Electromagnetic Field
-Electromagnetic fields can interfere with various electrical and electronic devices such as
pacemakers.
-Consult your doctor before using any electric arc welder or cutting device
-Keep people with pacemakers away from your welding area when welding.
-Do not wrap cable around your body while welding.
-Wrap torch and ground cable together whenever possible.
-Keep torch and ground cables on the same side of your body.
Shielding Gas Cylinders Can Explode
High pressure cylinders can explode if damaged, so treat them carefully.
-Never expose cylinders to high heat, sparks, open flames, mechanical shocks or arcs.
-Do not touch cylinder with torch.
-Do not weld on the cylinder.
-Always secure cylinder upright to a cart or stationary object.
-Keep cylinders away from welding or electrical circuits.
-Use the proper regulators, gas hose and fittings for the specific application.
-Do not look into the valve when opening it.
-Use protective cylinder cap whenever possible
1.5 Proper Care, Maintenance and Repair
-Always have power disconnected when working on internal components.
- Do not touch or handle PC board without being properly grounded with a wrist strap. Put PC board
in static proof bag to move or ship.
-Do not put hands or fingers near moving parts such as drive rolls or fan.
H.F. RADIATION can cause interference.
- High-frequency (H.F.) can interfere with radio navigation, safety services, computers,
and communications equipment.
- Have only qualified persons familiar with electronic equipment perform this
installation.
- The user is responsible for having a qualified electrician promptly correct any interference problem
resulting from the installation.
- If notified by the FCC about interference, stop using the equipment at once.
- Have the installation regularly checked and maintained.
- Keep high-frequency source doors and panels tightly shut, keep spark gaps at correct setting, and
use grounding and shielding to minimize the possibility of interference.
ARC WELDING can cause interference.
- Electromagnetic energy can interfere with sensitive electronic equipment such as
computers and computer-driven equipment such as robots.
- Be sure all equipment in the welding area is electromagnetically compatible.
- To reduce possible interference, keep weld cables as short as possible, close
together, and down low, such as on the floor.
- Locate welding operation 100 meters from any sensitive electronic equipment.
- Be sure this welding machine is grounded.
- If interference still occurs, the user must take extra measures such as moving the welding machine,
using shielded cables, using line filters, or shielding the work area.
