The iron holder angle can be adjusted and there are many angles to suit.
I think we have a different unit, mine is the modular system so the iron holder is seperate from the station, so fumbling blindly wont get me burned.
The commonest JBC units we have do not appear to be adjustable and it is an all in one unit. I think they are quite a few years old and I would hope that JBC have learned a few basic lessons in soldering iron ergonomics since then
We have several communal soldering workstations in our various engineering labs and the commonest question about the JBC is "how do I turn it on?"
This is because the person that designed it put the on/off rocker in the worst place possible, hidden under the back in the corner directly under the hot end of the iron.
For me the worst thing about them is the fact the cartridge tips can suddenly get very hot and glow red or even orange if something goes wrong in the feedback system.
When it first happened to me I couldn't believe the iron could get so hot so quickly in open loop. I assumed that the skinny cable from the iron to the base unit had developed an intermittent connection but other people say it is a clue that the tip is faulty and needs replacing.
I've seen this happen on more than one JBC iron. Our irons see a LOT of use with lots of users visiting the workstation and maybe the JBC irons we have are just too old and worn out now. However, we have plenty of older Weller irons that are still working fine.
Clearly the excellent thermal properties of the JBC irons involve their ability to pump lots of heat into the tip very quickly. However, when this system fails open loop then it is quite a sobering sight to see the cartridge suddenly glow bright orange. No way would I have this type of iron in my house no matter how good the quality of the soldering because they are a potential fire hazard IMO if the tip fails and overheats.
