Before connecting, preparing or using
equipment, read Section 1: Safety Precautions.
4.1 CONNECTING THE EQUIPMENT TO
THE MAIN SUPPLY
The equipment is shipped without an installed
plug.

for carrying the amps indicated on the data plate.
For the A 250 AC/DC, install a #8 or larger input
power cord to the internal connections indicated in
section 4.5. Use a plug that is suitable for carrying
the amps indicated on the data plate.
Check to ensure that the power outlet is equipped
with a fuse that is capable of carrying the amps
indicated on the data plate of this unit.

4.2 SELECTING A LOCATION

Special installation may be required
where gasoline or volatile liquids are present
(See NEC Article 511 or CEC Section 20). Do
not move or operate this equipment where it
could tip over. When selecting a location for
this equipment, ensure that the following
guidelines are followed.
1. Use data plate to determine input power
requirements.
2. The operator must have unobstructed access to
all controls and equipment connections.
3. Do not position equipment in small, closed

trodes that use DCEP (Reverse Polarity) weld-
ing current. Reverse the connection for welding
electrodes that use DCEN (Straight Polarity)
welding current.
AC MODE
