I have an opportunity to purchase a DC machine w/o the High Frequency. I
also have an opportunity to purchase a separate High Frequency attachment.
Since my welding is only hobbist, would I need the High Freq for 'Straight
Polarity DC'? The DVD I purchased only showed using the High Freq with AC.
I imagine the High Freq makes starting any bead easier.
Off subject question...why in the devil are 'foot pedals' so darn expensive?
thanks. . charlie
