This is my $10 eBay flex head torch. The torch supplied with the welder was too thick with the start button on it and I didn't use the button anyway. The flex head allows you more choice of angle without getting your hand too uncomfortable.
It has a #7 nozzle with a gas lens that allows me to use the electrode further out. Electrode is 2.4mm zirconiated.

The foot pedal supplied is a cheapie. You could probably make one similar from junk in the shed and gets a 10k linear pot from Jaycar.
It only has 40mm travel to go from 0 to 200 amps so not easy to get accurate settings.
To compensate for this I added another 10k pot in a plastic box and put it in line close to the machine so I can adjust it easily. I can now set max amps down to as low as 45 so the pedal is much more precise.
Cost about $10 in parts.

It's also not as hard to learn as some would have you believe if the put the effort into learning.
