Introduction; Setting Up Operation; Fit Torch To Machine; Fit Roll Changing ( If Required ) - Welding Industries Malaysia MIG210S Instruction Manual

1. INTRODUCTION

A few minutes spent reading about your
new MIG S Series welding machine will
enable you to operate your machine
efficiently and benefit from its many
features.

2. SETTING UP OPERATION

2.1 Fit Torch to Machine

Carefully align gas connection tube and
trigger connection pins with central
adaptor. Push in and tighten the lock nut.
Open the wire feed pressure arm above
the feed roll. Fit the feed roll to suit the
diameter of wire to be used.
2.2 Feed Roll Changing (if required)
Remove the feed roll-retaining knob. Pull
off feed roll. When replacing the feed roll,
note the wire size which is stamped on the
side face of the roll. The required size
must face inwards when the roll is refitted.
Ensure that the Woodruff Key is not lost.
Fit the feed roll and refit the retaining knob
using thumb and forefinger. Do not over
tighten.

2.3 Fit the Reel of Welding Wire

Turn the red plastic knob of the hub until
the concave is aligned with the black tip.
Place the reel of wire on hub so that the
wire will be drawn off from the bottom.
Ensure that the pin on the hub locates in
the hole in the side of the wire reel spool
reel. Turn the red plastic knob and make
sure the concave is not aligned with the
black tip. Use 300mm diameter 15kg
spools only.

2.4 Overrun Adjustment

Remove the red plastic knob. Tighten or
unscrew the hub tension hand nut in the
centre of the hub reel assembly until
sufficient hub friction is achieved to
prevent overrun. This adjustment should
be done with full spool of wire at maximum
wire feed speed. Do not over tighten.

2.4 Wire Feeding

Release the wire end from reel and cut off
the bent wire end, taking care that the wire
does not unwind. Remove the nozzle and
contact tip from the welding gun.
Straighten about 10cm of the wire and
make sure that the end is as blunt as
possible (file off if necessary). A sharp end
could damage the cable liner and the
contact tip of the welding torch. Ensure the
wire is placed correctly on to the feed rolls.
Thread some wire through the feed rolls
into the guide tube and liner of the welding
cable. Close the wire feed pressure arm.
The pressure adjustment of the feed rolls
must be set so that the wire is fed evenly
into the liner and light restriction of the wire
can be made without feed rolls slipping.
Note: Excessive pressure will cause
flattening of the wire, loosening of the
wire coating and undue wear of the
rolls.

2.6 Earth Connection

The earth connection from the welder
should at all times be made directly on to
the piece to be welded. The contact
between the earth and the job should be
as large and flat as possible. All rust and
paint on the work piece should be
removed

2.7 Gas Connection

Fit hose tail and nut to the gas hose and
hold captive with the hose clamp.
Connect the gas hose to the regulator,
open the cylinder valve and the gas flow
rate is automatically set to 15 liters per
minute.
NOTE: PLUG TOP MUST BE FITTED
