MIG welding is pretty easy, once you find the settings and you know what your welding. TIG is similar to oxy/acetylene, bit of a knack in doing it. If you get the ali too hot it just collapses. Keeping the filler rod and weld pool going is something you need to practise at.
I only did it as an apprentice and struggled. (read sh*t)

How much is the one you are looking at? You mention ac/dc, so you want it to do alloy then? I'd like to know how you get on with it, if you only plan on using it on steel it maybe OK??

The tutor at the college I went to mentioned that sum of money funny enough, this was some years back now so I dunno,....it would be great if £379 would get you one good enough for home/DIY use at least.

About six yrs ago I wanted a tig AC DC unit for found bite at home on bikes.
Well I looked at them in welders supplies £1200 up for a decent make one.
Liked at Chinese ones and was told most even branded new ones are now built in China.
Anyway I bought a Cobel 200amp with foot pedal, reason was Cambridge welding supplies this was there home branded unit.
Cost me £430:00 was cheaper out there but thought UK welders supplier best options.
Bloody packed up six months after I bought it so no after care servicing repairs.
R tech I know few people with them break down quite bit

I have a 150A Cebora from work that was getting thrown out. It's DC only. I was seriously thinking of the R-Tech AC/DC but £1,000 is a lot of money. I have resigned myself to not doing aluminium unless I do spend a lot of money. It would be nice if this £380 welder did all it claims to do and lasted for years. I guess it would have a years warranty so if it did pack in it could be returned and you would get your money back. have you seen the "clipping  " hammer and screen it comes with? Look like kids kit they would sell in Toys R Us It's disappointing to hear about the R-Tech welders breaking down. I've heard nothing but positive reports. Best case is we hear from you in six months, you've bought one and it's still working great! |

I have a Tig welder (Tech-Arc) they aren't cheap, but when I researched it (a lot), the more I read about cheap systems/setups the more I decided if I was serious about it then I had to sepnd the dosh, I managed to find a virtually brand new unit on ebay for £800, they cost £1500 new, I then spent £200 on a foot pedal control and a WP9 torch as I found the WP26 a bit heavy and cumbersome. The next thing I bought was a top quality welding helmet as even though I thought the mig "parweld" helmet was good I found I was struggling to Tig weld properly. The new helmet (£300) was a revelation, the differences was virtually night and day. Everyone I spoke to about TIG welding said if you are trying to learn it, then your much better off spending the money on good quality equipment etc otherwise you'll spend all your time making a mess and blaming yourself, when its most likely the cheap equipment that is making it harder than it should be - I know some lads have gone on night school courses to learn how to do it first before investing in kit, then they have the knowledge to know exactly what they need and what is likely to work, I don't think any of them bought cheap kit after doing that. HTH Just researched my welder, they have come down in price (bought mine 5 years ago now), they are much cheaper, see link --> technicalarc.co.uk/product/ac-dc-216i-276t-ac-dc-tig-welding-inverters/New one on ebay --> www.ebay.co.uk/itm/Technical-ARC-AC-DC-216i-Tig-Welding-Inverters/322358590348?hash=item4b0e11bb8c:g:fQMAAOSwnHZYUCaw |

I've had people who are paid to weld/fabricate tell me that the MIG they are using is sh@t. I'll have a look and see the tip is loose, the wrong size (a popular one is to go up a size to stop the wire sticking in the tip), the feed rollers are too tight or slack and the liner has gone. I like what you did there "night and day" Got my first react to light screen bought for me for my birthday a couple of years ago and it was a revelation. I don't think it will have cost more than £30 or so but it's made things a lot better, even using only 15/20 Amps. I've heard that statement "you get what you pay for" thousands of times. Where does that leave my free TIG welder or my £20 stick set? It's a very rough guide at best. I've made dozens of items with my £20 stick set including my bike trailer, workbenches, stoves and gates. If I decide to go for an AC/DC plant I would seriously consider the one you have. I do believe in personal recommendation as long as it comes from a reputable source such as yourself. |

I've also had R-Tech units recommended to me.
A local shop has been using them heavily for years and rates them.
Still stuck on MIG myself.

Whatever TIG you choose, a foot pedal option is a must as the arc is controllable. So much easier to feed in the power slowly with the pedal rather than a stop/start set-up.

They don't show the TIG torch in the photos which seems to suggest it's an extra. According to the manual the gas goes directly to the torch so is either controlled by the torch or is permanently on when the bottle is open. Uses a lot of gas or a faff to turn on/off. Not a consideration when someone else is paying for the gas i.e. work. Funny, now that the only welder I use is at home I always turn the gas off. Never bothered at work  . I bought a cheapish TIG set before and it didn't have high frequency start. It was 'lift' start. Right pain in the @rse. You couldn't just put two things together without clamping, the starting thing would just knock them apart. HF start and a react to light screen is much easier. We have a few TIGs up on the mez deck at work, like a welding plant graveyard. I think they're there because they can't be calibrated, seriously, it's because they have dials to set the Amps. When the guy do weld tests the inspector has to record the settings. Without a digital read out it can't really be done. Load of b@@locks. The setting is just a guide anyway but this is the modern world. I might see if I can find out about them and if any can be released into the wild. |

Been doing TIG on and off for 40 years and only worked one place where we had a foot pedal and it was 1983!! It was an Aluminium specialist place though. |
