5.3 Operation
1)
After being installed according to the above method, and the power switch being switched on, the
machine is started with the power LED on and the fan working.
2)
Pay attention to the polarity when connecting. There are two connection modes for DC welder in
general, one of which is straight polarity in which electrode holder is connected to negative pole and
workpiece is connected to positive pole, the other is reverse polarity to which is opposite.
Phenomena such as unstable arc, spatter, and electrode sticking could happen if improper mode is
selected. Exchange the quick plug to change the polarity if necessary.
3)
Select cable with larger cross-section to reduce the voltage drop if the secondary cables (welding
cable and earth cable) are long and distance between workpiece and welder is far.
Preset the welding current according to the type and size of the electrode, clip the electrode and then
welding can be carried out by short circuit arc ignition. For welding parameters, please refer to the below
table.

The following operation requires sufficient professional knowledge on
electric aspect and comprehensive safety knowledge. Operators should be
holders of valid qualification certificates which can prove their skills and
knowledge. Make sure the input cable of the machine is disconnected from
the electricity utility before uncovering the welding machine.
