Is this possible? Let me explain what I'm trying to do. I want to use this tip: Which uses a tunnel type soldering/iron which the 937+ does NOT have. Can I simply buy the wand for a Aoyue 2900 and and plug it into my 937+? Both the 937 and 2900 wand appear to have the same bulkhead connector. But was looking for any more information before I waste/ruin money. Thanks
