I just acquired the above listed welding rods , 7018 H4R . What type of metal are the rods used for . Aluminum , steel , etc.. What minumum and maximum thickness that they are used for and what type of machine , as in AC Or DC or both . To look at them , I'd say at least a 220 VAC machine . Could they be used on a 120 VAC 75 amp. machine as that is the only stick welder that I have . I don't own a 220 VAC machine , yet anyway. They are about 18 inces long and about as big around as a no. 2 pencil . The powder was comming off of some of them . I'm therefore assuming that they got wet but not for sure. Can the powder just naturally fall of without them being wet ? I say that it could , but I'm no welder by no means . Well , anyway what is the spec. and requiements on these rods ? Thanks for any and all help .
Thanks ,
