Weight includes torch & leads, input power cord,
and work cable with clamp.
CAUTION
Provide clearance for proper air flow through
the power supply. Operation without proper
air flow will inhibit proper cooling and reduce
duty cycle.

2. Duty Cycle is the percentage of time the system can be operated without overheating. Duty cycle
is reduced if primary input voltage (AC) is low or the DC voltage is higher than shown in this chart.
3. Air supply must be free of oil, moisture, and other contaminants. Excessive oil and moisture may
cause double-arcing, rapid tip wear, or even complete torch failure. Contaminants may cause poor
cutting performance and rapid electrode wear. Optional filters provide increased filtering capabilities.
