Sealey POWERMIG6025S - Manual (Page 5)

5.2.6 Connect to main welder. Connect the other end of the umbilical
extension cable to the main welder as shown in fig.3.
5.2.7 Firstly connect the control cable (C) to the threaded connector on the
back of the main welder. Insert the plug and rotate it until it engages
with the keyway inside the socket. Engage the threaded collar with the
socket thread and screw it onto the socket body, thus pulling the plug
into full engagement.
5.2.8 Now connect the power transfer cable (P). Push the male quick
connector fully into the female socket and ensure it is fully rotated
clockwise.
5.2.9 The extended length of gas pipe protruding from this end of the
umbilical cable extension should be connected to the gas regulator on
the gas bottle. See section 5.6.
5.3 CONNECT WELDER TO ThE MAINS POWER SUPPLY.
5.3.1 Before making any electrical connections, ensure that the mains
voltage and frequency of the supply matches the electrical specification
of the welder as stated on the welder’s rating plate.
5.3.2 The welder must only be connected to a three phase power supply.
5.3.3 Refer to the section on electrical safety at the start of these instructions
for information on the correct connection of the mains power plug.
5.4. CONNECT TORCh “Euro Connection” (fig.4).
Your welder is fitted with a “Euro Connection” quick release torch.
Simply line the pins in the torch up with appropriate holes on the Wire
Feed Unit front panel connector, push in, and tighten the locking nut.
5.6 CONNECTING ThE GAS CYLINDER (fig.7 & 8).
5.6.1 Stand the gas cylinder on the platform at the rear of the welder and
secure with chain supplied. The platform is designed to support bottles
up to a maximum weight of 20kg.
5.6.2 If using Argon or Argon mixtures, you will need to use the “bull nosed
adaptor” supplied. (If you intend to use CO² gas the regulator will fit
directly onto the cylinder). If using the bull nosed adaptor, fit it to the
cylinder first and tighten with a spanner.
5.6.3 Remove regulator from box and screw it to the bull nosed adaptor (or
CO² cylinder). Slide a small jubilee clip over the gas pipe emerging
from the "Umbilical" cable extension, connect the pipe to the regulator
output and secure with the pipe clamp supplied (fig 8). Tighten the
jubilee clip. Note: The regulator supplied may differ from that illustrated.
5.6.4 Close the regulator by turning the adjusting screw anti-clockwise to
relieve the pressure on the diaphragm before opening the cylinder
valve. If this is not done, pressure from the cylinder can damage the
diaphragm and render the regulator inoperative.
5.6.5 Set the regulator flow rate to 4litres/min depending on the material to be
welded, also taking into consideration any draughts which are strong
enough to disturb the gas flow.

5.7 FIT A REEL OF WIRE. Ensure the welder is unplugged from the
mains power. The wire feed unit will accept reels of wire up to 15kg as
shown in fig.10.
5.7.1 Referring to fig.9, open the side of the reel container, and unscrew the
reel retaining knob from the end of the rotating reel holder. Push the
reel of wire onto the holder ensuring that the spool is rotating anti-
clockwise with the wire drawing off the reel from the bottom towards the
flexible wire guide that takes the wire into the wire drive compartment.
The larger spools of wire have a 'moulded in' guide tube which must
be located over the reel engagement pin on the rotating reel holder
flange (See fig.9 below). The pin, in conjunction with the reel tension
adjuster mechanism will stop heavy reels of wire from free wheeling on
the reel holder. See also 'setting wire tension' in section 6.8.
5.7.2 Retain the reel of wire on the holder by screwing the reel retaining knob
back into place as indicated in fig.10.

5.5 CONNECTING ThE WELDING CURRENT RETURN CABLE (fig.6).
5.5.1 The earthing clamp (fig.5) should be firmly attached to the piece being
welded ( or to a metal bench supporting it ), as close as possible to
the joint being made.
5.5.2 POWERMIG6025S. The quick connector at the other end of the
cable will be connected to the socket identified with a minus symbol
( - ) on the lower part of the front panel.
5.5.3 POWERMIG6035S. On the POWERMIG6035S there are two
alternative connections offering different reactance levels depending on
the type of material being welded.
5.5.4 The lefthand socket as shown below has minimum
reactance and is intended for aluminium material and
derivative alloys (Al), copper alloys (CuAl/CuSi).
5.5.5 The right hand socket has maximum reactance and is
intended for stainless steel (SS), carbon steel and low
alloys (Fe).
