MIG Welding Operation

1. Maintain labels and nameplates on the 

welder.

 These carry important information. If 

unreadable or missing, contact Weldclass for a 

replacement.

2. Avoid unintentional starting.

 Make sure the 

welder is setup correctly and you are prepared to 

begin work before turning on the welder.

3. Unplug before performing maintenance.

Always unplug the welder from its electrical outlet

before performing any inspection, maintenance, 

or cleaning procedures.

4. Never leave the welder unattended while 

energised.

 Turn power off before leaving the 

welder unattended.

5. Do not touch live electrical parts.

 Wear dry, 

insulating gloves. Do not touch the electrode or 

the conductor tong with bare hands. Do not wear 

wet or damaged gloves.

6. Protect yourself from electric shock.

 Do not 

use the welder outdoors. Insulate yourself from the 

work piece and the ground. Use non-flammable, 

dry insulating material if possible, or use dry rubber 

mats, dry wood or plywood, or other dry insulating 

material large enough to cover the area of contact 

with the work or the ground.

7. Avoid inhaling dust.

 Some dust created by 

power sanding, sawing, grinding, drilling, cutting, 

welding and other construction activities, contain 

chemicals known to cause cancer, birth defects or 

other harm. Your risk from these exposures varies, 

depending on how often you do this type of work. 

To reduce your exposure to these chemicals, work 

in a well-ventilated area, and work with approved 

safety equipment, such as dust masks that are 

specially designed to filter out microscopic 

particles.

8. People with pacemakers should consult their

physician(s) before using this machine.

9. Ensure that the unit is placed on a stable 

location before use.
