Preparation For Welding Works - Lincoln Electric Compact 220 Operating Manual

- In case an excessive overheating is stated or smoke or fire is ob-
served as well as when the smell of burnt insulation is noticed and
an excesive trembling, vibrations or noise take place the operation
of the machine must be stopped and detailed survay or in case of
necessity a test of technical state must be carried out.
- The same refers to a situation when interlocking of current circuit or
a voltage on the cabinet is stated.
- In case of mechanical damage e.g. after a fall of the welder from
a considerable hight follow as above.
- Too high humidity may lead to the deterioration of the state of insu-
lation of the machine and can create electric shock hazard.
- During the operation some of internal parts of the welder get hot. Their
temperature can reach up to 100 C - it is normal and the machine is
protected against overheating by means of the temperature limiter.
- Too high temperture should not occure in connection contacts and
if the contacts get very hot it is a sign that their condition is bad.

Preparation for Welding Works

- Connect the return welding cable to the welding piece by means of the
clamp.
- Connect the shielding gas cylinder to the gas input through thereducer.
- Connect the mains cable of the welding machine to the mains socket of
an one-phase network 240V, 50Hz.
- Switch the machine on by means of the selector
ply indicator lights.
- Insert the electrode wire.
- Choose suitable settings of welding parameters according to the select-
ing mode and thickness of welding elements.
- Select the range of the welding voltage by means of the selectr
- Adjust the welding current by means of the knob of the electrode wire
feed speed control
- Obeying the appropriate rules you can begin to weld.
