time to get started

[Shorty]

Well after about 2 years pondering over the idea of starting a roadster I have finally got started.
Big thanks to Handy Andy for doing me a chassis kit and I must say is excellent quality and all sizes and angles are spot on, you don't actually realized how many different angles need cut until actually getting started and will definitely save time and money if you don't have the gear to cut the steel. Also thanks for answering all the questions I had about various parts of the build.
Got started but seem to have a problem with my welder, ok for tacking together but the wire speed is all over the place, sometime works sometimes not. If any of you guys know anything about welders its a Clarke 150te, I'm guessing it needs new PCB.
Started tacking up chassis today an got to where the sb1's need welding together so just stopped there as welds are messy with random wire speed.
What is the best way to weld them together? I was thinking around 4 2" long welds each side or does full length need welding?
I will sort out a build thread eventually but still need to figure out how to upload pics
