• Finish jobs faster with cut speeds two and a half times greater than oxyfuel on 1/2" mild steel.
• Spend less time on grinding and edge preparation due to superior cut and gouge quality.
Easy-to-use for cutting and gouging
• No need to change the air pressure. Smart Sense™ technology ensures that it is always correctly set.
• Drag cut at full output with a patented shield that reduces dross buildup for smoother cutting.
• Tackle different jobs with multiple, easy-to-use torch styles.
Low operating costs
• Reduce costs with long consumable life and more uptime.
• High power efficiency lowers energy consumption.
Built and tested to withstand the harshest conditions
• Duramax® torches are designed for high-impact and heat resistance.
• SpringStart™ technology ensures consistent starting and a more reliable torch.
• Low maintenance for maximum uptime.
Professional-grade plasma metal cutting and gouging system for handheld cutting 1" and mechanized piercing 3/4".
