Alfa In - Welding Equipment, Gas Equipment

Machines are in all respects designed in compliance with modern trends in given category. Maximum emphasis was laid on excellent utility properties while keeping the purchase price on the very favourable level. Easy operation, low weight and distinct mobility, high output, which was, however, by no means achieved to the detriment of reliability – these are properties, which are absolutely common for ALFIN machines.
FUNCTION
For MMA method all machines are equipped with ANTISTICK, HOT-START and ARCFORCE functions (for machines 160 and 200 these functions are adjustable along 0 - 100% of welding current; HOT-START allows easy ignition of the arc by a short-term current increase compared with the preset welding current value Iw; ARC-FORCE compensates possible differences between the actual welding current and set current and ANTI-STICK reduces the risk of sticking the electrode to the weldment.
TIG
When using the TIG method the machines operate in the “normal current” mode or pulse current (in case of machines 160 and 200 the pulse is adjustable between 0.5 and 250 Hz and adjustable “lower” pulse current is 10-90% of the “upper current”).
PROTECTION
ALFIN line machines are equipped with modern integrated over voltage protection. An indispensable part of the protective equipment is a thermal sensor, which protects the power section of the machine against overheating.
ACCESSORIES
A number of accessories are available for ALFIN machines, such as welding cables, remote controllers and of course welding torches of renowned European brands.

Together with the machine the customer acquires high standard services and full technical support of ALFA IN company.

ALFIN TIG line machines abide by the philosophy of keeping the maximum utility value at the highly favourable price level. Especially very easy and user-friendly setting up of all functions and parameters in a wide range represents an invaluable contribution brought by these sophisticated devices to each modern operation.
FUNCTION
ALFIN 150 TIG HF a 150 BW TIG HF machines with their features are designed especially for TIG method welding. High frequency ignition, adjustable SLOPE DOWN function, end current and post gas are commonplace. Moreover ALFIN 150 TIG HF offer SLOPE UP and pulse welding adjustable 0,5 - 250 Hz.
For MMA method welding they are equipped with HOT-START, ARC-FORCE (default setting to approx. 35% of the actual welding current) and ANTI-STICK functions. They offer all adjustable functions standard for full-value TIG welding.

LOAD FACTOR
Welding current of 180 A at 60% (TIG) load factor allows to perform a wide range of welding activities using aluminium, stainless or bare materials.
TIG METHODS
- AC TIG with square current course
- TIG continuous
- TIG slow impuls
- TIG quick impuls
TIG MODES
- two-stroke LIFT ARC or HF
- four-stroke LIFT ARC or HF
- four-stroke BILEVEL
BILEVEL
In many cases it may prove useful to have two welding currents available with a possibility of easy change-over from one current to another (bilevel). In ALFIN 180 AC/DC this funktion id controled using button on the welding torch.
AC TIG PARAMETERS
- inverse frequency (20 - 147Hz)
- + to - ratio (15% - 65%)
- electrode diameter (1,0 - 3,2mm)
MMA METHOD
- HOT START
- ARC FORCE
- ANTI STICK

CONCEPT
ALFIN 250 MPK and 251 MF machines are designed for welding of classic and alloyed steels, aluminium and its alloys, galvanized plates and other materials. Machines are designed as compact inverter direct welding current sources. The machines are able to perform MIG BRAZING in very high quality.  During the design stage we laid the maximum emphasis on the high variability and versatility using the IGBT technology, while keeping the perfect welding properties in all welding modes.
SYNERGY
When changing the wire feed speed the parameters change along the synergic curve. In order to ensure the minimum demands on operators with respect to setting up the parameters, ALFIN 250 MPK and 251 MF machines are equipped with predefined programs for the MIG/MAG welding.
