My mind has been blown! For the past 3 years I've been using a cheap crap arc welder I got from Aldi for £20 I can't fault it I've made tons of projects with it and it got me welding! Anyway I've just received the stinger for my r-tech 180 so gave it a go with some 3.2mm rods. My god it felt so much easier I got great welds straight away even a good t join witch is something I've struggled with. I pretty much touched the electrode on the work and it stuck an arc right away! No sticking was smooth just amazing! I just had to tell someone and my girlfriend could g be less impressed haha.
