I need your help about this question of burn back .
I am using a solid ferritic stainless steel on a robot. wire size 1.0 mm after about 2minutes of wedling the bead become narrow and we have a burn back .
does it come from the wire feeding ? less pressure on the roller , to much oïl on the wire and the rollers are slipping ?
or bad quality of tip which do not wear at high temerature
thanks in advance for your reply
best regards richard
happy new year !!!
