Well I preaty much understand all things you spoke to me.
Backside od that story is that I live in a very poor country. For the simple egzample... one small hoby mig welder(30-160A 0.6 to 0.8 wire) costs same money amount as my old car+my arc welder. It is abouth the same equivalent as my 2 mounts salary.
And one MIG welder I could aford for 2 mount of hard work only in case that in those 2 mounts I do not eat and drink anything, do not pay taxes, do not pay electric and wather and phone and internet bils...
So a MIG welder is curently realy unaviable to me...
Must fight with this telwin welder until better days will come, and if they dont...will dye burning rods like old school welding gangsta
Talking abouth thinn rods... i can buy 1.6 2 2.5 3.2 4 5 mm rods here. and did tryed all of them. Problem is welding current. my welder goes from 160 to 55 amps. and on lower amperage it is much unstable. its realy hard to get arc going on 55 amps. althought i can manage that to.
simple thing is happening 55amps is way to much on 1.6 and 2mm rods. they do not stick and arc goes easy buth it brings way to much heat on metal.
beleave me or not...i do have less burntrought with 2.5mm rods and 80 to 85 amps than with 1.6 rods on 55 amps.
So...It is a in this moment only solution for me to use bigger rods like 2.5mm and 80 amps curent. that curent is just slighty enought to melt the rod buth not to much heat goes on sheet metal and it does not burns trought.
on the other hand using 55 amps and 1.6mm rods I just end with my sheet metal foll of holes like some swiss chese
