MB25 to MB15 conversion

[martinez]

I use MB15 torches on my welder but have a couple of new MB25s off fleabay and wondered if I can covert these to MB15 by changing some bits on the torch ? I find the 25 torches too big for most of what I do

Would it not be easier to just buy a MB15 torch? Other than the plastic handle, there are often no common parts.

I'd put them back on ebay, and use the proceeds to get a mb15
Or get used to the size of the 25.

to be honest, I don't mind buying off ebay, but selling stuff is too much hassle. Just wondered if I can swap the head of the torch for smaller 15 bits and make them more usable, I've already got a couple of 15s anyway, but one of the 25s is a 4mt parweld and all my others are 3mt. Well if there's nothing available guess I can make/modify something on the lathe

You could have a go but do it at your own risk, Why not advertise them here for sale and just buy the right torches, surely you must of known that they were bigger when you bought them

Make for make there doesn't seem that much differance in size between the two.

If you fit a long conical (15mm i/d) shroud to a MB25 then it boils down to a very slightly stiffer lead.

I have both for my Lincoln 210 (185 amp), and use the MB25 all the time.

aha, well it's the size of the nozzle/shroud that's the issue really it doesn't get into those important little places, so I can get a smaller one and job's a goodun then ?
I thought maybe you could change the swan neck etc or the fitting for the tip and then use MB15 parts

Look for bottleneck shrouds/nozzles
