This All American is a basic heavy duty outfit with all the necessary components for industrial and commercial applications including cutting, brazing and welding. Optional equipment may be added as needed. RV80 Heavy Duty Series Regulators incorporate a durable stainless steel diaphragm, an accessible rear loaded seat assembly, and easy-to-read single scale brass cased 2½" gauges. Our CA43 Cutting Attachment with its universal multi-gas head mixer allows for flexibility in most industrial applications for acetylene 3 PSIG and above and for most fuel gases 5 ounces and above with proper tip and regulator. The 43L9E Welding Handle has a durable two tube silver brazed construction and ergonomically designed ribbed outer handle that is vented for safety.
