FIRE PREVENTION

WARNING: Failure to protect combustible materials against

welding sparks, hot slag and hot spatters can cause fire and

even explosion. Fire and explosion can cause death, injury

and property damage. To reduce the risks, please read,

understand and follow the safety instructions.

□ Check the area before welding. Ensure the work area is

checked and cleared of combustible and flammable

materials. A minimum distance of 35 feet (10 meters) is

required between work area and combustibles because 35

feet is an average distance welding sparks and slags can fly.

If the minimum 35 feet distance requirement cannot be met,

protect consumable/flammable materials with fire resistant

covers or shields.

□ Do not weld or cut on or near materials with combustible

coating or combustible internal substance, such as materials

in walls or ceilings, without any approved methods to

eliminate the hazard.

□ Do not weld or cut in areas (such as gas station) where the

air may contain flammable substances such as combustible

dust, gas, or liquid vapors.

□ Do not wear gloves, hair preparations, shoes and other

clothing that contains oil, grease, or other flammable

substances. Wear fire-resistant protective clothing to protect

upper and lower body against fire and heat. Protective

clothing includes but is not limited to leather gloves, heavy

long sleeve and cuffless shirts, heavy and cuffless pants,

high-topped shoes and helmet.

□ Do not dispose of hot slag in containers holding combustible

materials. Keep a fire extinguisher nearby and know how to

use it.

□ Follow requirements in OSHA and NFPA for hot work and

have an extinguisher nearby.

□ When finished welding, do not leave without a check for

evidence of potential fire. Overlooked smoke or flame have

risks to cause fire hazard. Check and make sure the welding

areas are free of sparks, slags, and flames before leaving

the welding area.

USE AND CARE

□ Ensure you choose the right welder model and welding

mode recommended for your application. Use the welder

and accessories in compliance with these instructions.

Operating a welder under improper conditions could cause

unpredictable safety issues.

□ For welding set up with spool gun, please follow instructions

“Setting Up for MIG/flux core Welding,” and exclude the portion of

“Installing the Wire Spool” and “Setting Up for Welding.”

Foot Pedal (adjust amperage)

□ Double check the TIG mode (K) is selected.

□ Connect the foot pedal to the MIG gun/spool gun control socket (I).

□ For welding set up, please follow instruction mentioned in

“Setting Up for LIFT TIG Welding.”

□ Use foot pedal to fine control amperage.

Maintenance

□ Before each use, inspect the general condition of the welder. Check for loose screws, cracked or broken parts, damaged circuit wiring

or cables, and any other potential risks that may cause safety issues. Replace damaged or worn parts, cords/cables or gun assembly.

□ After each use of the welder, clean external surfaces of the welder with clean cloth.

□ Periodically clean the welder using compressed air to blow out all dust and debris from the interior. If necessary, use compressed air to

clean the liner, especially when changing wire spools.

□ If the unit continuously shuts down due to thermal overload, please turn off the welder and have a qualified electrician inspect the

welder and repair it.

□ Store the welder and accessories in a clean and dry location out of reach of children.

□ Wire feed drive rolls are consumable accessories. The grooves of the drive roll will wear deeper after long-time usage. The wear out

will cause a contact between the idler roll and the drive roll. In this situation, the wire feed drive roll should be replaced.

□ Use a wire brush to scrub the outside of the contact tip. Use a tip cleaner (sold separately) to clean the inside.

□ Contact tips are also consumable accessories. After long-time usage, the worn round hole of the contact tip will turn to an elliptical

shape or form some bulges. Thus, replace the contact tip when it wears out.

□ Nozzle must be cleaned periodically because spatter and slag will build up inside the nozzle during welding process.

Troubleshooting

NOTE: When yellow tripped protection/alert indicator turns on, the possible causes are 1) tripped overheat protection; 2) short

circuit alert; 3) tripped overvoltage protection; 4) overcurrent alert; 5) MIG gun switch issue alert; 6) wrong input voltage alert.

Please refer to a qualified electrician to check your welder.

Problem

Possible Cause

Solution

No welder output when

switched on and neither

indicator LED is

illuminated

□ Loose ground clamp connection.

□ Check and make sure the ground clamp is well attached

to the workpiece.

□ No input power supply.

□ Check and make sure welder is plugged in.

□ Verify outlet output power.

□ Check the circuit breaker to see whether it is tripped or

not. Reset if necessary.
