What size torch tip should be used to cut rusted steel?
A. We recommend to remove any rust. If you are cutting rusty iron, the BG will do it more reliably and with less spitting, popping and missed cuts than conventional fuel-gas. We recommend using ‘flush’ type tips. ‘Recessed’ tips will heat up because the flame will touch the metal. Assuming you are using the Victor brand of torch: Use a #0 torch-cutting tip for up to 1 inch of steel (sometimes thicker). A #2 tip should be good to cut at least 4 inches of steel which is the maximum recommended depth for the ER1200. Even then we recommend the extra capacitor option.
