Introduction; Installation And Operator Instructions - Lincoln Electric HANDY MIG Operator's Manual

Introduction

The machine is a semiautomatic constant voltage DC arc
welder. The machine uses a single phase constant
voltage transformer, solid state rectifier and a DC
permanent magnet motor for feeding and welding solid
steel electrode and flux-cored electrode (for HANDY MIG)
and only flux-cored electrode (for HANDY CORE).

Installation and Operator Instructions

Read this entire section before installation or operation of
the machine.
Location and Environment
This machine will operate in harsh environments.
However, it is important that simple preventative
measures are followed to assure long life and reliable
operation.

Do not place or operate this machine on a surface with
an incline greater than 15° from horizontal.

Do not use this machine for pipe thawing.

This machine must be located where there is free
circulation of clean air without restrictions for air
movement to and from the air vents. Do not cover the
machine with paper, cloth or rags when switched on.

Dirt and dust that can be drawn into the machine
should be kept to a minimum.

This machine has a protection rating of IP21. Keep it
dry when possible and do not place it on wet ground
or in puddles.

Locate the machine away from radio controlled
machinery. Normal operation may adversely affect
the operation of nearby radio controlled machinery,
which may result in injury or equipment damage.
Read the section on electromagnetic compatibility in
this manual.

Do not operate in areas with an ambient temperature
greater than 40°C.
Duty cycle and Overheating
The duty cycle of a welding machine is the percentage of
time in a 10 minute cycle at which the welder can operate
the machine at rated welding current.
Example: 60% duty cycle:
Welding for 6 minutes
Excessive extension of the duty cycle will cause the
thermal protection circuit to activate.
The machine is protected from overheating by a
temperature sensor.

This machine is ideally suited for individuals having
access to 230 volt AC input power and wanting the ease
of use, quality and dependability of both metal inert gas
(MIG) welding and the Innershield electrode process (self-
shielded flux-cored welding). The machine will handle
reels of wire up to 1 Kg.
Input Supply Connection
Only a qualified electrician can connect the welding
machine to the supply network. Installation the outlet plug
to power lead and connecting the welding machine had to
be made in accordance with the appropriate National
Electrical Code and local regulations.
Check the input voltage, phase, and frequency supplied to
this machine before turning it on. The allowable input
voltage is indicated in the technical specification section of
this manual and on the rating plate of the machine. Verify
the connection of grounding wires from the machine to the
input source.
Make sure the amount of power available from the input
connection is adequate for normal operation of the
machine. The necessary fuse and cable sizes are
indicated in the technical specification section of this
manual.
