WARNING
Avoid the risk of electric shock or severe injury. When the power cable gets damaged
it should only be replaced by the manufacturer or at a
The build quality of the electric insulation is altered if spills or liquid gets into the tool while in use.
Do not expose to rain, liquids and/or dampness.
Before gaining access to the terminals all power sources should be disconnected.
WARNING

Power requirements

WARNING • The welding machine shall be perfectly grounded before
operating and ground shall not be disconnected before finishing the welding job;
otherwise the operator may receive an electric shock and get severely injured.
• There shall be a parallel connection when the tool is using the same ground
together with other tools. Never connect a series of devices.
• The gauge in the ground conducting cable cannot have a lower

gauge then the power cable.
CAUTION • The connection to the power source shall be carried out by a
professional electrician and should follow the electric diagram shown to the right.
• Double-check that the input connection
CAUTION
voltage shown in the welding machine nameplate matches with
the voltage in the power source (220 V or 110 V). The connection
screws shall be tightly fastened.
CAUTION • The cord gauge in the power source shall
meet the following requisites:
Switch
Power cord
* The fuse fusion current is double of its rated current.
If extensions are required between the welding machine and the
work piece, the welding cord gauge shall be increased in order to
keep the welding machine energy output with a potential drop not
higher than 4 V
