Protective clothing is available in flame-retardant materials.

*Use welding screens to protect others from exposure to IR and UV rays

6.1Work Piece Cleaning before Welding

Clean the weld groove and surrounding area of rust, grease, dirt and paint before welding. It is essential to have a clean weld area for the MIG process.

6.2 Adjustment and Test before Welding

*The cooling fan indicates that the switch is on.

*The cylinder valve must be open before the gauges will indicate information.

*To adjust gas flow, open the valve of gas regulator (rotate clockwise), disengage drive roll idle arm, press torch trigger and adjust gas flow to meet the welding requirements.

*Make sure wire is in the correct drive roll groove, tighten idle arm on drive system, adjust wire feed speed to #10, remove contact tip, straighten torch, press torch trigger and feed the wire to torch head. WARNING: do not look into the end of the torch as wire coming out the end of the gun could damage your eyes or other facial features.

*The wire feed speed should be consistent. If it is not, check the drive roll tension. Proper adjustment will result in even flow of wire.

*When flux-core welding, over-tightening the drive roll arm can cause damage to the wire and affect smooth wire feeding.

6.3 Welding

*Check parameter chart for initial setting of the voltage and wire feed. Adjustment may be necessary for your application and style of welding.

*Warning: Do not adjust the voltage setting while welding. MIG gun trigger must be released.

6.4 Maintenance and Service

*Proper maintenance and service are required to assure proper performance and prolong the life of your welder. Normal wear items include: MIG gun components (i.e., contact tips, nozzle, adaptor, liner, drive rolls, gas hose, and contactor).

*If used in a dusty environment, the internal components will need to be cleaned with high-pressure air. Cleaning is recommended annually unless used in high dust environments.

*Only qualified personnel are allowed to repair components that require the removal of the case. When in question, call the technical help number listed on the cover of this manual.

*This welder is designed for use and storage indoors or in a covered area at 10°F–105°F. If used outside it should not be exposed to rain or high humidity.

. * The ambient temperature range: when welding: -14°F–104°F

during transport or in storage: -13°F–131°F

*Relative humidity: when at 104°F: ≤50%, when at 68°F: ≤90%.

*Not for use in high vibration conditions.

*Do not use in the rain or other wet environments.

*Make sure all cable connections are tight to assure proper connections.

*Check shielding gas system for leaks around connections.

*If there is abnormal noise from moving parts turn off, unplug and take to a qualified repair center.

*Keep MIG gun cable as straight as possible when welding to reduce friction when wire is feeding through the

gun.
