This ENGEL heat cutter is designed for intermittent operation, and should not be used for more than twenty minutes at a time without pausing. The blade takes 6-8 seconds to heat up. Heat can be approximately controlled by using the on/off action of the trigger switch. The HSG 0 is best suited for cutting awnings, filter cloths, sail material, as well as synthetic strings and ropes. Figure (A) shows the unraveling which occurs when certain fabrics are cut mechanically. Figure (B) shows the result when the same fabric is cut and sealed with an ENGEL Heat Cutter. The HSG 0 (Blade not included) can be equipped with blades as well as the SF cutting foot. 90 Watt capacity, 110 Volt.
