MACHINE OPERATION

AC OUTPUT CONNECTIONS (FP-235 AND FP-235 AC/DC)

This welder has two AC outlet plugs that are clearly marked with the electrode and ground clamp symbols.
NEVER reverse cable connections as this could cause injury to the user as well
as the equipment!)
Connect the electrode output cable to the electrode connections and the ground cable to the ground connection.
These connections are Dinse type connections and require that they be twisted into place in order to insure the
best connection. A slight twist is fine. You are now able to weld with 30 to 235 Amps of AC Power. The
open circuit voltage of the AC connections is approximately 72 Volts.
injury from shock. Read, understand and follow ALL safety instructions. Be sure that
everyone who uses this welding equipment or who is a bystander in the welding area
understands and follows ALL safety instructions as well.
techniques should ALWAYS be present in the working area. If a person is uncon-
scious and electric shock is suspected, DO NOT touch the person if he or she is in
contact with commands. Disconnect power from the machine, then use First Aid.
Use dry wood or other insulating materials to move cables, if necessary, away from
the person.
DC OUTPUT CONNECTIONS (FP-235 AC/DC)
If you have purchased the FP 235 AC/DC Model, it has two DC outlet plugs marked DC+ and DC-. These
plugs can be connected in either the DC direct current position or in the DC reverse polarity position. The DC
connectors are Dinse type connections and require a slight twist in order to insure the best possible connection.
The open circuit voltage of the DC connectors is approximately 72 Volts.

SELECTING AC OR DC WELDING OUTPUT

The use of the proper type of welding current is determined by the type of repair that needs to be made.

AC CURRENT WELDING

Alternating current (AC) welding is performed when the welding cables are connected to the AC electrode and
ground jacks. This type of welding current is ideal for heavy plate steel in flat position welding.
Most AC welding operations will be general purpose work on mild steel utilizing AWS rated 6011 and 7018
type electrodes.
