Hi Arjen,
For relatively safe welding at home/outdoor, I suggest an inexpensive 110v
flux-core welder (no gas needed). Buy high quality wire to minimize splatter,
and go easy on the trigger at lowest setting for tubings. Do spot welding if
needed to control the heat on very thin tube.
If you have access to a shop with other methods, try them all which should be
strong enough for tubings, but differ in control, heat, beads, and safety
hazards. Here are some claims by Greenspeed:
The frame tubes are MIG welded. MIG beads are not as fine as TIG, though the
craftsmanship of the Greenspeed is exceptional. We don't see many MIG welded
recumbents, so we asked Ian about it, "We find that MIG welding puts less heat
into the tubing than TIG, and a lot less than brazing, leading to less of the
metal around the joint losing its strength. We have also had superior
performance from the MIG joints over brazed joints. In addition, we find that
the MIG is quicker than TIG, and much faster than brazing, thus is is much
better suited for production work". http://www.greenspeed.com.au/rdtest1.html
Enjoy,
Vi
