Location
Selecting the proper location can significantly increase performance, reliability and life of the arc welder.
•For best results locate the welder in an environment that is clean and dry. Avoid locations exposed to high temperature, high humidity, dust and corrosive fumes. High humidity causes moisture condensation on electrical components. Moisture can contribute to corrosion and short electrical components. Dust and dirt in the welder retain moisture and increase wear of moving parts.
•Place the welder in an area that provides at least twelve inches
(305 mm) of ventilation space at both the front and rear of the unit.
Keep all obstructions away from this ventilation space.
•Store electrodes in a clean, dry location with low humidity to preserve the flux coating.
•The welder control panel contains information regarding proper input voltage and amperage. Follow the specifications on the welder front panel.
•The receptacle used for the welder must be properly grounded and the welder must be the only load on the power supply circuit. Refer to the Circuit Amps chart under Specifications for correct circuit capacity.
•The use of an extension cord is not recommended for electric arc welding machines. The voltage drop in the extension cord
may significantly degrade the performance of the welder.
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:
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 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. 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
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 Setting |
Diameter | (Amps) |
3/32 inch (2.5 mm) | |
1/8 inch (3.2 mm) | |
5/32 inch (4.0 mm) |
The electrode 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.
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 20% duty cycle, actual welding can occur for two minutes, then the welder must cool for eight 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.
