Use Limits - Toparc PUSH PULL MB 15 Manual De Instrucciones

IMPORTANT: BEFORE PUTTING THE MACHINE INTO SERVICE, READ THIS MANUAL AND KEEP IT IN A SAFE AND
KNOWN LOCATION. THIS PRODUCT MUST ONLY BE USED FOR WELDING OPERATIONS.
1 SAFETY PRECAUTIONS
Welding can be dangerous for yourself and for other people: it is important to be aware of the safety precautions
included in this manual.
2 GENERAL DESCRIPTION
2.1 SPECIFICATIONS
The torch is supplied with a contact tube of 0.8 mm aluminum (MB15) or 1.2 mm aluminum (MB25) and a Teflon sheath
for the wire (MB15: 0.8 and 1 mm) or (MB25: 0.8 1.2 mm), which thanks to its slippery properties, is particularly suitable
for aluminum. Teflon has a low coefficient of friction, but is very resistant to abrasion. When welding for extended
periods of time with iron or stainless steel, it is advisable to replace the Teflon sheath by the metal sheath.

2.2 USE LIMITS

The torch must not be used over the specification limits (200A 15%) at the risk of important damages. In that is the
case, the torch will not be covered under warranty.
3 INSTALLATION
3.1 APPLICATION ON THE GENERATOR
Extract the metal tube located in the central fixing of the generator.
Connect the PUSH PULL torch to the generator, mount the reel
guide onto the protruding teflon liner. Fix the PUSH PULL torch by
screwing it to the centralised fixing on the generator.
Before connecting the PUSH PULL torch to the generator, select the
brass tube to insert in the Teflon sheath overhanging on the torch.
Insert and tighten the central fixing of the PUSH PULL torch by
screwing it on the central fixing of the generator.
Connect the PUSH PULL torch cable to the connector onthe
generator.
Important : For welding with aluminium wires, especially with Ø
0.6 ou 0.8 mm wires, it is extremely important to adjust the clutch
at the minimum pressure. For other wires you just need to adjust
the clutch to get the correct pressure.
Contact tube: Use a contact tube for aluminium at the wire diameter.
Select the welding program according to the wire being used.
To facilitate wire insertion into the motor part of the wire feeder, a
clean cut is advised, keep the wire straight and place
the torch as straight as possible.
3.1.2 Preparation of the wire traction assembly of the PUSH PULL torch
Use the traction roller with the correct wire groove. The diameter is represented by a groove on the side of the roller
PUSH PULL MB15 / MB 25
(A) Groove side 0.6mm / (B) Opposite side 0.8-1mm
(A) Groove side 0.8-1mm / (B) Opposite side 1.2mm
When using a blue or red torch liner (aluminium welding),
it is recommended to use accessory 91151
(see picture). This stainless steel guide tube improves the
torch liner positioning and facilitates wire feeding.
