Hi all,
I just joined up but have been reading a bit on here about MIG welding, gas, welders etc.
I'm not a welder but I guess a hobbyist. Anyway, after much deliberation and some financial quandary, I ended up buying a Röhr MIG-200MI from Amazon, I then went through the ringer with disposable bottles, gave up and bought a 10l 200bar Tri-mix bottle and rigged it all up.
I had been doing a bit of stitch welding and rust repair to my race car and the progress caught the eye of a local race car company who asked if I wanted some steel to practice on... I couldn't say no!
So as with everything, the catch was that if my welds were good, they'd like me to put together a gearbox trolley for the quick removal and replacement of the gearboxes on one of the LMP racecars they are currently building.
How could I say no!?
So here it is, the only spare stock steel they had was pretty manky, covered in millscale and light surface rust. The flap wheel and grinder made it look a bit better but still tricky. I'll just post a few pictures up now and await the roasting lol.
As I say, never done anything like this before but I'm proud of my achievements. The trolley isn't complete year. A 2mm thick sheet is needed on the top and some securing screws will be installed to ensure the gearbox doesn't move around once on the trolley and removed from the car. The trolley was put on a level setup platform and I managed to achieve a 0.1mm wobble and the top was 0.07° out of line with the base. To rectify this, we put washers in between the trolley and one caster, this bright it perfectly level with the gearbox base.
I'm quite pleased with it and can't wait to get back to finish the top and then get it powder coated.
Any tips, tricks or advice always welcome.
As for setup... The Röhr held up to the job well. The metal was 2.5mm box so I set wire speed to 4, Voltage to 7 and the gas was set to 60psi and 15L/min. It seemed to do well. I'll have to measure the wire speed etc won't I as I just realised the setting won't relate to anything that could be referenced to another welder lol.
