DUTY CYCLE

The maximum output rating of this welder is at a 35% duty cycle.
Duty cycle is based on a ten minute period. Therefore, the welder
can be operated at the maximum rated output for 3.5 minutes out
of every 10 minute period without overheating.

OUTPUT CONNECTIONS

With the machine power switch off, the output leads are
connected to the output terminals marked "–" and "+". They are
located at the lower right and lower left corners of the front panel.
Strain relief for the electrode and work cables is provided by
routing the leads through the rectangular holes in the base before
the connections to the output terminals are made.
The recommended output cable sizes can be found in the Table
below.
