ATTENTION:
For safety guarantee, only the person with operating
certificate or expert skills can collocate, check,
maintain, fix and repair the welder.
For safety guarantee, please completely read and
understand the details in this manual before using.
Keep the manual in convenient place for easy reading.

Comparing with other welding machines, CO2/MAG arc welding machine has the
following features：
◆Higher working efficiency : CO2arc has strong penetration ability, deeper
welding pool, higher melt efficiency. So, welding speed is faster and productivity is
1-3 times higher than stick welding
◆Lower welding cost : CO2gas can be easy and cheaply obtained from any
chemical or brewage factory, just 40～50℅cost of other welding machines
◆Wider application area: It can be used at any position. The thinnest limit
is 1mm and thickness almost no limit(multi-layer welding). Once thin sheet welding,
the speed is faster and distortion is less.
◆Stronger anti-rust ability, lower hydrogen percentage ,better anti-crack
ability.
Do not◆need slag-cleaning after welding, arc is easy control and observation.
Mechanization and automatization are easy realized.
At present, CO2gas welding machine is mainly used for dark metal welding, such as
low carbon steel alloy , low alloy steel and so on, it also can be used for stainless
steel welding with mixed gas or cored wire.

NOTICE
1、CHAEACTERS
Performance exceeding common SCR welding machine
No◆-remote control cable，enhance maneuverability，decrease cable broken
problem.
New design and tri◆-protection treatments，dust、water、smog protections，improve
performance and suitable to any worksite and environment.
Separately adjust for current and voltage /simple centralize conversion f◆unction，
whatever skilled or non skilled operator can use easily.
2、SAFETY ATTENTION
Following rules must be abided by to ensure operation safety
CAUTION! AVOID SERIOUS BODY INJURED ACCIDENT HAPPENING
precaution for grounding◆
should be let qualified electric person to connect grounding cable as per concerned
law and regulations
Usage of protection cloth◆、protection appliance
should use protection appliance in order to avoid burning eye and skin
precaution for ventilation◆
To avoid harm air poisoning and choking accident happening(CO2 and welding smog
is harmful to health),ventilation and effective breath protection appliance must be
prepared so as to meet local requirement of law and regulation .
CAUTION! AVOID WELDING MACHINE DAMAGE AND FIRE ARISING
preven◆t welding machine damage or fire arising from over-heat
keep the machine 20cm away from wall ，or keep 50cm away from tinder
prevent welding machine damage or fire arising from sparking◆
must guard against sparking on tinder (splash，flash )，or go inside via inspiration gob
or opening
prevent welding machine impaction and damage arising from falling◆
when setting welding machine on scaffold,should be screwed firmly,enough not to
falling down（and not let gas cylinder fall down ）
should read operation manu◆al
The operation manual includes welding machine ,wire-feeder, gas regulator and so on,
please operate carefully base on reading manual
