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.

Setting Up for Additional Machine Accessories
Spool Gun
NOTE: Spool Gun is not included in the package.
□ Double check the MIG mode (K) is selected.
□ Double check the MIG gun/spool gun switch (U) is set to MIG gun.
□ For the shielding gas hose on the spool gun, pass through the hole
for gas hose (F) and connect to the shielding gas connector (T) on
the welder.
□ Connect the remaining two cables on spool gun to the gun cable
socket (G) and MIG gun/spool gun control socket (I).
□ 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.
