Need for woods nickel strike
I want to activate ss product for plating and I need info for Woods nickel strike.

A woods nickel strike consists of:
240 g/L nickel chloride.6 H2O
360 ml/L Hydrochloric acid
40-100 amps/sq foot cathodic. (Some references recommend reverse current then direct, however, reverse current leads to iron and /or chromium contamination and and early failure or adhesion or cause to discard the solution and make up new more frequently) I have found that good cleaning and acid treatment prior to the Woods strike works well.

May I know the current and contact time for the nickel strike? Normally, do we use high current, short contact time? How high is the current? time?
