	Hi! I noticed that some spool guns for aluminium welding can be had way sub-£100. Looking at prices for professional spool guns, they cost 5-6x as much. So the question if those cheap spool guns are any good is probably a valid one. I'm not looking into welding aluminium all day long in a professional scale, but I may have to occasionally weld the one or other bit of aluminium. And I'm OK with having to do a lot of dressing up to make it look OK, I've seen enough MIG aluminium welds, TIG is clearly MUCH more beautifull for welding aluminium. That's not the point. But if they'r utter useless cr@p and fall to pieces after 2 blobs of pidgeon sh!t, any £ is one too much. Right now I'm not willing to invest in a AC TIG machine. My welder can do DC TIG, but that's no good for aluminium, sadly. I'm currently looking into this one: www.ebay.co.uk/itm/311446607602 - the price is VERY tempting! Any experiences?? Thanks! Cheers, Jan

	Don't have any experience of them but after looking at the link would be tempted myself Might be worth asking over on www.mig-welding.co.uk/ forum for an opinion.

	Let me know how you get on with this. The spool gun in the link is very similar to the one I use at work, and I have thought about getting one to use at home- for which I would be looking at a similar level of duty/usage to yourself. I can buy aluminium wire off the shelf for my clarke unit, in the same spools as the steel, but obviously its not advisable to put aluminium wire directly into the machine, as the rollers will just chew it up!

	From reading other peoples opinions you sometimes have to tweak them to work to optimum but overall not too bad. Something else for my shopping list

	Hmmm. Looks like it needs a current feed to the spool motor? Bügger. I don't think my welder has that... Ahem.

You just need to run the wires from the internal spool motor out through a connector and double pole double throw switch for internal/external spool power.
