Maintenance (Continued)
PROCEDURE
Check safety valve
Inspect air filter
Drain tank
Check pump oil level
Change pump oil
Oil leak inspection
Inspect drive belt
Check drive belt tension
Check pulley/flywheel alignment
Check for unusual noise/vibration
Check for air leaks
Clean air compressor exterior
Remove tank from service
*To check for air leaks apply a solution of soapy water around joints. While air compressor is pumping to pressure and after pressure
cuts out, look for air bubbles to form.
**The pump oil must be changed after the first 20 hours of operation. Thereafter, when using full synthetic non-detergent air compressor
oil, change oil every 100 hours of operation or once a year whichever comes first.
+Perform more frequently in dusty or humid conditions.

Welding Guidelines
GENERAL
This line of welding machines utilizes a process known as Shielded Metal-Arc Welding
(SMAW). This process is used to bond metals by heating them with an electric arc created
between the electrode and the work piece.
Electrodes used for shielded metal arc welding have two parts. The inner core is a metal rod
or wire that should be similar in composition to the base metal. The outer coating is called
flux. Various types of flux exist. Each coating is used for a particular welding situation.
While the metal is molten, it can be contaminated by elements in the air. This contamination
could weaken the weld. The flux coating creates a protective barrier called slag that protects
the molten metal from contaminants.
When current (amperage) flows through the circuit to the electrode, an arc is formed between
the end of the electrode and the work piece. The arc melts the electrode and the work piece.
The melted metal of the electrode flows into the molten crater and forms a bond with the
work piece as shown in Figure 7.
NOTE: Discontinue using and discard electrodes that burn down to 1 to 2 inches from
the electrode holder.
