Maintenance (Continued)
STORAGE (Continued)
Use of fuel stabilizers or anti-gumming agents in the fuel system
can help prevent the build up of gum and varnish.
Whenever the unit is stored, be sure that the fuel shut-off valve is
in the closed position.
Refer to the engine manual that accompanies this unit for
instructions regarding maintenance of engine components.
The Engine is factory set to 3800 RPM with
NO load. Never tamper with engine speed
settings or frequency settings. Any governor adjustments should be
made by qualified personnel only.

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 4.
NOTE: Discontinue using and discard electrodes that burn down to 1 to 2 inches from
the electrode holder.

WELD CABLES
1.
Check condition of weld cables and immediately repair or
replace any cables with damaged insulation.
2.
Check condition of electrode holder insulating pieces and
immediately replace cracked or missing parts.
EVERY 3 MONTHS
Replace any unreadable labels on the unit. Use compressed air
to blow all dust and lint from the ventilation openings.
