⚠WARNING Fumes and Gases Do not use unit in the presence of gasoline, diesel, propane, or other flammable liquids. Sparks created from this unit may ignite liquids or fumes, causing an explosion and serious injury or death. Fumes emitted from the welding process displace clean air and can result in injury or death. ...

explosive materials. Do not operate any electric arc welder in areas where flammable or explosive materials are present. Remove all flammable materials within 35 feet of the welding arc. Take precautions to ensure that flying sparks do not cause fires or explosions in hidden areas, cracks, or areas you cannot see.

Keep high-frequency source doors and panels tightly shut, keep spark gaps at correct setting, and use grounding and shielding to minimize the possibility of interference. ARC WELDING can cause interference! Electromagnetic energy can interfere with sensitive electronic equipment such as computers and computer-driven equipment such as robots.

⚠CAUTION Make Tight Connections Improper connections, including loose connections, in the weld circuit leads to resistance causing excessive heat and may result in damage to your equipment. Insure all connections are snug and tight. Page 14 of 27...
Engine Fueling And Lubrication Make certain that the engine has been properly fueled and lubricated prior to operation. Refer to the engine operator’s manual. Setting Amperage Turn the Amperage Control until the desired welding amperage. Approximate Amperage Ranges Electrode Diameter Amperage 40 –...
Operating Instructions ⚠WARNING High voltage danger from power source! Consult a qualified electrician for proper installation of receptacle at the power source. This welder must be grounded while in use to protect the operator from electrical shock. If you are not sure if your outlet is properly grounded, have it checked by a qualified electrician.

ii. The bead will undercut the work. The bead will be flat and porous. iii. iv. The rod may be freeze or stick to work piece. Note: The rate of travel over the work also affects the weld. To ensure proper penetration and enough deposit of the rod, the arc must be moved slowly and evenly along the weld seam.
Page 19
It is important that the gap be maintained during the welding process without being too wide or too narrow. If it’s too narrow, the rod will stick to the work piece. If it’s too wide, the arc will be extinguished. Practice will be needed to maintain the gap. A beginner will usually have sticker or arc extinguishing.

more toward the metal above the weld joint. This more direct angle helps prevent the weld puddle from running downward while still allowing slow enough travel speed to achieve good penetration. A good starting point for your electrode angle is about 30 degrees DOWN from being perpendicular to the work piece.
After Each Use ⚠CAUTION Hot Materials - Welded materials are hot and can cause severe burns if handled improperly. Do not touch welded materials with bare hands. Do not touch the torch nozzle after welding until it has had time to cool down. 1.
Maintenance Interval Maintenance Point Inspect all warning and caution labels affixed to this unit. If they are worn, torn or otherwise unreadable, replace the warning labels. Every 3 Months Inspect and clean and tighten all weld power connections. Maintain Your Engine Refer to the engine manual for routine maintenance on the engine.
