AC Output Connections

This welder has two AC outlet plugs that are clearly marked with the electrode and ground clamp
symbols. 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.
NEVER REVERSE CABLE CONNECTIONS AS THIS COULD CAUSE INJURY TO THE
USER AS WELL AS DAMAGE TO THE EQUIPMENT.

DC Output Connections

If you have purchased the 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 ensure the best
possible connection. The open circuit voltage of the DC connectors is approximately 72 Volts.

Adjusting Amperage

To increase the amperage, simply crank the amperage adjustment handle on top of welder clockwise.
As you crank the handle you will see the amperage indicator located in the sight glass on the amperage
setting scale move upward increasing the amperage. Stop cranking when you have reached the
desired amperage range.
To lower the amperage, simply crank the amperage adjustment handle on top of welder counter
clockwise. As you crank the handle you will see the amperage indicator located in the sight glass on the
amperage setting scale move downward. Stop cranking when you have reached the desired amperage
range.
NOTE: Be sure that the amperage adjustment handle is secured properly and that the screw and nut are
tight. Failure to do so will result in the inability to adjust amperage. Also be careful not to over tighten
the connections which could result in damage to the unit.

Learning to Weld

The self taught welder learns through a process of trial and error. The best way to teach yourself how to
weld is with short periods of practice at regular intervals. All practice welds should be done on scrap
metal that can be discarded. Do not attempt to make any repairs on valuable equipment until you have
satisfied yourself that your practice welds are of good appearance and free of slag or gas inclusions.
What you fail to learn through practice will be learned through mistakes and re-welds later on.
