For your and other’s safety, please follow the list below before welding:
1. Operator must be qualified according with the state standard.
2. The welding circuits are not insulated when welding. If you touch the two
output electrodes of the machine with your bare skin at the same time, it will
lead to electric shock, sometimes even fatal dangers. Users need to follow the
items below to avoid electric shocks.
3. Make sure the machine is off when install, repair or maintain the machine, and
all these need to be done by technical person.
4. Welding may produce fumes and gases hazardous to health. Avoid breathing
these fumes and gases. While working in limited room, use enough ventilation
and/or exhaust to keep fumes and gases away from the breathing zone, or use
the respirator. Do not weld at the same time when using of degreasing,
cleaning or spraying operations. The heat and rays of the arc can react with
these gases to form phosgene, a highly toxic gas.
5. The machine must be far away from the explosive items. Don’t weld well-closed
container. It is dangerous to weld the box hole, you should make sure there is
no flammable or toxic gas before welding.
6. Machine need to be checked by technical person if drop down or collision
happen.
Safety warnings

7. When working high above the ground, safety belt must be needed.
8. The machine insulation grade is IP21S, can't be used under the rain.
9. Put the machine on the inclined place need to avoid tilting.
10. Use the machine for pipeline thawing is prohibited.
11. Electromagnetic would affect cardiac pace maker, the cardiac pacemaker users
should consult one’s doctor first. The effect of electromagnetic to one’s health
is not confirmed, so it might have some negative effect to one’s health. Welders
should reduce the hazardous of electromagnetic.
12. This Machine is with CC mode with rated duty cycle 30%, that means machine
working 3 min need rest 7 min, when the machine over the rated duty cycle,
the inside temperature will be increase, then the machine will protect itself, the
overheat indicator on the panel will on, welding can't continue. Only when the
temperature inside the machine cool down, the overheat indicator off, then the
machine can continue to work.
13. The machine is with carton package, light weight, no lifting device.
