lately i have had to skip the conveinience of using my 225/150 ac dc stick welder which is at the table, to go and unroll the leads on the dialarc 250, i use the buzz box on little/small work. problem is that each time a scratch a rod, it will or want to stick. mostly with the 3/32 size, up into the higher heat range for 1/8 it is ok. the machine is about 15 years old, this is a new issue with this welder, it has worked fine since i bought it. i have good leads, good connections on both leads, good power supply, i have cleaned the inside and adjusted it as instructed by the manual. is the old girl getting tired or am i missing something else, that i can do to help her out. thanks
