That guy doing all those videos is a cool welder with plenty of hot tips Hahaha!
Seriously, the key here is an Oxygen-free flame due to that mixing chamber and which is a bit hotter than the normal 2700C oxy/acetylene flame mixed in the nozzle.. he can weld anything other than titanium, using 1/2 the gas, even Mild Steel rods on chrome moly, and the cutting is incredibly impressive for gas - plasma quality.
Yes, impressed, back to gas for me - I'm saving for one now!
hi harryman, didn't and still hav'nt read all about it, just a quick glance at something being welded,the paint damage at a glance looks the same as mine,set up wise?i'm set up, might not be as attractive, embrittalment? doe's that mean brittle?, never had a prob with mine, range of metals? maybe not,quality? why not? and my gear is a lot cheaper, not having a go at you, just trying to justify the cost , from a scrimper, cheers, ray
I'm no gas welding expert, stopped after 4 years when I was 20 or so, many moons have come and gone since then. But my dad's still gas welding at 86, whilst I'm struggling (but improving) with MIG, having an interest in a couple of off-road vehicles that need it from time to time. I've also seen a fair bit of aircraft industry welding, and how slow it can all be to get the quality. But I've just watched all those videos, maybe if you do too, you'll see what I see - 1/2 the gas (isn't it a pain getting those 'slightly dodgy bottles' re-filled by favours?), a smaller jet, less dependence on exotic rods it seems, apparently much easier welding of rusty steels, and TIG-like quality welds of chrome-moly tube. As well as a quick switch to very accurate cutting. The ally weld was impressive, to say the least and about the only change to the setup was a slightly carburising flame for stainless steels.
OK, maybe I was blown away by the good PR and carefree presentation by an expert welder - but there must something in it - and I think that something is in full mixing of the two gases in the torch's pre-chamber prior to combustion.
So I could be wrong, but if intersted at all, its worth 30 or 40 minutes working throuigh all those videos if you have a broadband connection - I found the video quality was quite good enough to see what was going on, and what points the presenter was making. Enough for me to want to get my hands on one...
hi, really got this post going have'nt we? pity no one else will get involved i agree with your reasoning please send me your results
sorry, didn;t see ally welding, got to go,youiv'e got me exited now , cheers
The Henrob looks a great piece of kit I'm just about to order some oxy-acetylene gear and was tempted to import one but I'll see how on get on with regular stuff first.
If I was ordering one I'd have to get the FULL kit which is $459 (£250) which works out expensive for me as it's only the torch end and I don't have anything else like regulators, flash arrestors, hoses, trolley etc.
No, unless its marked up as some much lower value, expect it'd be clouted with import tax too - quite ridiculous. Though sometimes, things arrive without being held back by customs.. haven't quite worked out the trick yet.. can they be sent tax paid then?
Well ive gas welded all my life ( yeh started when i was 7 ) , all i saw was a good gas welder doing nothing different to what you can do with any ORDINARY gas torch, and BOC have a wide tip size range, the gas saving mm well it sounds a lot but how much do you save over the cost of the new gear, and how long to recoup the out lay.
Mollie tubes , well i race a bike built of Renolds tube ( same stuff ) i wouldnt let that guy near my bike with a copper/steel filler rod,, i only got one life id like to keep it. However having said all that i was very impressed with the cutting on thin sheet, very neat would like to see more and try it,, but then agian with plasma sets costing so little now.
Seems the thrust of it is better mixing, less unburnt gases in the flame and so they say, a somewhat higher temperature... they do seem to make a thing about welding chrome-moly easily,but is it tested against a similar TIG welded joint afterwards. Isn't it traditional to braze Reynolds into sockets, like the 50's and 60's British motorbike frames
