Operation
1.Be sure to read, understand, and comply with all precautions in the General Safety Information section. Be sure to read the entire section entitled Welding Guidelines prior to using this equipment.
2.Turn welder off and plug into appropriate receptacle: 230v-50 amp
3.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
! WARNING operating this equipment or in the area while equipment is in use must wear protective welding gear including: eye protection with proper shade, flame resistant clothing, leather welding gloves, and full foot protection.
If heating,
! WARNING welding, or cutting materials that are galvanized, zinc plated, lead, or cadmium plated refer to the General Safety Information Section for instructions. Extremely toxic fumes are created when these metals are heated.
4.Connect the ground clamp to the work piece or workbench (if metal). Make sure the contact is secure, and not obstructed by paint, varnish, corrosion, or non-metallic materials.
5.Insert the exposed part of the electrode (the end with no flux) into the jaws of the electrode holder.
6.Set the amperage adjustment knob to the proper amperage for the electrode diameter. Refer to the following chart for proper electrode current settings.
Electrode | Current |
Diameter | Setting (Amps) |
| | |
3/32" (2.5 mm) | 60-110 | |
| | |
1/8" (3.2 mm) | 110-160 | |
| | |
5/32" (4.0 mm) | 150-230 | |

The electrode
! WARNING holder and rod are electrically "hot"(have current potential) when the welder is on. Grounding against any metallic surface may produce an arc which could cause sparks and damage eyesight.
7.Hold the electrode and holder away from the grounded work piece or workbench. Turn on the welder. A green light is illuminated when the welder power is on.
8.Position the electrode to begin weld, lower the welding helmet or position the hand shield, and strike an arc. Adjust weld amperage as needed.
9.When finished welding, turn welder off and store 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 this welder are protected from overheating with an automatic thermal switch. A yellow lamp is illuminated on the control panel
if the duty cycle is exceeded. Welding operations may continue when the yellow lamp is no longer illuminated.
Maintenance
Disconnect power
! WARNING supply and turn machine off before inspecting or servicing any components.
Before every use:
1.Check condition of weld cables and immediately repair or replace any cables with damaged insulation.
2.Check condition of power cord and immediately repair or replace any cord if damaged.
3.Check condition of electrode holder insulating pieces and immediately replace cracked or missing insulators. Verify that all fasteners are tight and insulated.
Do not operate this
! WARNING welding machine with cracked or missing insulation on welding cables, electrode holder, or power cord.
Every 3 months:
Replace any unreadable labels on the welder. Use compressed air to blow all dust and lint from the ventilation openings.
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.
