Beware of Electric Shocks
Before welding, the yellow-green grounding wire in the power line must be grounded and the
insulation of the welding cable must be ensured.
During welding operation, do not touch live parts such as workbench, welding parts, earth
clamp, electrode holder or welding torches.
Rubber insulation pads should also be laid on the ground near the operating table for welding
operations with high no-load voltage and in wet working places.
In the welding process, do not open the machine house and side cover.
Do not touch the electrically charged parts.
Do not use cables with insufficient cross-section, damaged insulation sheaths or exposed
conductors.
Maintenance operation should be carried out after 5 minutes of disconnection of the power
supply until the power indicator is completely turned off, otherwise there is a risk of electric
shock.
Turn off all input power when transferring work place, replacing fuse, repairing or not using the
equipment.
Beware of welding fume and harmful gases
When welding steel plates with coatings or coatings, harmful fumes and gases will be produced.
Full ventilation or exhaust facilities should be used to keep fumes and toxic gases away from
the breathing area. If necessary, wear breathing protection tools.
When working in narrow places, such as boxes, boilers, cabins, etc., pleaseacceptthe
inspection of supervisors. In order to prevent hypoxia, we should fully ventilate and wear
respiratory protective equipment.
Keep ventilation system of welding machine unblocked. The minimum distance between power
source and surrounding place should be greater than 0.5m. Do not cover the inlet and outlet of
equipment to ensure smooth circulation of cooling air.
