hi I have a boc 190c mig welder single phase. I have just had a new 6mm swa cable wired up to my garage with a 16amp socket fitted for the welder. The problem is I can't run it on full power or it trips the breaker. It was wired to a b16 amp and because that didn't work my electrician fitted a b32 amp and it still trips. Why is this happening? The welder has 8 power settings and it even tripped on the 16amp breaker on setting 7. Setting 7 works fine on the 32amp breaker. Any advice on this subject would be grateful.
