Spot Welding; Storage And Transportation - Lincoln Electric Compact 220 Operating Manual

Spot Welding

The welding machine Compact 220 can use to spot welding. The spot wel-
ding process is recommended to join thin elements e.g. sheet metal.
For this you must replace the nozzle with a special one, which is equipped
with pins. Those pins enable to tighten joining elements and free flow of the
shielding gas.
Recommendation:
- Set the welding parameters as above.
- Quality of the welding seams depend on the welding time.
- Too long the welding time may cause smelting of the material.
- Too short the welding time may cause no connection.

Storage and Transportation

- The welding machine should be stored in close rooms featering temperatu-
res ranging from -10 C to +40 C and relative humidity up to 80 %.
- The room should be free of caustic, conducting dust and other environ-
mental agents.
- It is recommended to store welders in their packagings.
- Transportation inside the factory can be carried out by using own chassies
of the machine provided the roads are rather smooth and at low speed up
to 5 km/h, optionally a crane or an overhead traveling crane can be used.
- For transportation on longer distances the welder should be packed in
the way protecting it against mechanical damages.
- For transportation any means of transport can be used.
- During the transport welding machines should be placed along the moving
direction and protected against rolling or moving as well as against preci-
pitations.
