Introduction; Installation And Operator Instructions - Lincoln Electric Saf-Fro DIGISTEEL 255C Manuel D'utilisation

SAFETY MARK: This equipment is suitable for supplying power for welding operations carried out in
an environment with increased hazard of electric shock.
CYLINDER MAY EXPLODE IF DAMAGED: Use only compressed gas cylinders containing the
correct shielding gas for the process used and properly operating regulators designed for the gas and
pressure used. Always keep cylinders in an upRight position securely chained to a fixed support. Do
not move or transport gas cylinders with the protection cap removed. Do not allow the electrode,
electrode holder, work clamp or any other electrically live part to touch a gas cylinder. Gas cylinders
must be located away from areas where they may be subjected to physical damage or the welding
process including sparks and heat sources.
The manufacturer reserves the Right to make changes and/or improvements in design without upgrade at the same time
the operator's manual.

Duty cycle and Overheating
The duty cycle of a welding machine is the percentage of
time in a 10 minute cycle at which the welder can operate
the machine at rated welding current.
Example: 60% duty cycle
Welding for 6 minutes.
Excessive extension of the duty cycle will cause the
thermal protection circuit to activate.
4
Break for 4 minutes.
