Cutting thick material
There are several important Factors to consider when cutting material that is 100 mm (4 in.) thick or greater:
• Torch position: The torch should be positioned just beyond the edge of the plate for best results in attaching the arc
to the full edge of the plate
• Motion delay: Provide sufficient motion delay to allow the arc and molten material to extend down the majority of the
cut edge prior to beginning torch motion
• Reduced cut speed: A reduced cut speed may be necessary at the start and at the end of the cut to ensure the arc
fully penetrates the entire thickness of the plate
• Cornering: A reduced cut speed or a dwell may be necessary when cutting corners of 90 degrees or less to
maintain optimum edge flatness
• Edge quality: To improve edge flatness when cutting materials over 100 mm (4 in.) with the 800 Amp H35/N
