big grin].

What country are you in? What is the amp service to the future welders location?

I have an older copper wound Lincoln TIG/stick AC/DC welder that requires a dedicated 100amp service at 220 volts. It weighs well over 150lbs. The newer welders tend to use aluminum for the windings, and due to modern electronics draw less amperage. My preference is for a foot peddle. Allows one to up the amperage to strike the arc, then quickly backoff the power as not to blow through the material, plus adjust heat as you go.

What do you plan to weld? Type of metals and thickness? If you want to weld 1/2" (13mm) aluminum you are going to need a lot of power $,$$$. Even 1/4" aluminum takes a lot of heat.

Have you considered a MIG welder? Better starting point to learn, and will do 90% of what most folks need. Plus you can get a spool gun and still be able to weld aluminum, even easier than with a TIG.

First project could be making your own welding cart, that holds the bottle(s) you need. If you plan to buy two welders, plus a plasma cutter, make sure your design can accommodate them. In the USA it is best to own your bottles and not lease them.

There is a lot to know about welding, fortunately in this era for the home hobbyist there is Youtube training.

Spend the extra money for a really nice automatic welding helmet, that can do both TIG and MIG. Getting flashed sucks! The larger the screen on the face shield the better.

@Peter C

Thanks for the tips!

I'm (expat) living in Czech (woud love to do a course, but in English its hard to find overhere). I have both 230v and 400v so should be able to get enough pixies down the line  [tongue].

Mainly will be doing (mild) steel. Guessing ~ 5mm is probably max, if not then it will need some layers  [blink]. I guess once started a new world opens... ;)

My 1st thought was actually a MIG welder. But after the reads and what not, the TIG's option to welt without a filler rod and the cleaner process (no spatter, less fumes, no slack) made me want to go with TIG. Also (not 100% sure), I did understand that nowadays the modern machines have an option to set a starting current and a slope-up time. So lots of work can be done without foot-pedal.

Project wise. It's stuf around the house. Some support for tables, some racks, table (support), etc.

The share number of "brands" (if you can call it like that) of welders is enormous. Most coming from China (itself not perse bad). I do realise welding will take some time to learn. A decent machine (+ dito helmet) will make your life a heck of a lot easier. So, buy once, cry one  [big grin]

All in all, I think a nice journey to learn something new. Was thinking of a cart (seems the "Hello World" of welding  [big grin])

FWIW I use my MIG almost always for mild steel. Yes it splatters some and quit often I grind the welds flat then fill prior to painting. Depends on the look you want. Often a MIG is the best first purchase.

In building a vehicle (Rock Crawler) from scratch there was not a single steel part that wasn't MIG welded, except preheating then rod welding to the cast differential housing. 

Nothing wrong with a TIG, but first I would recommend you think about your future projects, assess your skill level, research some more, then make the decision to own multiple welders LOL

If you plan to do some artsy stuff, count a plasma cutter into the budget, and a cutting torch set to be used almost exclusively for bending metal. Which opens up another thought. If you were to purchase a gas torch set you could begin practicing gas welding skills which is very similar to TIG welding. TIG and gas welding are much harder than pulling the trigger on a MIG gun.

If you can demo both types of welders it would help you make a decision on which welder to buy.

I have to concur with the point above.  I just started welding about a year ago and I got a multiprocess machine that can mig, tig and stick.  Tig is pretty, but it is a lot more time consuming than MiG- the fume thing is nice, but not all that important unless you are running miles of bead in a tiny enclosed space.  The the point about the machine- there are lots of cheap inverter welders that sounds a great job on anything thinner than about 1/2”.

Good luck mate!  I hope to get back into welding one day. A Miller TIG would be my choice.

Cheers. Bryan.

Whatever process you use, if you get into welding stainless steel or any steel with chrome in it, be aware of the issues with hexavalent chrome fumes generated when welding, and actually with grinding too.


Read up and wear the proper PPE so you're not sorry years from now.

https://www.osha.gov/OshDoc/data_General_Facts/hexavalent_chromium.pdf

My vote would be for a Lincoln multi-process machine, but if they are not available where you are then you'll have to look for something else.

Regarding the question of MIG or TIG, I would say it depends on the kind of work you're doing. If you're planning on welding only as a hobby and not doing production work, TIG is cleaner, can weld a wider variety of metals at a lower cost of entry since all you need is different filler rod (or not, if you're just fusion welding), and gives you much more control over heat input.

One thing to keep in mind is material prep for TIG welding. I just spent over an hour today cleaning a couple of dirty metal cylinders I'm TIG welding to incorporate into my Project EVS auto-cycling vacuum pump for veneering. Overkill for sure, but I had the scrap material lying around. For good results with TIG you need the metal to be bright, meaning you have to hit it with a flapdisk or 3M material prep disc to completely remove any coatings. Working with stainless steel adds yet another step of cleaning the parts with iso alcohol or acetone, and back-purging with argon if you care about the weld long-term. I have three angle grinders and three Baldor bench grinders, all with different styles of wheels. At a minimum, you'll want a good bench grinder to hone your tungstens and a good angle grinder for material prep.

Related to material prep is metal dust, weld fumes and proper PPE. You won't want to mix metal dust with wood chips as it's a big fire hazard. If I'm grinding any coating or bare metal, I'm always wearing a full face, sealed respirator with P100 filters, usually the 2297 filter optimized for welding/grinding fumes with "nuisance level" organic vapor filter. I'm super paranoid about metal in the eyeballs and inhaling metal dust. You'll want to consider proper PPE for metal metarial prep and don't make the assumption your woodworking gear will be fine.

I'm in the U.S., so I'm not familiar with either brand of welders you listed. You will absolutely want to select an inverter machine. It really comes down to the thickness and type of material you anticipate welding. My machine goes up to 185 amps which can be a limitation when welding anything thicker than 8mm plate or aluminum, which dissipates heat very quickly. Though my projects aren't structural and don't require full penetration, so rarely do I ever max it out. If you'll be welding mostly mild steel and keeping it under 5mm thickness, look for a TIG welder in the 175a range. Go much higher and you're in the realm of water cooled machines and TIG torches which are great, but costly and probably a bit much for a starter machine.

Oh, and those clamps you got for woodworking? Yeah, they work for welding so long as you don't get them too hot:

One more thing to consider is the rated duty cycle on the machine.
I had a small project to complete and it was going to be easier to weld it myself instead of using a service. Only really neede a small Lincoln mig from HD. But the duty cycle at 10% would of drove. me crazy. I ended up buying a snap on welder,

Don't use your grinding wheels, wire brushes, files, etc. on CS then use them on SS, get seconds so you don't contaminate your SS welds with CS.
