4. Store idle equipment. When not in use, tools must be stored in a dry location to inhibit rust. Always lock up tools and keep out of reach of children. 5. Do not force tool. It will do the job better and more safely at the rate for which it was intended. Do not use inappropriate attachments in an attempt to exceed the tool capacity. 6. Use the right tool for the job. Do not attempt to force a small tool or attachment to do the work of a larger industrial tool.
If there is any doubt, do not operate the tool. 19. Maintenance. For your safety, service and maintenance should be performed regularly by a qualified technician. 20. Use proper size and type extension cord. If an extension cord is required, it must be of the proper size and type to supply the correct current to the tool without heating up. Otherwise, the extension cord could melt and catch fire, or cause electrical damage to the tool.
6. Avoid fire and explosion. Remove flammable and explosive material from at least 35 feet from the welding arc to prevent welding sparks or molten metal from starting a fire. Keep a type ABC fire extinguisher within easy reach. Thoroughly clean the object being welded of any paint, grease, or other foreign material. 7. Avoid being burned. Always wear ANSI approved welding gear: leather gloves, leather apron, and shoes. 8. Wear proper clothing when welding. Use flameproof, welding type gloves.

While holding the Welding Torch handle, with the electrode wire clearly out of the way of any grounded objects, turn the On/Off Switch to the ON position. 6. Momentarily press the Welding Torch trigger switch to test the wire feed speed. Adjust the speed by turning the Wire Feed Speed Control knob. 7.
Troubleshooting Symptom MIG Welder does not work when turned on. Wire does not feed properly. Reduced welding power. Possible Cause Checks and Remedies No power to MIG Welder. Check Line Cord and plug. Check facility circuit breaker. Overheated during use. In overload mode; Allow to cool down. Insufficient wire feed spring tension. Tighten spring tension knob. See photo on page 6. Wire guide sheath blocked. Clean or replace wire sheath. Wire spool axle nut too tight.
2. Store the unit in a clean and dry location. 3. Periodically clean out the Torch Head.
