Operating Instructions
(FRONT PANEL SWITCH MUST BE SET TO welder Position)
Welding Lead Assemblies
Welding leads assemblies are not included with all units. Use copper welding cables in the size specified in Table 3.
1.Verify that the surfaces of metals to be joined are free from dirt, rust, paint, oil, scale or other contaminants. These
contaminants make welding difficult and cause poor welds.
All persons operating this equipment or in the area while equipment is in use must wear
protective welding gear including: eye protection with proper shade (minimum shade 10), flame resistant clothing, leather welding gloves, and full foot protection.
If heating, welding, or cutting materials that are galvanized, zinc plated, lead, or cadmium plated
refer to the General Safety Information Section for instructions.Toxic fumes may be created when these materials are heated.
2.Connect the work clamp to the work piece. Make sure the contact is on bare metal and not obstructed by paint, varnish, corrosion, or
3.Insert the exposed part of the electrode (the end with no flux) into the jaws of the electrode holder.
4.Set the amperage adjustment knob to the proper amperage for the electrode diameter. Refer to the electrode
manufacturer for proper current settings.
The electrode holder and rod are electrically “live” (current potential) when the engine is
running.
5.Position the electrode to begin weld, lower the welding helmet or position the hand shield, and strike an arc. Adjust weld amperage as needed.
6.When finished welding, turn engine off and store unit properly.
Duty cycle /thermostatic protection
Welder duty cycle is the percentage of actual weld time that can occur in a ten minute interval. For example, at a 10% duty cycle, actual welding can occur for one minute, then the welder must cool for nine minutes.
Internal components of the alternator are protected from overheating with an automatic thermal switch.
Before starting the compressor, thoroughly read all component instructions manuals, especially
the engine manual.
1.Set compressor switch to ON. The compressor clutch will engage and the pressure switch will disengage the clutch when the tank pressure reaches the preset maximum pressure. As air is discharged from the tanks and the tank pressure falls to the preset minimum pressure, the pressure switch will engage the clutch again.
2.Adjust the regulator knob to vary the outlet pressure according to the requirements of the tool(s) being used.
3.Connect air hose(s) to outlet connector(s) and connect tool(s) to hose(s).
4.An ASME safety valve in the manifold will automatically release air if the tank pressure exceeds the preset maximum.
5.The discharge tube carries compressed air from the pump to the check valve. This tube becomes very hot during use. To avoid the risk of severe burns, never touch the discharge tube.
6.The check valve allows air to enter the tanks, but prevent air in the tanks from flowing back into the compressor pump.
7.There is a drain valve in the end of each tank. They have weighted tubes to draw air/liquid from the bottom of the tanks. Use these valves to drain moisture from the tanks daily to reduce the risk of corrosion. Reduce tanks pressure below 10 PSI, then drain the moisture from the tanks daily to avoid tank corrosion.
Drain liquid from tank daily.
8.All lubricated compressor pumps discharge some condensed water and oil with the compressed air. Install appropriate water/oil removal equipment and controls as
necessary for the intended application.
Failure to install appropriate water/oil removal equipment may result in damage to machinery
or workpiece.
Do not attach air tools to open end of the hose until startup is complete and the unit checks
okay.
Moisture in compressed air
Moisture in compressed air will form into droplets as it comes from an air compressor pump. When humidity is high or when a compressor is in continuous use for an extended period of time, this moisture will collect in the tank. When using a paint spray or sandblast gun, this water will be carried from the tank through the hose, and out of the gun as droplets mixed with the spray material.
Important: This condensation will cause water spots in a paint job, especially when spraying other than water based paints. If sandblasting, it will cause the sand to cake and clog the gun, rendering it ineffective.
A filter or air dryer in the air line, located as near to the gun as possible, will help eliminate moisture.
