1. SAFETY INSTRUCTIONS

1.1

ELECTRICAL SAFETY.

WARNING! It is the user’s responsibility to check the following: 

You must

check all electrical equipment and appliances

to ensure they are safe before using. 

You must 

inspect power supply leads, plugs and all electrical connections for wear and damage. 

You must

ensure the risk of

electric shock is minimised by the installation of appropriate safety devices. An RCCB (Residual Current Circuit Breaker) should be incorporated in the main

distribution board. We recommend that an RCD (Residual Current Device) is used with all electrical products. It is particularly important to use an RCD together with

portable products that are plugged into an electrical supply not protected by an RCCB. If in doubt consult a professional electrician. You may obtain a Residual Current

Device by contacting your Sealey dealer. 

You must

also read and understand the following instructions concerning electrical safety.

1.1.1.

The

Electricity At Work Act 1989

requires all portable electrical appliances, 

if used on a business premises,

to be tested by a qualified person at least

once a year by using a Portable Appliance Tester (PAT).

1.1.2.

The 

Health & Safety at Work Act 1974

makes owners of electrical appliances responsible for the safe condition of the appliance, and the safety 

of the appliance operator. 

If in any doubt about electrical safety, contact a qualified electrician.

1.1.3.

Ensure the insulation on all cables and product itself is safe before connecting to mains power supply. See 1.1.2. use a (PAT) and 1.1.1.

1.1.4.

Ensure that cables are always protected against short circuit and overload.

1.1.5.

Regularly check power supply, leads, plugs and all electrical connections for wear or damage, especially power connections to ensure none are loose. 

1.1.6.

Check the voltage marked on the product is the same as the electrical power supply to be used. Check fused plugs are fitted with correct capacity fuse.

1.1.7.

DO NOT pull or carry the powered appliance by its power supply lead. Products such as welders must not be pulled or carried by their output cables.

1.1.8.

DO NOT pull power plugs from sockets by the power cable.

1.1.9.

DO NOT use worn or damage leads, plugs or connections. Immediately replace or repair by qualified persons. A U.K. 3 pin plug with ASTA/BS approval 

is fitted. In case of damage, cut off and fit a new plug according to the following instructions (UK only - see diagram).

a) Ensure the unit is correctly earthed via a three-pin plug.

b) Connect the Green/Yellow earth wire to the earth terminal ‘E’.

c) Connect the Brown live wire to live terminal ‘L’.

d) Connect the Blue neutral wire to the neutral terminal ‘N’.

NOTE:

Models Automig190, 210, 235, & 190ARC are 230Volts single phase machines and may be used on a 13 Amp plug. 

For best results however, or for constant use at high power settings these models should be connected to a 230Volt 30Amp 

power supply. If you are unsure if there is a 30Amp supply at your premises, contact a qualified electrician before proceeding further. 

(for use of a normal 13amp supply follow plug fitting instructions). Models Automig250 & 260/ARC are 440Volt 3 phase machines.
